xylosper 1a1504914a vd_lavc: reset last_sample_aspect_ratio in uninit_avctx()
In init_vo(), if sh->aspect is 0 or last_sample_aspect_ratio is set,
sh->aspect is overwritten. With software decoding fallback behaviour,
this makes the aspect ratio from container ignored since
last_sample_aspect_ratio is already set in first try with hardware
decoding.

wm4 6cec60a454 core: add --deinterlace option, restore it with resume functionality
The --deinterlace option does on playback start what the "deinterlace"
property normally does at runtime. You could do this before by using the
--vf option or by messing with the vo_vdpau default options, but this
new option is supposed to be a "foolproof" way.

The main motivation for adding this is so that the deinterlace property
can be restored when using the video resume functionality
(quit_watch_later command).

Implementation-wise, this is a bit messy. The video chain is rebuilt in
mpcodecs_reconfig_vo(), where we don't have access to MPContext, so the
usual mechanism for enabling deinterlacing can't be used. Further,
mpcodecs_reconfig_vo() is called by the video decoder, which doesn't
have access to MPContext either. Moving this call to mplayer.c isn't
currently possible either (see below). So we just do this before frames
are filtered, which potentially means setting the deinterlacing every
frame. Fortunately, setting deinterlacing is stable and idempotent, so
this is hopefully not a problem. We also add a counter that is
incremented on each reconfig to reduce the amount of additional work per
frame to nearly zero.

The reason we can't move mpcodecs_reconfig_vo() to mplayer.c is because
of hardware decoding: we need to check whether the video chain works
before we decide that we can use hardware decoding. Changing it so that
this can be decided in advance without building a filter chain sounds
like a good idea and should be done, but we aren't there yet.

Stefano Pigozzi 49849190dd cocoa_common: remove most of the special handling for cursor autohide
This is mostly related to the fullscreen behaviour. cecbd8864 introduces an
option to make mpv behave like a OSX user would expect. This commit changes
the Cocoa parts of the code to be consistent with the behaviour on X11. Old
behaviour is still available through the option mentioned in cecbd8864.

There is still custom logic in the cocoa backend and it can probably be moved
to core:

  * Don't perform autohide if the mouse is down
  * Don't perform autohide outside of the video window

Fixes #218 (by accident)

wm4 a5183a761c x11: add window icon
The png file added to etc/ are taken from the link mentioned in commit
303096b, except that they have been converted to 16 bit, sRGB (with
color profile info dropped, if there was one), and transparent pixels
reset for better compression.

The file x11_icon.bin is generated by gen-x11-icon.sh. I'm adding it to
the git repo directly, because the script requires ImageMagick, and we
don't want to make building even more complicated.

The way how this is done is basically a compromise between effort
required in x11_common.c and in gen-x11-icon.sh. Ideally, x11_icon.bin
would be directly in the format as required by _NET_WM_ICON, but trying
to write the binary width/height values from shell would probably be a
nightmare, so here we go.

The zlib code in x11_common.c is lifted from demux_mkv.c, with some
modifications (like accepting a gzip header, because I don't know how to
make gzip write raw compressed data).

wm4 0c7978cf9c input: deal with spurious X11 LeaveNotify events
If the mpv window is unfocus, clicking on the OSC should focus the
window (done by the window manager) and allow interaction with the OSC.
But somehow X sends a spurious LeaveNotify event, immediately followed
by an EnterNotify event. This happens at least with IceWM. The result is
that the OSC will disappear (due to receiving MOUSE_LEAVE). The OSC will
stay invisible, because EnterNotify isn't handled, and there's nothing
that could make the OSC appear again.

Solve this by handling EnterNotify. We cause a redundant MOUSE_MOVE
event to be sent, which triggers the code to make the OSC visible. We
have to remove the code from input.c, which ignores redundant mouse move
events.

Since the code ignoring redundant mouse move events is still needed on
Windows, move that code to w32_common.c. The need for this is documented
in the code, also see commit 03fd2fe. (The original idea was to save
some code by having this code in the core, but now it turns out that
this didn't quite work out.)

triggered this condition, and make fbotex_init() "nicer" by just failing

wm4 df9639d755 gl_video: fix odd video sizes with PBOs
Odd video sizes if pixel formats with chroma subsampling and PBOs were
used, garbage was rendered. This was because the PBO path created
buffers with an unpadded size, and then tried to upload a padded
image to it. Fix it by explicitly setting the padded size. (As with
the non-PBO path, we rely that image allocations are somehow padded,
which is normally the case.)

