Make the filter apply the pixel aspect ratio of the input to the output.
This is more useful than forcing 1:1 PAR when playing anamorphic video
such as DVDs.
VapourSynth itself actually allows passing through the aspect ratio, but
it's in a not very useful form for us: it's per video-frame instead of
constant (i.e in VSVideoInfo). As long as we don't have a way to allow a
filter to spontaneously change output parameters, we can't use this.
(And I don't really feel like making this possible.)
When using rotation with hw decoding, and the VO does not support
rotation, vf_rotate is attempted to be inserted. This will go wrong, and
after that it can't recover because a vf_scale filter was autoinserted.
Just removing all autoinserted filters before reconfig fixes this.
This couldn't rotate by 180°. Add this, and also make the parameter in
degrees, instead of magic numbers.
For now, drop the flipping stuff. You can still flip with --vf=flip or
--vf=mirror. Drop the landscape/portrait stuff - I think this is
something almost nobody will use. If it turns out that we need some of
these things, they can be readded later.
Make it use libavfilter. Its vf_transpose implementation looks pretty
simple, except that it uses slice threading and should be much faster.
Fix all include statements of the form:
#include "libav.../..."
These come from MPlayer times, when FFmpeg was somehow part of the
MPlayer build tree, and this form was needed to prefer the local files
over system FFmpeg.
In some cases, the include statement wasn't needed or could be replaced
with mpv defined symbols.
Not needed anymore. I'm not opposed to having asm, but inline asm is too
much of a pain, and it was planned long ago to eventually get rid fo all
inline asm uses.
For the note, the inline asm use that was removed with the previous
commits was almost worthless. It was confined to video filters, and most
video filtering is now done with libavfilter. Some mpv filters (like
vf_pullup) actually redirect to libavfilter if possible.
If asm is added in the future, it should happen in the form of external
files.
No change in speed (or even slightly faster, though I tested with
progressive solid color video only), and normally we use libavformat's
vf_pullup anyway.
I didn't test the speed, but by default, this filter diverts to
libavfilter already. So this would help only if libavfilter is disabled,
or libavfilter doesn't have vf_noise (like on Libav). For these cases,
we still provide the (possibly but not necessarily) slower C
implementation of vf_noise.
This makes it multiple times slower. However, the output format (packed
YUV) isn't handled efficiently by anything to begin with, and I have no
clue we even have this filter. I guess it's one of these filters which
find some use sometimes, but are not of higher importance, which
justifies removing the faster inline asm.
We were relying on vsscript_freeScript() to take care of proper
termination. But it doesn't do that: it doesn't wait for the filters to
finish and exit at all. Instead, it just destroys all objects, which
causes the worker threads to crash sometimes.
Also, we're supposed to wait for the frame callback to finish before
freeing the associated node.
Handle this by explicitly waiting as far as we can. Probably fixes
crashes on seeking, although VapourSynth itself might also need some
work to make this case completely stable.
Before this commit, the filter attempted to keep the vsscript state
(p->se) even when the script was reloaded. Change it to destroy the
script state too on reloading. Now no workaround for LoadPlugin is
necessary, and this also fixes a weird theoretical race condition when
destroying and recreating the mpv source filter.
I hate tabs.
This replaces all tabs in all source files with spaces. The only
exception is old-makefile. The replacement was made by running the
GNU coreutils "expand" command on every file. Since the replacement was
automatic, it's possible that some formatting was destroyed (but perhaps
only if it was assuming that the end of a tab does not correspond to
aligning the end to multiples of 8 spaces).
Mainly meant to apply simple VapourSynth filters to video at runtime.
This has various restrictions, which are listed in the manpage.
Additionally, this actually copies video frames when converting frame
references from mpv to VapourSynth, and a second time when going from
VapourSynth to mpv. This is inefficient and could probably be easily
improved. But for now, this is simpler, and in fact I'm not sure if
we even can references VapourSynth frames after the core has been
destroyed.
It's not really needed to be public. Other code can just use mp_image.
The only disadvantage is that the other code needs to call an accessor
to get the VASurfaceID.
Although I at first thought it would be better to have a separate
implementation for hwaccels because the difference to software images
are too large, it turns out you can actually save some code with it.
Note that the old implementation had a small memory management bug. This
got painted over in commit 269c1e1, but is hereby solved properly.
Also note that I couldn't test vf_vavpp.c (due to lack of hardware), and
I hope I didn't accidentally break it.
This follows the (only slowly progressing) plan to replace all internal
video filters with libavfilter.
All what's left in vf_gradfun.c is the weird wrapper around vf_lavfi.c.
Always pass around mp_log contexts in the option parser code. This of
course affects all users of this API as well.
In stream.c, pass a mp_null_log, because we can't do it properly yet.
This will be fixed later.
This ended up a little bit messy. In order to get a mp_log everywhere,
mostly make use of the fact that va_surface already references global
state anyway.
This requires the caller to provide a mp_log in order to see error
messages. Unfortunately we don't do this in most places, but I guess we
have to live with it.
Since m_option.h and options.h are extremely often included, a lot of
files have to be changed.
Moving path.c/h to options/ is a bit questionable, but since this is
mainly about access to config files (which are also handled in
options/), it's probably ok.
The tmsg stuff was for the internal gettext() based translation system,
which nobody ever attempted to use and thus was removed. mp_gtext() and
set_osd_tmsg() were also for this.
mp_dbg was once enabled in debug mode only, but since we have log level
for enabling debug messages, it seems utterly useless.
