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.
