This reverts commit 7b3feecbc2.
It's broken, hr-seek never ends at a video position before seek pts.
Not sure what I was thinking, although it did work anyway when
artificially forcing a video frame to display before seek pts.
At least there is _some_ problem if this happens. It would mean that
audio is playing slower than video. Normally, video is synced to audio,
so if audio stops playback completely, video will not advance at all.
But using things like --autosync, it's well possible that this kind of
desync happens.
Move the update_avsync_before_frame() call further down. Moving it
closer to where the time_frame value is used (and which the function
updates) should make the code more readable. With this change, there's
no need anymore to reset the time_frame value on the video reconfig
path.
Move the update_avsync_after_frame() up. Now no meaningful amount of
time passes since the previous get_relative_time() call anymore, and the
second one can be removed.
FFmpeg and Libav have the stupid practice of replacing and deprecating
API symbols on the same day. So with FFmpeg git, this is useless and
will print a compile time warning, while it's required with all stable
releases, and might lead to decoding errors with xvid/avi (apparently).
Add a comment before someone writes a patch and I have to explain it all
over again.
A small simplification. Couldn't be done before, because it was also
used by the OSD code, which required disjoint quads in a single draw
call.
Also mess with the unrelated code in gl_osd.c to simplify it a little
as well.
Now it shows one of:
- "Subtitles hidden" (sub-visibility=no)
- "Subtitles visible" (sub-visibility=yes, sub!=no)
- "Subtitles visible (but no subtitles selected)" (otherwise)
It should be a bit more self-explanatory than before. On the other hand,
I have no clue about UI issues.
This also gets close to what's reasonably possible with the OSD
expansion string syntax, which is why it looks so awful.
Hardware decoding/displaying with vo_opengl is done by replacing the
normal video textures with textures provided by the hardware decoding
API OpenGL interop code. Often, this changes the format (vaglx and vdpau
return RGBA, vda returns packed YUV).
If the format is changed, there was a chance (or at least a higher
potential for bugs) that the shader generation code could be confused by
the mismatch of formats, and would create incorrect conversions.
Simplify this by requiring the hwdec interop driver to set the format it
will return to us. This affects all fields, not just some (done by
replacing the format with the value of the converted_imgfmt field in
init_format), in particular fields like colorlevels.
Currently, no hwdec interop driver does anything sophisticated, and the
win is mostly from the mp_image_params_guess_csp() function, which will
reset fields like colorlevels to expected value if RGBA is used.
Reduces the size of gl_video.c a bit further.
This also uses a separate vertex array object for OSD elements, so the
video one can be simplified slightly.
OSD shader generation is still in gl_video.c, which leads to the strange
additional parameter to mpgl_osd_init(). The issue is that video
parameters influence the OSD shader (????), and also OSD needs to go
through the screen colormanagement.
Useful if we want to reduce the size of gl_video.c further.
To some degree this emulates traditional glDrawArrays() usage. It also
leaves a loophole for avoiding a reupload every time by leaving
ptr==NULL, although this is unused for now.
default_tex_params() and texture_size() are each called only once, so
move inline/reimplement them at the caller.
image_dw/dh were unused. texture_w/h, image_format, and component_bits
were rarely used, and can be replaced. Regroup some other fields.
Rename surface_num to surface_idx, because the former sounded like a
count, and not an index. Move fbosurface_next() closer to its callers
too.
Move the DebugMessageCallback() code to gl_utils.c (also simplify it
by always setting the callback, instead of only when it changes).
This is somewhat messy, because fbotex_init() itself was depending on
some gl_video parameters unrelated to FBO creation (like what scaler was
in use - what the fuck did this check do in this function?), so this
commit does a bit more than moving code around. In particular, the FBO
for the separate scaling intermediate step now always uses GL_NEAREST
sampling, and all FBOs are destroyed/recreated on renderer
reinitialization.
This also moves the function matrix_ortho2d() - trivial enough not to
put it into a separate commit.
Windows Intel drivers seem to reject some (AFAIK) valid GLSL. Make them
happy.

...into its own functions. The central playloop function is still too
big, but looks much cleaner now.
No changes in functionality. The code moved to handle_playback_restart()
is unindented by 1 level and moving it out of the if condition around.
The if condition is inverted and early-exits from the function. Also
some comments are changed.
mpctx->audio_delay always has the same value as opts->audio_delay. (This
was not the case a long time ago, when the audio-delay property didn't
actually write to opts->audio_delay. I think.)
Handles stupid boilerplate OpenGL requires you to handle. It's the same
code as in gl_video.c, although if no VAOs are available, the fallback
code rebinds them on every draw call instead of just once.
gl_common.c contained the function loader (which is big) and additional
utility functions (not so big, but will grow when moving more out of
gl_video.c). Just split them. There are no changes other than some
modifications to comments.
This allows seeking audio between two video frames that are relatively
far away.
The implementation of this is a bit subtle. It pretend the audio
position is different, and the actual PTS adjustment happens in audio.c
with this line:
sync_pts -= mpctx->audio_delay - mpctx->delay;
Effectively this is the same as setting sync_pts to hrseek_pts after
this line, though. (I'm actually not sure if this could be written in a
more straightforward way; probably yes.)