This gets rid of the vf_vo pseudo-filter. It ends the idea of MPlayer's
architecture that the VO is just a (terminating) video filter. It didn't
really work for us with respect to video timing (the "end" of the video
chain isn't really made for video timing, and making it do so would be
awkward), and now we're removing it entirely. We will be able to fix
some things, such as properly draining video on reconfiguration.
I don't think this has any reason to exist. It's likely that this used
to be required by the old direct rendering infrastructure. (See
git blame output.)
Remove the inconsistent, duplicated, and insufficient scale filter
insertion code, and do it in one place instead. This also compensates
for the earlier removal of vf_match_csp() (which was in fact duplicated
code).
The algorithm to determine where to insert a filter etc. is probably the
same, though it also comes with some changes that should make debugging
easier when trying to figure out why a chain is failing to configure.
Add an "in" pseudo filter, which makes insertion of conversion filters
easier. Also change the vf->reconfig signature. At a later point, I'll
probably change format negotiation such that the generic filter code
will choose the output format, so having separate in and out params will
be useful.
Reason: I never liked it being recursive. Generally, this seems to
cause more problems than trouble, and is less flexible for access
outside of the chain.
I don't think we need these flags anymore. Simplify the code and get rid
of the vf_format struct.
There still is the vf_format.configured field, but this can be replaced
by checking for a valid image format.
This adds vf_chain, which unlike vf_instance refers to the filter chain
as a whole. This makes the filter API less awkward, and will allow
handling format negotiation better.
This function improves automatic filter insertion, but this really
should be done by the generic filter code. Remove vf_match_csp() and all
code using it as preparation for that.
This commit temporarily makes handling of filter insertion worse for
now, but it will be fixed with the following commits.
They didn't do anything.
vf_screenshot.c actually did release the previous image, but that's not
really required. At worst you could take a screenshot and get an old
frame when there's no new frame yet.
The --flip option flipped the image upside-down, by trying to use VO
support, or if not available, by inserting a video filter. I'm not sure
why it existed. Maybe it was important in ancient times when VfW based
decoders output an image this way (but even then, flipping an image is a
free operation by negating the stride).
One nice thing about this is that it provided a possible path for
implementing video orientation, which is a feature we should probably
support eventually. The important part is that it would be for free for
VOs that support it, and would work even with hardware decoding.
But for now get rid of it. It's useless, trivial, stands in the way, and
supporting video orientation would require solving other problems first.
The vf_eq context contains a very large lookup table, and the method of
setting default values caused the vf_eq context to be included in the
compiled code.
All filters now either use the generic option parser, or don't have
options. This finally finishes a transition started in 2003 (see git
commit 33b62af947).
Why are MPlayer devs so monumentally lazy? Sorry, but this takes the
cake. You had 10 years.
Mostly backwards compatible, we don't change much because we just want
to get rid of the legacy option string handling.
You can't pass an aspect as first argument anymore.
Apparently you can get this with: stereo3d=ab[2]{l,r}:sbs[2]{l,r}
So it seems the filter is redundant and can be removed.
Also see FFmpeg commit 2f11aa141a01.
Unfortunately, this forces filtering both luma and chroma, because
otherwise we'd have to deal with libavfilter's vf_noise weird handling
of YUV vs. RGB formats. Would we e.g. filter luma only, it would filter
red in RGB mode only, because it goes by component and there's no way to
distinguish YUV and RGB by just using the filter's options.
Also remove the ability to disable deinterlacing at runtime. You can
still disable deinterlacing at runtime by using the ``D`` key and its
automatical filter insertion/removal.
This will allow old filter to run libavfilter instead by calling
vf_lw_set_graph(), which turns the filter into a wrapper, using a given
libavfilter graph.
Later commits use that to automatically "reroute" a bunch of filters to
libavfilter. We want to get rid of the old MPlayer filter code, because
it's bad an unmaintained, but we still don't want to force everyone to
use vf_lavfi, so this solution will do for a while.
There are some use cases for this. For example, you can use it to set
defaults of automatically inserted filters (like af_lavrresample). It's
also useful if you have a non-trivial VO configuration, and want to use
--vo to quickly change between the drivers without repeating the whole
configuration in the --vo argument.
PIX_FMT_* -> AV_PIX_FMT_* (except some pixdesc constants)
enum PixelFormat -> enum AVPixelFormat
Losen some version checks in certain newer pixel formats.
av_pix_fmt_descriptors -> av_pix_fmt_desc_get
This removes support for FFmpeg 1.0.x, which is even older than
Libav 9.x. Support for it probably was already broken, and its
libswresample was rejected by our build system anyway because it's
broken.
Mostly untested; it does compile with Libav 9.9.
Sometimes, vf_pullup hanged on seek. This was because it never was
properly reset. Old timestamps messed up the timestamp calculations,
which made the player show frames for a ridiculously long time, which is
perceived as pausing or hanging.
PIX_FMT_VDA_VLD and PIX_FMT_VAAPI_VLD were never used anywhere. I'm not
sure why they were even added, and they sound like they are just for
compatibility with XvMC-style decoding, which sucks anyway.
Now that there's only a single vaapi format, remove the
IMGFMT_IS_VAAPI() macro. Also get rid of IMGFMT_IS_VDA(), which was
unused.
When using PIC on x86 (eg with hardened toolchains) the ebx register is
reserverd and cannot be used in assembly code.
For vf_eq we allow the compiler to use memory as input.
For vf_noise we temoporarily borrow the ebp register.
This fixes#361.

This is not needed anymore, because we decided that the PAR of the
decoded video matters, and not the PAR of the filtered video that
arrives at the VO.
This drops the --pp option, which was probably broken for a while. The
option automatically inserted the "pp" filter. The value passed to it
was ignored (which is probably broken, it always selected maximal
quality).