Alexander Preisinger 58e826e6f2 wayland: shm based software rendering
A wayland output based on shared memory. This video output is useful for x11
free systems, because the current libGL in mesa provides GLX symbols. It is also
useful for embedded systems where the wayland backend for EGL is not
implemented like the raspberry pi.

At the moment only rgb formats are supported, because there is still no
compositor which supports planar formats like yuv420p. The most used compositor
at the moment, weston, supports only BGR0, BGRA and BGR16 (565).

The BGR16 format is the fastest to convert and render without any noticeable
differences to the BGR32 formats. For this reason the current (very basic)
auto-detection code will prefer the BGR16 format. Also the weston source code
indicates that the preferred format is BGR16 (RGB565).

There are 2 options:
    * default-format (yes|no)  Which uses the BGR32 format
    * alpha (yes|no)    For outputting images and videos with transparencies

Moves a good chunk of the resizing code to wayland_common.c. This makes it

It doesn't resizit it immediatly, it calcutlates the new position and size and
then shedules a resizing event. This removes the ugly callback and void pointer
from the wayland data structure.

Stefano Pigozzi d4a874f726 vo_corevideo: fix regression in colormatrix handling
Regression since 18b6c01d92. That commit changed the colorspace handling to
always reinit the video output. Since the CVPixelBuffers are lazily created,
VOCTRL_SET_YUV_COLORSPACE was always called when the CVPixelBufferRef was NULL.

Since CoreVideo functions do not complain when called on NULL, no one noticed
that CVBufferSetAttachment, which stored the color matrix meta data was called
on NULL.

wm4 47e92b2f88 video: handle video output levels with mp_image_params
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.

wm4 c3a0721d09 video/out: don't require VOs to handle screenshot aspect specially
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.

Stefano Pigozzi a9cb2dc1b8 video: add vda decode support (with hwaccel) and direct rendering
Decoding H264 using Video Decode Acceleration used the custom 'vda_h264_dec'
decoder in FFmpeg.

The Good: This new implementation has some advantages over the previous one:

 - It works with Libav: vda_h264_dec never got into Libav since they prefer
   client applications to use the hwaccel API.

 - It is way more efficient: in my tests this implementation yields a
   reduction of CPU usage of roughly ~50% compared to using `vda_h264_dec` and
   ~65-75% compared to h264 software decoding. This is mainly because
   `vo_corevideo` was adapted to perform direct rendering of the
   `CVPixelBufferRefs` created by the Video Decode Acceleration API Framework.

The Bad:
  - `vo_corevideo` is required to use VDA decoding acceleration.
  - only works with versions of ffmpeg/libav new enough (needs reference
    refcounting). That is FFmpeg 2.0+ and Libav's git master currently.

The Ugly: VDA was hardcoded to use UYVY (2vuy) for the uploaded video texture.
One one end this makes the code simple since Apple's OpenGL implementation
actually supports this out of the box. It would be nice to support other
output image formats and choose the best format depending on the input, or at
least making it configurable. My tests indicate that CPU usage actually
increases with a 420p IMGFMT output which is not what I would have expected.

NOTE: There is a small memory leak with old versions of FFmpeg and with Libav
since the CVPixelBufferRef is not automatically released when the AVFrame is
deallocated. This can cause leaks inside libavcodec for decoded frames that
are discarded before mpv wraps them inside a refcounted mp_image (this only
happens on seeks).
For frames that enter mpv's refcounting facilities, this is not a problem
since we rewrap the CVPixelBufferRef in our mp_image that properly forwards
CVPixelBufferRetain/CvPixelBufferRelease calls to the underying
CVPixelBufferRef.

So, for FFmpeg use something more recent than `b3d63995` for Libav the patch
was posted to the dev ML in July and in review since, apparently, the proposed
fix is rather hacky.

Stefano Pigozzi acbf5e826a cocoa_common: fix window positioning with `--geometry`
Regression since ff3b98d11c. The window positioning code relied on the

constraining is performed by Cocoa only for titled windows.

wm4 d69b39512d vf_eq: fix behavior when changing parameters
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.

wm4 2508f38a92 vaapi: use highest available profile, instead of mapping it exactly

wm4 adfb71b79e vdpau: don't try to match codec profiles
Instead, do what MPlayer did all these years. It worked for them, so
there's probably no reason to change this.