Some files can have audio after video has ended, and playback of the
audio-only remainder is supposed to work just fine.
Seeking is broken-ish though. Not much can be done about this, since
it's the way demuxers work. Also, such files are obscure corner cases.
But enabling hr-seek for audio after video end can improve the situation
a lot.
This helps with issue #1533. The reported also provided a command line
to produce such a file:
ffmpeg -i image.jpg -i audio.flac -threads $(nproc) \
-c:v libvpx -crf 10 -qmin 5 -qmax 55 \
-vf scale=360:-1 -sws_flags lanczos -c:a libvorbis -ac 2 \
-b:a 128K out.webm
Commit acb40644 fixed video with unaligned luma/chroma sizes. It
attempted to disable the fix for videos where it effectively does
nothing (just some minor performance paranoia), but this check was
broken - fix it by not duplicating the logic for this.
PNG uses a different component order from GL_RGBA, so we upload the
surface using the "wrong" order, and then fix it in the shader. This
breaks if a sRGB texture (GL_SRGB) is used: the hardware will not touch
the alpha channel, which means that the B component is not adjusted,
leading to incorrect output.
Just remove the use of sRGB textures completely. It might lead to a
slight slow down when playing RGB with color management enabled, but
with this combination of obscure use case with minor performance impact
it's not a meaningful disadvantage.
Unfortunately this also means that alpha is handled incorrectly with our
own color management, but alpha isn't so important and can be fixed
later. (0.0 and 1.0 are unchanged by the transfer function, so it
"mostly" works.)
Fixes#1530.
This was apparently useful for correct interlaced scaling (although I
don't know anyone who used this). It was rarely used (if at all), had an
inconvenient output format (packed YUV), and now has a better solution
in libavfilter (using the libavfilter "scale" filter via vf_lavfi).
There is no reason to keep this filter any longer.
It's entirely useless. I left it in for a while, because the analog TV
code had a transitional bug that could switch chroma planes, but it was
fixed long ago. It's also available in libavfilter.
Apparently it was completely broken and essentially did nothing. This
was broken sometime in early mpv or mplayer2 times.
Get rid of it. If you _really_ need it, wait until FFmpeg ports it from
MPlayer, which will happen very soon.
This deals with subsampled YUV video that has odd sizes, for example a
5x5 image with 4:2:0 subsampling.
It would be easy to handle if we actually passed separate texture
coordinates for each plane to the shader, but as of now the luma
coordinates are implicitly rescaled to chroma one. If luma and chroma
sizes don't match up, and this is not handled, you'd get a chroma shift
by 1 pixel.
The existing hack worked, but broke separable scaling. This was exposed
by a recent commit which switched to GL_NEAREST sampling for FBOs. The
rendering was accidentally scaled by 1 pixel, because the FBO size used
the original video size, while textures_sizes[0] was set to the padded
texture size (i.e. one pixel larger).
It could be fixed by setting the padded texture size only on the first
shader. But somehow that is annoying, so do something else. Don't pad
textures anymore, and rescale the chroma coordinates in the shader
instead.
Seems like this somehow doesn't work with rectangle textures (and
introduces a chroma shift), but since it's only used when doing VDA
hardware decoding, and the bug occurs only with unaligned video sizes, I
don't care much.
Fixes#1523.
If a file is unseekable (consider e.g. a http server without resume
functionality), but the stream cache is active, the player will enable
seeking anyway. Until know, client API user couldn't know that this
happens, and it has implications on how well seeking will work. So add a
property which exports whether this situation applies.
Fixes#1522.
This was subtly broken by commit a937ba20. Instead of framestepping over
the timeline segment boundary, it would just unpause playback, because
seeking now resets mpctx->step_frames. This was especially apparent when
doing something like "mpv *.jpg --merge-files".
Fix by restoring the step_frames field specifically if the seek is done
for switching segment boundaries. Hopefully the number fields which need
such an exception on seeking won't grow and turn this code into a mess.
With mf://, rather long frame durations are common. By default, one
frame takes 1 second. This causes the if branch changed with this commit
to always being taken, which in turn leads to the player not being woken
up correctly. (As a consequence, it "freezes" by waiting for events that
never come, and moving the mouse cursor over the window will wake it up
again and advance video.)
Obviously, the code should account for how long the video frame takes.
The code is probably still not fully correct, but for now this fixes the
issue at hand.
Fixes#1521.
Make the default value part of the option metadata, instead of doing
this in the screenshot code. Makes more sense with --list-options and
the command.c option metadata properties.
This allows getting the log at all with --no-terminal and without having
to retrieve log messages manually with the client API. The log level is
hardcoded to -v. A higher log level would lead to too much log output
(huge file sizes and latency issues due to waiting on the disk), and
isn't too useful in general anyway. For debugging, the terminal can be
used instead.
The previous default ("no") seemed to be equivalent to "min" in practice
(though it might depend on the website, which is even worse).
Better just select the best stream by default.