Inserting this filter can be done simply with --vf=pp, so this is not
needed anymore.
This means most code accessing this struct must now include hwdec.h
instead of dec_video.h. I just put it into dec_video.h at first because
I thought a separate file would be a waste, but it's more proper to do
it this way, as there are too many files which include dec_video.h only
to get the mp_hwdec_info definition.
vo_opengl always loads the hwdec backend lazily, so hwdec_request_api()
has to be called to possibly load it. This makes vf_vavpp work with
software decoding. (Hardware decoding loads the backend before the
filter is initialized, so this case is different.)
Also, the VFCTRL_GET_HWDEC_INFO call doesn't need to be checked. If it
fails, the info will be left blank.
The configure followed 5 different convetions of defines because the next guy
always wanted to introduce a new better way to uniform it[1]. For an
hypothetic feature 'hurr' you could have had:
* #define HAVE_HURR 1 / #undef HAVE_DURR
* #define HAVE_HURR / #undef HAVE_DURR
* #define CONFIG_HURR 1 / #undef CONFIG_DURR
* #define HAVE_HURR 1 / #define HAVE_DURR 0
* #define CONFIG_HURR 1 / #define CONFIG_DURR 0
All is now uniform and uses:
* #define HAVE_HURR 1
* #define HAVE_DURR 0
We like definining to 0 as opposed to `undef` bcause it can help spot typos
and is very helpful when doing big reorganizations in the code.

This one really did bite me hard (see previous commit), so enable it by
default.
Fix some cases of shadowing throughout the codebase. None of these
change behavior, and all of these were correct code, and just tripped up
the warning.
This function would probably be useful in other places too.
I'm not sure why vd.c doesn't apply the aspect if it changes size by
less than 4 pixels. Maybe it's supposed to avoid ugly results with bad
scalers if the difference is too small to be noticed normally.

Until now, video output levels (obscure feature, like using TV screens
that require RGB output in limited range, similar to YUY) still required
handling of VOCTRL_SET_YUV_COLORSPACE. Simplify this, and use the new
mp_image_params code. This gets rid of some code. VOCTRL_SET_YUV_COLORSPACE
is not needed at all anymore in VOs that use the reconfig callback. The
result of VOCTRL_GET_YUV_COLORSPACE is now used only used for the
colormatrix related properties (basically, for display on OSD). For
other VOs, VOCTRL_SET_YUV_COLORSPACE will be sent only once after config
instead of twice.
This affects VOs which just reuse the mp_image from draw_image() to
return screenshots. The aspect of these images is never different
from the aspect the screenshots should be, so there's no reason to
adjust the aspect in these cases.
Other VOs still need it in order to restore the original image
attributes.
This requires some changes to the video filter code to make sure that
the aspect in the passed mp_images is consistent.
The changes in mplayer.c and vd_lavc.c are (probably) not strictly
needed for this commit, but contribute to consistency.
Using -vf eq and changing brightness, contrast, etc. using key bindings
with e.g. "add brightness 1" didn't work well: with step width 1, the
property gets easily "stuck". This is a rounding problem: e.g. setting
gamma to 3 would actually make it report that gamma is set to 2, so
the "add" command will obviously never reach 3 with a step width of 1.
Fix this by storing the parameters as integers.
This was broken in cac7702. This commit effectively changed these
properties to use the value as reported by vf_eq, instead of the
previously set value for the "add" command. This was more robust,
but not very correct either, so we keep the new behavior and make
vf_eq report its parameters more accurately.
Move the decoder parts from vo_vdpau.c to a new file vdpau_old.c. This
file is named so because because it's written against the "old"
libavcodec vdpau pseudo-decoder (e.g. "h264_vdpau").
Add support for the "new" libavcodec vdpau support. This was recently
added and replaces the "old" vdpau parts. (In fact, Libav is about to
deprecate and remove the "old" API without deprecation grace period,
so we have to support it now. Moreover, there will probably be no Libav
release which supports both, so the transition is even less smooth than
we could hope, and we have to support both the old and new API.)
Whether the old or new API is used is checked by a configure test: if
the new API is found, it is used, otherwise the old API is assumed.
Some details might be handled differently. Especially display preemption
is a bit problematic with the "new" libavcodec vdpau support: it wants
to keep a pointer to a specific vdpau API function (which can be driver
specific, because preemption might switch drivers). Also, surface IDs
are now directly stored in AVFrames (and mp_images), so they can't be
forced to VDP_INVALID_HANDLE on preemption. (This changes even with
older libavcodec versions, because mp_image always uses the newer
representation to make vo_vdpau.c simpler.)
Decoder initialization in the new code tries to deal with codec
profiles, while the old code always uses the highest profile per codec.
Surface allocation changes. Since the decoder won't call config() in
vo_vdpau.c on video size change anymore, we allow allocating surfaces
of arbitrary size instead of locking it to what the VO was configured.
The non-hwdec code also has slightly different allocation behavior now.
Enabling the old vdpau special decoders via e.g. --vd=lavc:h264_vdpau
doesn't work anymore (a warning suggesting the --hwdec option is
printed instead).
The symptom was that "-vf scale,format=rgba" broke the vsfilter
colorspace hack in sd_ass. vf->reconfig is allowed to overwrite its
input parameter for convenience (maybe that was a bad idea).
In general, this warning can hint to actual bugs. We don't enable it
yet, because it would conflict with some unmerged code, and we should
check with clang too (this commit was done by testing with gcc).