Apparently fixes playback with some files, where the VDPAU decoder does
not formally support a profile, but decoding works with a more powerful
profile anyway.

Though note that MPlayer did this because it couldn't do it in a better
way (no decoder reported profiles available when creating the VDPAU
decoder), so it's not entirely clear whether this is a good idea. An
alterbative implementation might try to map the profiles exactly, and
do some fall backs if the exact profile is not available. But this
hack-solution works too.

wm4 4b506525da vo_vdpau: add RGB support
Apparently this was dropped some years ago, but judging from MPlayer's
handling of this, the original code wasn't so great anyway. The new
code handling clearing of panscan borders correctly, and integrates
better with the YUV path. (Although the VDPAU API sure makes this
annoying with its separate surface types for RGB.)

Note that we create 5 surfaces for some reason - I don't think this
makes too much sense (because we can't use the deinterlacer with RGB
surfaces), but at least it reduces the amount of differences with
the YUV code path.

Clearing the borders is done by drawing a single black pixel over the
window. This sounds pretty dumb, but it appears to work well, and
there is no other API for that. (One could try to use the video mixer
for this purpose, since it has all kinds of features, including
compositing multiple RGBA surfaces and clearing the window background.
But it would require an invisible dummy video surface to make the
video mixer happy, and that's getting too messy.)

wm4 ab81af477c vo_vdpau: use color close to black as default colorkey (instead of green)
The VDPAU default colorkey, although it seems to be driver specific, is
usually green. This is a pretty annoying color, and you usually see it
briefly (as flashes) if the VDPAU window resizes.

Change it to some shade of black. The new default color is close to what
MPlayer picks as colorkey (and apparently it worked well for them):

    VdpColor vdp_bg = {0.01, 0.02, 0.03, 0};

Since our OPT_COLOR can set 8 bit colors only, we use '#020507' instead,
which should be the same assuming 8 bit colors.

Obviously, you can't use black, because black is a way too common color,
and would make it too easy to observe the colorkey effect when e.g.
moving a terminal with black background over the video window.

wm4 be2f2ff033 vd_lavc: fix comment, document hwdec video frame size trickiness
About this issue, it would be better if the surfaces could be allocated
with the real size, and the vdpau video mixer could be created with that
size as well. That would be a bit hard, because the real surface size
had to be communicated to vdpau. So I'm going with this solution. vaapi
seems to be fine with either surface size, so there's hopefully no
problem.

wm4 92720fcc0e Revert "sub: support straight alpha additionally to premultiplied alpha"
This reverts commit 689a25003f, with some
adjustments to code that was added after that commit.

I just messed up big time. We don't need this, and in fact the commit
confused straight and premultiplied alpha at one point (just a simple
inverted condition due to an oversight), which is why it looked like
it was working.

In commit 2827295 I wrote:

   Also, libva can't decide whether it accepts straight or premultiplied
   alpha for OSD sub-pictures [...]

That was just me messing up and being severely confused by my own bugs.
VA API  uses premultiplied alpha, which by the way is nice and
thoughtful of the VA API devs.

Well, this was stupid. But in the end, I'm glad that I could actually
reduce codesize by a good amount again.

wm4 2827295703 video: add vaapi decode and output support
This is based on the MPlayer VA API patches. To be exact it's based on
a very stripped down version of commit f1ad459a263f8537f6c from
git://gitorious.org/vaapi/mplayer.git.

This doesn't contain useless things like benchmarking hacks and the
demo code for GLX interop. Also, unlike in the original patch, decoding
and video output are split into separate source files (the separation
between decoding and display also makes pixel format hacks unnecessary).

On the other hand, some features not present in the original patch were
added, like screenshot support.

VA API is rather bad for actual video output. Dealing with older libva
versions or the completely broken vdpau backend doesn't help. OSD is
low quality and should be rather slow. In some cases, only either OSD
or subtitles can be shown at the same time (because OSD is drawn first,
OSD is prefered).

Also, libva can't decide whether it accepts straight or premultiplied
alpha for OSD sub-pictures: the vdpau backend seems to assume
premultiplied, while a native vaapi driver uses straight. So I picked
straight alpha. It doesn't matter much, because the blending code for
straight alpha I added to img_convert.c is probably buggy, and ASS
subtitles might be blended incorrectly.

