Might be useful for other backends too. For context_vdpau, resize
handling, presentation, and handling the mapping state becomes somewhat
less awkward.
In some cases, such as when using the libmpv opengl-cb API, or with
certain vo_opengl backends, the main framebuffer is never accessed.
Instead, rendering is done to a FBO that acts as back buffer. This meant
an incorrect/broken bit depth could be used for dithering.
Change it to read the framebuffer depth lazily on the first render call.
Also move the main FBO field out of the GL struct to MPGLContext,
because the renderer's init function does not need to access it anymore.
Useful for testing. Unfortunately, the nVidia EGL driver ignores this,
and returns a GLES 3.2 context anyway (which it is allowed to do). Might
still be useable with ANGLE, which will really give you a GLES 2 context
if you ask for it.
When dumb mode is used (the "simple" rendering path), respect the dither
options. Options should never be ignored (except in GLESv2 mode); either
they should be respected in dumb mode, or they should disable dumb mode.
In this case, the former applies.
This actually fixes the dreaded errors during resizing. It works pretty
much like before, except each surface is reallocated before it's used.
It implies surfaces with the old size remain in the presentation queue
and will be displayed.
Don't assume 0 is an invalid object handle. vdpau with its weird API
design makes all objects indexes, with 0 being a perfectly valid and
common value. You need to use VDP_INVALID_HANDLE, which is not 0.
Don't crash if init fails at vdpau initialization. It's because
mp_vdpau_destroy(NULL) crashes. Simplify it.
Destroy output surface backed FBO before output surface. Also, strictly
bookkeep the map/unmap calls (and unmap surfaces before destroying the
FBO/texture). I can't see a change in the weird errors when resizing the
window, but I guess it's slightly more correct.
Add the GL_WRITE_DISCARD_NV symbol to header_fixes.h, because we might
fail compilation with headers that do not contain the vdpau extension
(well, probably doesn't matter).
The gl_timer_last_us() function could access samples[-1]. Fix by
coercing to unsigned, so the % will put it into index [0,max). The
real value returned in this corner case doesn't mean too much, I
guess.
As the manpage says, this has no value other than adding bugs.
It uses code based on context_x11.c, and basically does very stripped
down context creation (no alpha support etc.). It uses vdpau for
display, and maps vdpau output surfaces as FBOs to render into them.
This might be good to experiment with asynchronous presentation. For
now, it presents synchronously, with a 4 frame delay (which should whack
off A/V sync). The forced 4 frame delay is probably also why interaction
feels slower.
There are some weird vdpau errors on resizing and uninit. No idea what
causes them.
Should have done this 1000 years ago. Now GL backends can use mp_log
macros directly on the MPGLContext, instead of doing stupid things like
for example MP_WARN(ctx->vo, ...).
This is just a pointless refactor with the only goal of making
image_writer_opts.format a number.
The pointless part of it is that instead of using some sort of arbitrary
ID (in place of a file extension string), we use a AV_CODEC_ID_. There
was also some idea of falling back to the libavcodec MJPEG encoder if
mpv was not linked against libjpeg, but this fails. libavcodec insist on
having AV_PIX_FMT_YUVJ420P, which we pretend does not exist, and which
we always map to AV_PIX_FMT_YUV420P (without the J indicating full
range), so encoder init fails. This is pretty dumb, but whatever. The
not-caring factor is raised by the fact that we don't know that we
should convert to full range, because encoders have no proper way to
signal this. (Be reminded that AV_PIX_FMT_YUVJ420P is deprecated.)
The buffer_size may be updated before the process callback is called for
the first time. Or, the connection graph could change, which changes the
latency of the pipeline after mpv's output. Ensure we keep on top of
these changes by registering callbacks to update our latency estimation.
This also will set image=NULL, if the video frame is marked as hwaccel,
and could not be copied to normal RAM. This will probably change the
error message (due to screenshot_get() returning NULL, instead of making
image conversion fail at a later point), but the behavior is the same
anyway.
The function tried to do something clever but ignored the fact that
the middle button followed the left button rather than the right.

On some DVDs, title number is not necessarily the same as the (first)
PGC number. (Most often they are equal, since there's usually exactly
one PGC per title, which is likely why this issue wasn't noticed
before.) When searching for audio/subtitle metadata, we want to look
at the actual PGC we're about to play. See discussion in issue #4235.