For some reason, both m_config and m_struct are somewhat similar, except
that m_config is much more powerful. m_config is used for VOs and some
other things, so to unify them. We plan to kick out m_struct and use
m_config for everything. (Unfortunately, m_config is also a bit more
bloated, so this commit isn't all that great, but it will allow to
reduce the option parser mess somewhat.)
This commit also switches all video filters to use the option macros.
One reason is that m_struct and m_config, even though they both use
m_option, store the offsets of the option fields differently (sigh...),
meaning the options defined for either are incompatible. It's easier to
switch everything in one go.
This commit will allow using the -vf option parser for other things,
like VOs and AOs.
There was a MPOpts fullscreen field, a mp_vo_opts.fs field, and
VOFLAG_FULLSCREEN. Remove all these and introduce a
mp_vo_opts.fullscreen flag instead.
When VOs receive VOCTRL_FULLSCREEN, they are supposed to set the
current fullscreen mode to the state in mp_vo_opts.fullscreen. They
also should do this implicitly on config().
VOs which are capable of doing so can update the mp_vo_opts.fullscreen
if the actual fullscreen mode changes (e.g. if the user uses the
window manager controls). If fullscreen mode switching fails, they
can also set mp_vo_opts.fullscreen to the actual state.
Note that the X11 backend does almost none of this, and it has a
private fs flag to store the fullscreen flag, instead of getting it
from the WM. (Possibly because it has to deal with broken WMs.)
The fullscreen option has to be checked on config() to deal with
the -fs option, especially with something like:
mpv --fs file1.mkv --{ --no-fs file2.mkv --}
(It should start in fullscreen mode, but go to windowed mode when
playing file2.mkv.)

Image parameters like colorspace, color levels, and chroma location are
generally less important, and many filters don't set them correctly.
Force them instead in the generic VF code, which is probably better and
more convenient over all. So we designate this is a proper solution,
instead of a dirty hack.
libswscale doesn't seem to require this (anymore?), and libavfiltert's
vf_scale doesn't do it either. Moreover, this wasn't done for most other
subsampled formats, not even very old ones. So just remove it.
(It'd be quite easy to align on chroma boundaries with all pixel
formats, though.)
Until now, vf_scale only tried formats listed in the outfmt_list array.
Extend this and try every pixel format supported by mpv if trying
outfmt_list doesn't lead to success.
Also add some checks whether swscale really supports a given input or
output format. This was implicitly done with outfmt_list before.
ffmpeg's and the internal palette format used to have different
endianess, but that is not the case anymore. This code was forgotten
when that change was made.
Instead of handling colorspaces with VFCTRLs/VOCTRLs, make them part of
the normal video format negotiation. The colorspace is passed down like
other video params with config/reconfig calls.
Forcing colorspaces (via the --colormatrix options and properties) is
handled differently too: if it's changed, completely reinit the video
chain. This is slower and requires a precise seek to the same position
to perform an update, but it's simpler and less bug-prone. Considering
switching the colorspace at runtime by user-interaction is a rather
obscure feature, this is a good change.
The colorspace VFCTRLs and VOCTRLs are still kept. The VOs rely on it,
and would have to be changed to get rid of them. We'll do that later,
and convert them incrementally instead of in one go.
Note that controlling the output range now always works on VO level.
Basically, this means you can't get vf_scale to output full-range YUV
for whatever reason. If that is really wanted, it should be a vf_scale
option. the previous behavior didn't make too much sense anyway.
This commit fixes a few bugs (such as playing RGB video and converting
that to YUV with vf_scale - a recent commit broke this and forced the
VO to display YUV as RGB if possible), and might introduce some new
ones.
Use the video decoder chroma location flags and render chroma locations
other than centered. Until now, we've always used the intuitive and
obvious centered chroma location, but H.264 uses something else.
FFmpeg provides a small overview in libavcodec/avcodec.h:
-----------
/**
* X X 3 4 X X are luma samples,
* 1 2 1-6 are possible chroma positions
* X X 5 6 X 0 is undefined/unknown position
*/
enum AVChromaLocation{
AVCHROMA_LOC_UNSPECIFIED = 0,
AVCHROMA_LOC_LEFT = 1, ///< mpeg2/4, h264 default
AVCHROMA_LOC_CENTER = 2, ///< mpeg1, jpeg, h263
AVCHROMA_LOC_TOPLEFT = 3, ///< DV
AVCHROMA_LOC_TOP = 4,
AVCHROMA_LOC_BOTTOMLEFT = 5,
AVCHROMA_LOC_BOTTOM = 6,
AVCHROMA_LOC_NB , ///< Not part of ABI
};
-----------
The visual difference is literally minimal, but since videophiles
apparently consider this detail as quality mark of a video renderer,
support it anyway. We don't bother with chroma locations other than
centered and left, though.
Not sure about correctness, but it's probably ok.
The filter chain and the video ouputs have config() functions. They are
strictly limited to transfering the video size and format. Other
parameters (like color levels) have to be transferred separately.
Improve upon this by introducing a separate set of reconfig() functions,
which use mp_image_params to carry format parameters. This struct
contains all image format related parameters from config(), plus
additional parameters such as colorspace.
Change vf_rotate to use it, as well as vo_opengl. vf_rotate is just
an example/test case, but vo_opengl will need it later.
The intention is also to get rid of VOCTRL_SET_YUV_COLORSPACE. This
information is now handed to the VOs via reconfig(). The getter,
VOCTRL_GET_YUV_COLORSPACE, will still be needed though.
If the image is not writeable, the image actually has to be copied
beforehand. This was overlooked when converting the video chain to
reference counted images.