Really good video output with VA API would probably use OpenGL and the
GL interop features, but at this point you might just use vo_opengl.
(Patches for making HW decoding with vo_opengl have a chance of being
accepted.)

Despite these issues, decoding seems to work ok. I still got tearing
on the Intel system I tested (Intel(R) Core(TM) i3-2350M). It was also
tested with the vdpau vaapi wrapper on a nvidia system; however this
was rather broken. (Fortunately, there is no reason to use mpv's VAAPI
support over native VDPAU.)

wm4 8fe4790ec8 video: redo hw decoding initialization, add --hwdec=auto
Change how the HW decoding stuff is organized, the way it's initialized
in particular. Instead of duplicating the list of supported codecs for
hwaccel decoders, add a probe function which allows each decoder to
report whether it supports a given codec.

Add an "auto" choice to the --hwdec option, which automatically enables
hardware decoding if libavcodec and/or the VO supports it.

What mpv prints on the terminal changes a bit. Now it will just print
a single line whether hw decoding is used or not (and nothing at all if
no hw decoding at all was requested). The pretty violent fallback from
hw decoding to software decoding is still quite verbose and evil-looking
though.

wm4 e978511d63 vo: unref waiting image before destroying VO driver
This is in theory more correct with respect to hardware decoding. With
hardware decoding, the VOs play the role of the video surface allocator,
and nothing is allowed to reference surfaces past the VO lifetime. But
in theory waiting_mpi could be a reference to a HW video surface, so it
should be relased before the VO is uninitialized.

wm4 d40a91e804 gl_video: handle non-mod-2 4:2:0 YUV video correctly
Allocate textures big enough to include the bottom/right borders (so the
chroma texture sizes are rounded up instead of down). Make the texture
large enough to include the additional luma border. Conceptually, we
pretend that the video frame is fully aligned, and then crop away the
unwanted borders. Filtering (even just bilinear) will access the
borders anyway, so it's possible that we might need to switch to
"harder" cropping instead, but at least pixels not close to the
border should be displayed correctly now.

Add a comment to mp_image.c about this luma border. These semantics are
kind of subtle, and the image allocation code handle this in a subtle
way too, so it's better to document this explicitly. The libavutil
image allocation code does similar things.

This introduces some changes in resize behaviour. Most importantly the window
frame is not constrained to it's screen's `visibleFrame`. Anyone who still wants
that kind of behaviour when opening a video, can use `--autofit-larger`.

Even though the size of the window is not constrained, it's position is, so
that the titlebar will always be visible. When using `--no-border` even the
position will not be constrained in any way.

wm4 fece4e3053 build: fix build with vdpau, simplify
Instead of generating vdpau_template.c with a Perl script, just include
the generated file in git. This is ok because it changes very rarely,
and the script is larger than the output it generates.

It also simplify the Makefile, and fixes the build. The problem was that
transitive dependencies do not work with generated files: there is no
dependency information yet when building it the first time. I overlooked
this because I didn't delete the .d files for testing (which contained
the correct dependencies, but only _after_ a first successful build).
2013-07-29 00:59:07 +02:00
wm4 5accc5e7c1 vdpau: split off decoder parts, use "new" libavcodec vdpau hwaccel API
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).

wm4 c28bafcfb6 mp_image_pool: make reference counting thread-safe
See previous commits. Also simplify this thing: 2 flags per pool image
are enough to avoid a weird central refcount and an associated shared
object keeping the refcount. We could even just store these two flags
in the mp_image itself (like in mp_image.flags or mp_image.priv), but
let's not for the sake of readability.

wm4 a9a6cf3b6c mp_image: make reference counting thread-safe
This hasn't been done yet, because pthreads is still an optional

We keep it as simple as possible. We (probably) don't need anything
more sophisticated, and keeping it simple avoids introducing weird
bugs. So, no atomic instructions, no fine grained locks, no cleverness.

wm4 c070fa865f m_config: refactor some things
Change how m_config is initialized. Make it more uniform; now all
m_config structs are intialized in exactly the same way. Make sure
there's only a single m_option[] array defining the options, and keep
around the pointer to the optstruct default value, and the optstruct
size as well. This will allow reconstructing the option default values
in the following commit.