This means the subtitles will show as "intended".
For some weird reason, --sub-ass-style-override is the option that
controls style override, which implies it's specific to ASS. While that
seems weird and doesn't always reflect reality, I don't care about that
now.
I guess that's the full extent I still care about nVidia's broken
garbage. In theory, we could always force the video mixer (which is the
only method getting the video data that works), but why bother.
It appears some device can be missing if we filter too many. In
particular, I've seen devices starting with "front" and "sysdefault"
being mapped to different hardware. I conclude that it's not sane trying
to present a nice device list to users in ALSA. It's fucked. (Although
kodi appears to attempt some intense "beautification" of the device
list, which includes parsing parameters from the device name and such.
Well, let's not.)
No other audio API requires such ridiculous acrobatics.
Apparently POLLERR can be set if poll is called while the device is in
the SND_PCM_STATE_PREPARED state. So assume that we can simply call
snd_pcm_status() to check whether the error is because the device went
away (i.e. we expect it to return ENODEV if this happened).
This avoids sporadic device lost warnings and AO reloads. The actual
device lost case is untested.
We have direct rendering with hardware decoding now (so no SSE4 for
memcpy from GPU memory required), and also OpenGL drivers are not so
much of a problem anymore with ANGLE being default.
due to the see-through nature of the title bar and our standard black
window background, the title bar appears dark grey opposed to the
expected light grey.
we change the window background to white but at the same time set the
background of the enclosed view to black. that way the title bar has a
white background and the background of our video stays black in all
cases. this prevents white flashing in some cases when the video is
resized with too heavy render settings.
Probably does much more:
+ add support DVB-T2
* DVB params set to AUTO by default
* MAX_CARDS: 4 -> 16
* DMX_SET_BUFFER_SIZE: 64kb -> 256kb
+ add DTV_CLEAR call before tune
+ add logic from https://github.com/olifre/mpv/commits/dvb-mixed-api-scan
* rename type to delsys
* single playlist per adapter
* card -> adapter
* fix channels order in playlist
* update internal api
* auto fallback to old DVB API on tune
* fix DELSYS_SUPP_MASK value
* remove tone - unused
* add channel mem zeroize in config parser
+ add code from libdvbv5 for detect delivery systems

For an unknown reason, '-Wl -export-dynamic' doesn't work anymore
on the last macOS build (10.12.3 with Apple LLVM 8.0.0) so forcing
cplugins is useless because the check fails. Replacing the linker
option with its substitute '-rdynamic' do the trick.
The syms module from waf still works as expected and only the
symbols specified in mpv.def are exported.
The existing code modifies f.radius so that it is in terms of the
filter sample radius (in the source coordinate space) and has
some small errors because of this behavior.
This commit changes f.radius so that it is always in terms of
the filter function radius (in the destination coordinate space).
The sample radius can always be derived by multiplying f.radius
by filter_scale, which is the new, more descriptive name for the
previous inv_scale.
Modifications to the input coordinates should all be performed
before the final range check against the filter boundaries.
However, in the existing code, the blur/taper is applied after the
filter radius check is performed. Thus, effectively the filter radius
cutoff is applied to only-downscaling-metric-modified coordinates, not
the final coordinates.
Correct this issue and restructure the returns a bit to make it
more obvious what is being done.
Apparently fixes youtube mp4 streams if avformat_find_stream_info() is
not called.
Keeping audio/video track and other track durations separate is for
the sake of embedded subtitle streams, where we want to include the
duration of overlong subtitle streams (I think).
I'm not sure what's going on here, but it appears kodi switches forward
and backwards references for advanced VPP deinterlacing modes. This in
turn makes deinterlacing with these modes apparently work. If you don't
switch the directions, you get a stuttering mess.
As far as the libva trace dump is concerned, this makes mpv's libva
deinterlacing API use behave like kodi's, and appears to reproduce
smooth video with advanced libva deinterlacing enabled.
I'm hearing that Mesa actually does it correctly, and I'm not sure what
will happen there. For now, passing "reversal-bug=no" as sub-option to
the vavpp filter will undo this behavior.
forcibly moving a window from one screen to another is supposed to put
it in a position that looks relative the same as on the old screen, as
in bottom, top, left and right margin look the same, without changing
the window size. in some situations the old code moved the window off
screen or on top of the menu bar so it ended up at a somewhat random
position. the new code fixes some edge cases but is probably not
completely correct since the priority is to make sure that the window
ends up on the right screen.
when forcibly moving windows to a different screen with --screen or
--fs-screen we need to move the window into the screen bounds if the
window is out of bounds, otherwise it can end up on the wrong screen.
previously it always recalculated the bounds and moved the window when
toggling fullscreen, now it only does the bound calculation when
changing screens.