Fix a double free issue. This was overlooked when vf.c was changed to
free filter priv data automatically.
Can be used to refer to filters by name. Intended to be used when the
filter chain is changed at runtime.
A label can be assigned to a filter by prefixing it with '@name:', where
'name' is an user-chosen identifier. For example, a filter added with
'-vf-add @label1:gradfun=123' can be removed with '-vf-del @label1'.
If a filter with an already existing label is added, the existing filter
is replaced with the new filter (this happens for both -vf-add and
-vf-pre). If a filter is replaced, the new filter takes the position of
the old filter, instead of being appended/prepended to the filter chain
as usual. For -vf-toggle, labels are compared if at least one of the
filters has a label; otherwise they are compared by filter name and
arguments (like before). This means two filters are never considered
equal if one has a label and the other one does not.
This happens only if an option actually allocates memory (like strings).
Change filter API such that vf->priv is free'd by vf.c instead by the
filters. vf.c will free the option values as well.
These were found by the cppcheck and scan-build static analyzers. Most
of these aren't interesting (the 2 previous commits fix some interesting
cases found by these analyzers), and they don't nearly fix all warnings.
(Most of the unfixed warnings are spam, things MPlayer never cared
about, or false positives.)
libavfilter changed the way a format list is passed to vf_format. Now
you have to separate formats with "|" instead of ":". If you use "|",
it prints an annoying message on every reinit:
[format @ 0x8bbaaa0]This syntax is deprecated. Use '|' to separate the list items.
...and it will probably stop working without warning at some point in
the future.
We need some very annoying ifdeffery to detect this case, because
libavfilter version numbers are just plain incompatible between Libav
and ffmpeg. There is no other way to detect this.
(Sometimes I wonder whether ffmpeg and especially Libav actually like
causing unnecessary pain for their users, and intentionally break stuff
in the most annoying way possible. Sigh...)
Resetting the filter graph helps dealing with filters which save state
between frames. This is important especially if they modify frame timing
or emit additional frames.
Unfortunately the libavfilter API doesn't have a way to do this
directly, so we have to use a dirty trick: we recreate the whole graph,
including format negotiation down and filter string parsing. ffplay does
this too. If libavfilter somehow decides to change output format or size
from what the first run in config() returned, mpv will explode. The same
applies to vf_next_query_format() return values (although this could be
mitigated, should it really happen).
Requires recent FFmpeg/Libav git versions. Earlier versions will not
be supported, as the API is different. (A libavfilter version that
uses AVFrame instead of AVFilterBuffer is needed.)
Note that this is sort of useless, because the option parser prevents
you from making use of the full libavfilter graph syntax. This has to be
fixed later.
Most of the filter creation code (half of the config() function) has
been taken from avplay.c.
This code is not based on MPlayer's vf_lavfi. The MPlayer code doesn't
compile as it hasn't been updated through multiple libavfilter API
changes, making it completely useless as a starting point.
VFCAP_OSD was used to determine at runtime whether the VO supports OSD
rendering. This was mostly unused. vo_direct3d had an option to disable
OSD (was supposed to allow to force auto-insertion of vf_ass, but we
removed that anyway). vo_opengl_old could disable OSD rendering when a
very old OpenGL version was detected, and had an option to explicitly
disable it as well.
Remove VFCAP_OSD from everything (and some associated logic). Now the
vo_driver.draw_osd callback can be set to NULL to indicate missing OSD
support (important so that vo_null etc. don't single-step on OSD
redraw), and if OSD support depends on runtime support, the VO's
draw_osd should just do nothing if OSD is not available.
Also, do not access vo->want_redraw directly. Change the want_redraw
reset logic for this purpose, too. (Probably unneeded, vo_flip_page
resets it already.)
This allowed making the player switch the monitor video mode when
creating the video window. This was a questionable feature, and with
today's LCD screens certainly not useful anymore. Switching to a random
video mode (going by video width/height) doesn't sound too useful
either.
I'm not sure about the win32 implementation, but the X part had several
bugs. Even in mplayer-svn (where x11_common.c hasn't been receiving any
larger changes for a long time), this code is buggy and doesn't do the
right thing anyway. (And what the hell _did_ it do when using multiple
physical monitors?)
If you really want this, write a shell script that calls xrandr before
and after calling mpv.
vo_sdl still can do mode switching, because SDL has native support for
it, and using it is trivial. Add a new sub-option for this.
And support the PIX_FMT_MONOWHITE pixel format. (This is really weird:
unlike PIX_FMT_MONOBLACK, it uses white pixels. I have no idea why
libavcodec doesn't just convert the pixel format on the fly, instead of
bothering everyone with really special pixel formats.)
Use the option parser instead of sscanf. Remove the parameter changing
the field dominance (it has been marked deprecated for ages). Add a new
suboption "enabled", which can be used to disable the filter by default,
until it's enabled at runtime:
mpv -vf yadif=enabled=no
Use codec names instead of FourCCs to identify codecs. Rewrite how
codecs are selected and initialized. Now each decoder exports a list
of decoders (and the codec it supports) via add_decoders(). The order
matters, and the first decoder for a given decoder is preferred over
the other decoders. E.g. all ad_mpg123 decoders are preferred over
ad_lavc, because it comes first in the mpcodecs_ad_drivers array.
Likewise, decoders within ad_lavc that are enumerated first by
libavcodec (using av_codec_next()) are preferred. (This is actually
critical to select h264 software decoding by default instead of vdpau.
libavcodec and ffmpeg/avconv use the same method to select decoders by
default, so we hope this is sane.)