In particular, stop pretending that the handling of some special options
(like --profile, --v, and some others) is in any way elegant, and make
them explicit hacks. This is really more readable and easier to
understand than what was before, and simplifies the code.

wm4 13a0e6373e mp_image: pass through colorspace info to libavfilter
This change affects vf_lavfi. Until recently, libavfilter was not
colorspace aware at all. This changed with the addition of colorspace
fields to AVFrame. libavfilter's vf_scale picks them up (as of recent
ffmpeg git). Since this support is still kind of wonky and not part of
the normal format negotiation, this won't set the correct output
colorspace, though.

Not adding a separate test for HAVE_AVFRAME_COLORSPACE. This is slightly
unclean, but on the other hand adding an explicit test seems like a
waste of effort.

Tracking is automatically de-activated once the mouse leaves the window,

wm4 202b9e8069 mp_image: create AVBuffers for all planes when converting to AVFrame
It appears the API requires you to cover all plane data with AVBuffers
(that is, one AVBuffer per plane in the most general case), because
certain code can make certain assumptions about this. (Insert rant
about how this is barely useful and increases complexity and potential
bugs.) I don't know any cases where the current code actually fails,
but we want to follow the API, so do it anyway.

Note that we don't really know whether or not planes are from a single
memory allocation, so we have to assume the most general case and create
an AVBuffer for each plane. We simply assume that the data is padded to
the full stride in the last image line. All these extra dummy references
are stupid, but the code might become much simpler once we only support
libavcodec versions with refcounting and can use AVFrame directly.

wm4 6629a95b92 options: use m_config for options instead of m_struct
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.

James Ross-Gowan d784759bc0 w32_common: show the cursor in the window border
When the cursor was in the window border, it could be hidden but it
wouldn't appear again, since mpv doesn't process mouse input there.

The code used ShowCursor, which is a horrid stateful API designed for
mouseless Win16 systems that incremented or decremented a global counter
to keep track of how many applications needed to display a special
cursor (like a busy cursor.) Replace that with a simple flag, handle
WM_SETCURSOR and use SetCursor(NULL) to hide the mouse cursor, but only
when the mouse is in the client area. DefWindowProc will set the correct
cursor on the border as long as it isn't hidden with ShowCursor.

PowerPoint also uses SetCursor(NULL) to hide the cursor when showing a
presentation, so it's probably safe.

Alexander Preisinger 3dc063a330 wayland: use a unified struct for the state
This commit removes the pointer to the single different structures for input
and window and puts them as anonymous structures inside the wayland_state
structure.

This has the disadvantage of passing the substructure to the listeners, but the
advantage is that we don't have to allocate them and check for NULL pointers.
This makes it more reliable and easier to follow.

Alexander Preisinger c5b76714a0 wayland: don't resize in gl_wayland.c
The vo_wayland_fullscreen handles resizing for the video, because the video
could still be in fullscreen mode and resizing it in gl_wayland could make it
grow or shrink.

wm4 c4b08a9a11 video: remove fullscreen flags chaos
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.)

wm4 05cf512dc5 vo: remove aspdat.asp member
This was bad, because it was the only aspdat member updated by
vo_get_src_dst_rects() instead of vo_reconfig(). Now it isn't
accessed anymore, so remove it.

wm4 eb7959e43a gl_video: add support for more rgb formats
Until now, only formats directly supported by OpenGL were supported.
This excludes various permutations of 8-bit RGB[A|0]. But we can simply
permutate the color channels in the shader, so do that. This also adds
support for all these weird RGB0 formats.

Note that we could use libavutil's pixfmt list instead of the
mp_packed_formats array, but trying to decrypt the pixfmt info would
probably end in pain, so this array with duplicated information is
actually better and shorter.

Note: I didn't actually test whether the alpha components are reproduced
correctly with alpha formats.

wm4 fcdb681822 img_format: add a mask for color class
Using the term "color class" to avoid confusion with the other
colorspace related concepts.

Also get rid of MP_IMGFLAG_FMT_MASK, since it was unused.

wm4 2134fa4e6b vf: make sure less important image params are set before/after filters
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.

wm4 d8659c9aa0 sws_utils: refactor swscale wrapper code
This splits the monolithic mp_image_swscale() function into a bunch of
functions and a context struct. This means it's possible to set
arbitrary parameters (e.g. even obscure ones without getting in the
way), and you don't have to create the context on every call.

This code is preparation for removing duplicated libswscale API usage
from other parts of the code.

wm4 48789b3546 vf_scale: remove rounding of sizes to 2 with 4:2:0
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.)