The codec names follow libavcodec's codec names as defined by
AVCodecDescriptor.name (see libavcodec/codec_desc.c). Some decoders
have names different from the canonical codec name. The AVCodecDescriptor
API is relatively new, so we need a compatibility layer for older
libavcodec versions for codec names that are referenced internally,
and which are different from the decoder name. (Add a configure check
for that, because checking versions is getting way too messy.)
demux/codec_tags.c is generated from the former codecs.conf (minus
"special" decoders like vdpau, and excluding the mappings that are the
same as the mappings libavformat's exported RIFF tables). It contains
all the mappings from FourCCs to codec name. This is needed for
demux_mkv, demux_mpg, demux_avi and demux_asf. demux_lavf will set the
codec as determined by libavformat, while the other demuxers have to do
this on their own, using the mp_set_audio/video_codec_from_tag()
functions. Note that the sh_audio/video->format members don't uniquely
identify the codec anymore, and sh->codec takes over this role.
Replace the --ac/--vc/--afm/--vfm with new --vd/--ad options, which
provide cover the functionality of the removed switched.
Note: there's no CODECS_FLAG_FLIP flag anymore. This means some obscure
container/video combinations (e.g. the sample Film_200_zygo_pro.mov)
are played flipped. ffplay/avplay doesn't handle this properly either,
so we don't care and blame ffmeg/libav instead.
Add more vf_stereo3d output formats.
Adds high quality green-magenta and yellow-blue dubois
anaglyph 3D output support.

Conflicts:
video/filter/vf_stereo3d.c
Remove screenshot_force and associated logic. Always try to use the
screenshot video filter before trying taking screenshots with the VO,
which means that --vf=screenshot now takes the role of --vf=screenshot_force.
(To make this clear, not adding a video filter is still the recommended
way to take screenshots; we just change how VF screenshots are forced.)
Preferring VO over VF and having --vf=screenshot_force used to make
sense when not all VOs supported screenshots, and some VOs had somewhat
broken screenshots (like vo_xv taking screenshots with OSD in it). But
all these issues are fixed now, so just get rid of the cruft.
Now the calculations of the final display size are done after the filter
chain. This makes the difference between display aspect ratio and window
size a bit more clear, especially in the -xy case.
With an empty filter chain, the behavior of the options should be the
same, except that they don't affect vo_image and vo_lavc anymore.
Drop queued frames on seek. Reset the internal state of some filters
that seem to need it as well: at least vf_divtc still produced some
frames using the previous PTS.
This fixes weird behavior with some filters on seeking. In particular,
this could lead to A/V desync or apparent lockups due to the PTS of
filtered frames being too far away from audio PTS.
This commit does only the minimally required work to fix these PTS
related issues. Some filters have state dependent on previously filtered
frames, and these are not automatically reset with this commit (even
vf_divtc and vf_softpulldown reset the PTS info only). Filters that
actually require a full reset can implement VFCTRL_SEEK_RESET.
In theory, vf_sub could take any format supported by swscale. But to be
sure that it's reasonably fast, only 420P was allowed. However, other
similar 8 bit planar formats will be just as fast and there's no reason
to exclude them. Even for completely different formats there doesn't
seem to be any significant advantage to force vf_sub to convert to a
simpler/more common format.
This did random things with some image formats, including 10 bit
formats. Fixes the mp_image_clear() function too.
This still has some caveats:
- doesn't clear alpha to opaque (too hard with packed RGB, and is rarely
needed)
- sets luma to 0 for mpeg-range YUV, instead of the lowest possible
value (e.g. 16 for 8 bit)
Needed because mplayer* basically tracks DAR, which makes it harder for
filters which want to keep the SAR.
The contents of this function are duplicated in a few filters, and will
be used instead of custom code as the filters are updated later.
It's not easy to tell whether the OSD/subs are empty, or if something is
drawn. In general you have to use osd_draw() with a custom callback. If
nothing is visible, the callback is never invoked. (The actual reason
why this is so "hard" is the implementation of osd_libass.c, which
doesn't allow separating rendering and drawing of OSD elements, because
all OSD elements share the same ASS_Renderer.)
To simplify avoiding copies, make osd_draw_on_image() instead of the
caller use mp_image_make_writeable(). Introduce osd_draw_on_image_p(),
which works like osd_draw_on_image(), but gets the new image allocation
from an image pool. This is supposed to be an optimization, because it
reduces the frequency of large allocations/deallocations for image data.
The result of this is that the frequency of copies needed in conjunction
with vf_sub, screenshots, and vo_lavc (encoding) should be reduced.
vf_sub now always does true pass-through if no subs are shown.
Drop the pts check from vf_sub. This didn't make much sense.
Remove the strange things the old mp_image_setfmt() code did to the
image format parameters. This includes setting chroma shift to 31 for
gray (Y8) formats and more.
Y8 + vo_opengl_old didn't actually work for unknown reasons (regression
in this branch). Fix this. The difference is that Y8 is now interpreted
as gray RGB (LUMINANCE texture) instead of involving YUV (and levels)
conversion.
Get rid of distinguishing RGB and BGR. There wasn't really any good
reason for this.
Remove mp_get_chroma_shift() and IMGFMT_IS_YUVP16*(). mp_imgfmt_desc
gives the same information and more.
mplayer's video chain traditionally used FourCCs for pixel formats. For
example, it used IMGFMT_YV12 for 4:2:0 YUV, which was defined to the
string 'YV12' interpreted as unsigned int. Additionally, it used to
encode information into the numeric values of some formats. The RGB
formats had their bit depth and endian encoded into the least
significant byte. Extended planar formats (420P10 etc.) had chroma
shift, endian, and component bit depth encoded. (This has been removed
in recent commits.)
Replace the FourCC mess with a simple enum. Remove all the redundant
formats like YV12/I420/IYUV. Replace some image format names by
something more intuitive, most importantly IMGFMT_YV12 -> IMGFMT_420P.
Add img_fourcc.h, which contains the old IDs for code that actually uses
FourCCs. Change the way demuxers, that output raw video, identify the
video format: they set either MP_FOURCC_RAWVIDEO or MP_FOURCC_IMGFMT to
request the rawvideo decoder, and sh_video->imgfmt specifies the pixel
format. Like the previous hack, this is supposed to avoid the need for
a complete codecs.cfg entry per format, or other lookup tables. (Note
that the RGB raw video FourCCs mostly rely on ffmpeg's mappings for NUT
raw video, but this is still considered better than adding a raw video
decoder - even if trivial, it would be full of annoying lookup tables.)
The TV code has not been tested.
Some corrective changes regarding endian and other image format flags
creep in.
These functions weren't specific to video filters and were misplaced
in vf.c. Move them to mp_image.c.
Fix the big endian test in vf_mpi_clear/mp_image_clear, which has been
messed up in 74df1d.
According to DOCS/OUTDATED-tech/colorspaces.txt, the following formats
are supposed to be palettized:
IMGFMT_BGR8
IMGFMT_RGB8,
IMGFMT_BGR4_CHAR
IMGFMT_RGB4_CHAR
IMGFMT_BGR4
IMGFMT_RGB4
Of these, only BGR8 and RGB8 are actually treated as palettized in some
way. ffmpeg has only one palettized format (AV_PIX_FMT_PAL8), and
IMGFMT_BGR8 was inconsistently mapped to packed non-palettized RGB
formats too (AV_PIX_FMT_BGR8). Moreover, vf_scale.c contained messy
hacks to generate a palette when AV_PIX_FMT_BGR8 is output. (libswscale
does not support AV_PIX_FMT_PAL8 output in the first place.)
Get rid of all of this, and introduce IMGFMT_PAL8, which directly maps
to AV_PIX_FMT_PAL8. Remove the palette creation code from vf_scale.c.
IMGFMT_BGR8 maps to AV_PIX_FMT_RGB8 (don't ask me why it's swapped),
without any palette use. Enabling it in vo_x11 or using it as vf_scale
input seems to give correct results.
Instead of using a callback to "capture" the image next time the filter
function is called, do it the other way around: on every filter
invocation, create a reference to the image, and return it if a
screenshot is requested. This also fixes the 1-frame delay when taking
screenshots with the filter.
This also allows simplifying screenshot.c.
Remove mp_image.width/height. The w/h members are the ones to use.
width/height were used internally by vf_get_image(), and sometimes for
other purposes.
Remove some image flags, most of which are now useless or completely
unused. This includes VFCAP_ACCEPT_STRIDE: the vf_expand insertion in
vf.c does nothing.
Remove some other unused mp_image fields.
Some rather messy changes in vo_opengl[_old] to get rid of legacy
mp_image flags and fields. This is left from when vo_gl supported DR.
Change the entire filter API to use reference counted images instead
of vf_get_image().
Remove filter "direct rendering". This was useful for vf_expand and (in
rare cases) vf_sub: DR allowed these filters to pass a cropped image to
the filters before them. Then, on filtering, the image was "uncropped",
so that black bars could be added around the image without copying. This
means that in some cases, vf_expand will be slower (-vf gradfun,expand
for example).
Note that another form of DR used for in-place filters has been replaced
by simpler logic. Instead of trying to do DR, filters can check if the
image is writeable (with mp_image_is_writeable()), and do true in-place
if that's the case. This affects filters like vf_gradfun and vf_sub.
Everything has to support strides now. If something doesn't, making a
copy of the image data is required.
Setting the size of a mp_image must be done with mp_image_set_size()
now. Do this to guarantee that the redundant fields (like chroma_width)
are updated consistently. Replacing the redundant fields by function
calls would probably be better, but there are too many uses of them,
and is a bit less convenient.
Most code actually called mp_image_setfmt(), which did this as well.
This commit just makes things a bit more explicit.
Warning: the video filter chain still sets up mp_images manually,
and vf_get_image() is not updated.
vdpau hardware decoding used the DR (direct rendering) path to let the
decoder query a surface from the VO. Special-case the HW decoding path
instead, to make it separate from DR.
Slices allowed filtering or drawing video in horizontal bands or
blocks. This allowed working on the video in smaller units. In theory,
this could bring a performance win by lowering cache pressure, as you
didn't have to keep the whole video frame in cache while filtering,
only the slice.
In practice, the slice code path was barely used for the following
reasons:
- Multithreaded decoding with ffmpeg didn't use slices. The ffmpeg
slice callback was disabled, because it can be called from another
thread, and the mplayer video chain is not thread-safe.
- There was nothing that would turn "full" images into appropriate
slices, so slices were rarely used.
- Most filters didn't actually support slices.
On the other hand, supporting slices lead to code duplication and more
complex code in general. I made some experiments and didn't find any
actual measurable performance improvements when using slices. Even
ffmpeg removed slices based filtering from libavfilter in favor of
simpler code.
The most broken thing about the slices code path is that slices can't
be queued, like it is done for images in vo.c.
For some reason, libavcodec abuses the slices rendering code path for
hardware decoding: in that case, the only purpose of the draw callback
is to pass a vdpau video surface object to video output. (It is unclear
to me why this had to use the slices code, instead of just returning an
AVFrame with the required vdpau state.)
Make this code separate within mpv, so that the internal slices code
path is not used for hardware decoding. Pass the vdpau state with
VOCTRL_HWDEC_DECODER_RENDER instead.
Remove the mencoder specific VOCTRLs.
Remove VOCTRL_DRAW_IMAGE and always set vo_driver.draw_image in VOs.
Make draw_image mandatory: change some VOs (like vo_x11) to support it,
and remove the image-to-slices fallback in vf_vo.
Remove vo_driver.is_new. This member indicated whether draw_image is
supported unconditionally, which is now always the case.
draw_image_pts is a hack until the video filter chain is changed to
include the PTS as field in mp_image. Then vo_vdpau and vo_lavc will
be changed to use draw_image.
The check determined whether the argument for .align is in bytes, or
log2(bytes). Apparently it's always in bytes for ELF i386 systems, and
this check is used for x86 inline assembler only. Even if this
assumption should be wrong, it likely won't cause much damage: the
existing code uses it only in the form ".align 4", which means in the
worst case it will try to align to 16 bytes, which doesn't cause any
problems (unless the object file format does not support such a high
alignment).
Update the filters that used this.
Quoting the GNU as manual:
For other systems, including ppc, i386 using a.out format, arm and
strongarm, it is the number of low-order zero bits the location counter
must have after advancement. For example `.align 3' advances the
location counter until it a multiple of 8. If the location counter is
already a multiple of 8, no change is needed.
Strictly speaking, 444P is higher quality than YV12, but doing this is
not very useful when playing 10 bit video with -vo opengl-old on a GPU
that doesn't support 16 bit textures.
Based on a patch by qyot27. Add the missing parts in mp_get_chroma_shift(),
which allow allocation of such images, and which make vo_opengl
automatically accept the new formats. Change the IMGFMT_IS_YUVP16_LE/BE
macros to properly report IMGFMT_444P14 as supported: this pixel format
has the highest numerical bit width identifier (0x55), which is not
covered by the mask ~0xfc. Remove 1 bit from the mask (makes it 0xf8) so
that IMGFMT_IS_YUVP16(IMGFMT_444P14) is 1. This is slightly risky, as
the organization of the image format IDs (actually FourCCs + mplayer
internal IDs) is messy at best, but it should be ok.
sws_getContextFromCmdLine_hq() was used by the screenshot code, which
now uses mp_image_swscale().
Also move the mp_sws_set_colorspace() declaration from sws_utils.h to
vf_scale.c.
Until now, screenshots with the video filter didn't add subs (unclear
whether that was an oversight or feature). Fix this and make behavior
when taking screenshots with vf_screenshot more consistent with VO
screenshots.
The change in vf_screenshot is needed, because add_subs() checks this
flag to decide whether it's allowed to mutate the image.
This commit has another user visible side effect. When taking a
screenshot each frame (using the "each-frame" mode of the screenshot
command), a normal screenshot command will stop the each-frame mode.
mp_image has this confusing distinction between the w/h and width/height
fields. w/h are the actual width and height, while width/height have a
very special meaning inside the video filter code: it's the actually
allocated width, which is also used for stride padding.
Screenshot related code abused the w/h fields to store the aspect
corrected size. Some code confused the role of w/h and width/height.
Fix these issues. For aspect corrected size, display_w/h are used, while
width/height should never be used outside vf.c internals and related
code.
This also fixes an actual bug when taking screenshots of anamorphic
video with vf_screenshot, as well as using vo_image with such videos.
The lines added with this commit were accidentally removed in commit
a0d759, which was a pure cleanup commit merged from mplayer-svn. The
difference between mplayer-svn and the mplayer2 base is that this
filter has been made PTS aware in mplayer2.
Also remove the redundant initialization of vf->priv->state.
The -zoom option enabled scaling with vo_x11. Remove the -zoom option,
and make its behavior default. Since vo_x11 has to use libswscale for
colorspace conversion anyway, which doesn't do actual extra scaling when
vo_x11 is run in windowed mode, there should be no speed difference with
this change.
The code removed from vf_scale attempted to scale the video to d_width/
d_height, which matters for anamorphic video and the --xy option only.
vo_x11 can handle these natively. The only case for which the removed
vf_scale code could matter is encoding with vo_lavc, but since that
didn't set VOFLAG_SWSCALE, nothing actually changes.
Finish renaming directories and moving files. Adjust all include
statements to make the previous commit compile.
The two commits are separate, because git is bad at tracking renames
and content changes at the same time.
Also take this as an opportunity to remove the separation between
"common" and "mplayer" sources in the Makefile. ("common" used to be
shared between mplayer and mencoder.)
Tis drops the silly lib prefixes, and attempts to organize the tree in
a more logical way. Make the top-level directory less cluttered as
well.
Renames the following directories:
libaf -> audio/filter
libao2 -> audio/out
libvo -> video/out
libmpdemux -> demux
Split libmpcodecs:
vf* -> video/filter
vd*, dec_video.* -> video/decode
mp_image*, img_format*, ... -> video/
ad*, dec_audio.* -> audio/decode
libaf/format.* is moved to audio/ - this is similar to how mp_image.*
is located in video/.
Move most top-level .c/.h files to core. (talloc.c/.h is left on top-
level, because it's external.) Park some of the more annoying files
in compat/. Some of these are relicts from the time mplayer used
ffmpeg internals.
sub/ is not split, because it's too much of a mess (subtitle code is
mixed with OSD display and rendering).
Maybe the organization of core is not ideal: it mixes playback core
(like mplayer.c) and utility helpers (like bstr.c/h). Should the need
arise, the playback core will be moved somewhere else, while core
contains all helper and common code.
