mixer_setvolume() accepts float values for volume, but used the
integer function av_clip() to limit range, losing the fractional part
as a side effect. Change the code to use av_clipf() instead. For most
uses this shouldn't make any real difference; actual AO volume
settings may not have that much precision anyway.
af_volnorm can process either int16_t or float audio data. The float
version used 0 to INT_MAX as full value range, when it should be 0 to
1. This effectively disabled the filter (due to all input being
considered to fall in the silence range). Fix.

Something produces corrupt Matroska files with audio tracks that have
SamplingFrequency set to 44100 and OutputSamplingFrequency to 96000,
when the correct playback rate is 44100. Add a special case for this
44100/96000 combination and override it to 44100/44100; it's unlikely
that anyone would ever want to use this 44100/96000 combination for
real in valid files.
Ensure that even if a seek is inaccurate it will not show video from
outside the defined timeline. Previously, seeking to the beginning of
a segment could show frames from before the start of the segment if
the seek was done in inaccurate mode and the demuxer seeked to an
earlier position. Now hr-seek machinery is used to skip at least the
frames that should not be part of playback timeline at all.
Now external subtitles essentially use the playback time, instead of
the segment time.
This is more useful when using external subtitles with mkv ordered
chapters. The previous behavior is not necessarily incorrect, and e.g.
makes it easier to use subtitles directly extracted from ordered
chapters segments. But we consider the new behavior more useful.
Also see commit 06e3dc8.
This is simpler and more useful. We could add a new switch for the old
functionality, but that would probably be more confusing than helpful.
When passing only a single file to the command line, this commit
shouldn't change behavior.
(Classic mplayer provided both features by duplicating the loop
functionality in the "playtree".)
When the last frame is displayed, and a frame step command is issued,
playback ands and advances to the next file. But before this commit,
the next file was played unpause. Fix this, and make sure pause is
kept.
Looks like unicode support was broken with this simple `fonts.conf`. Copy more
(all) of fontconfig's default `fonts.conf`.

This causes trouble when a hw device is used:
pcm_hw.c:514:(snd_pcm_hw_delay) SNDRV_PCM_IOCTL_DELAY failed (-77): File descriptor in bad state
when running mpv test.mkv --ao=alsa:device=iec958,alsa and pausing
during playback.
Historically, mplayer usually did not call snd_pcm_delay() (which is
called by get_delay()) while paused, so this problem never showed up.
But at least mpv has changes that cause get_delay() to be called when
updating the status line (see commit 3f949cf).
It's possible that calling snd_pcm_delay() is not always legal when the
audio is paused, and at least fails with the error message mentioned
above is the device is a hardware device. Change get_delay() to return
the last delay before the audio was paused. The intention is to get a
continuous playback status display, even when pausing or frame stepping,
otherwise we could just return the audio buffer fill status in
get_delay() or even just 0 when paused.
Setting some subtitle options may lead to incorrect rendering of complex
ASS subtitle scripts, such as displaced signs or visual artifacts. The
user should be made aware that this can happen.
In theory, libass could make using some of these options relatively
safe, but it doesn't.
Note that there are potentially much more options that could in theory
break subtitle rendering, but add a warning only to the most fragile
ones.
Before this commit, the --osd-* options (like --osd-font-size etc.)
configured both the OSD and subtitle font. Make them separate, and add
--sub-text-* options (like --sub-text-size etc.). Now --osd-* affects
the OSD font only, and --sub-text-* unstyled text subtitles only.
They were more or less grouped by usefulness, but since everything
else in the manpage is sorted alphabetically, it's better to be
consistent and sort these options as well.
The premultiplied-alpha hack is changed:
- The first stage now uses a colormod of black with an unmodified
texture. This saves on applying the AND mask of 0xFF000000 to keep
alpha only.
- The second stage no longer uses an AND mask, but only an OR mask of
0xFF000000 to cancel out alpha.
- The texture uploads are no longer done using SDL_LockTexture,
SDL_ConvertPixels, SDL_UnlockTexture when the mpv pixel format matches
the OSD's pixel format. Instead, SDL_UploadTexture is used, which
saves a copy when using the "opengl" renderer.
If ffmpeg returns AVERROR_PROTOCOL_NOT_FOUND, print a warning that
ffmpeg should be compiled with network support. Note that stream_lavf.c
itself includes a whitelist of directly supported ffmpeg protocols, so
it can't happen that a completely unknown/madeup protocol triggers
this message. (Unless the ffmpeg:// or lavf:// prefixes are used.)
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.
For 9-15 bit material, cutting off the lower bits leads to significant
quality reduction, because these formats leave the most significant bits
unused (e.g. 10 bit padded to 16 bit, transferred as 8 bit -> only
2 bits left). 16 bit formats still can be played like this, as cutting
the lower bits merely reduces quality in this case.
This problem was encountered with the following GPU/driver combination:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 9.0.1
It appears 16 bit support is rather common on GPUs, so testing the
actual texture depth wasn't needed until now. (There are some other Mesa
GPU/driver combinations which support 16 bit only when using RG textures
instead of LUMINANCE_ALPHA. This is due to OpenGL driver bugs.)
The extension checking logic was broken, which reported OpenGL 3 if the
OpenGL .so exported OpenGL 3-only symbols, even if the reported OpenGL
version is below 3.0. Fix it and simplify the code a bit. Also never
fail hard if required functions are not found. The caller should check
the capability flags instead. Give up on the idea that we should print
a warning if essential functions are not found (makes loading of ancient
legacy-only extensions easier).
This was experienced with the following version strings:
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2
OpenGL version string: 1.4 Mesa 9.0.1
(Possibly reports a very old version because it has no GLSL support,
and thus isn't even GL 2.0 compliant.)
Uses the same trick as the planarization code to turn per-sample memcpy
calls into mov instructions. Makes decoding a ~25min 48000Hz 2ch floatle
audio file faster from 3.8s to 2.7s.
Change from gamma 2.2 to the slightly more precise 1/0.45 as per BT.709.
https://www.itu.int/rec/R-REC-BT.709-5-200204-I/en mentions a value of
γ=0.45 for the conceptual non-linear precorrection of video signals.
This is approximately the inverse of 2.22, and not 2.20 as the code had
been using until now.
The warnings in demux_mpg were silenced by additional no-operation
casts.
A variable in ass_mp was used only for some versions of libass; now the
declaration is in that version #ifdef too to avoid a compiler warning.
This mainly serves as a fallback for platforms where nothing better is
available; also as a debugging help. Both the audio and video driver are
not first class - the audio driver lacks delay detection, and the video
driver only supports a single YUV color space.
Configure options: --disable-sdl2 to disable SDL 2.0+ detection,
--disable-sdl to disable SDL 1.2+ detection. Both options need to be
specified to turn off SDL support entirely.
Now, extra_ldflags ought to only consider LDFLAGS, and all libraries
shall go into libs_mplayer. In the end, the command line first contains
extra_ldflags, and then libs_mplayer.
So altogether this change has the effect that libraries get added to the
linker command line in the order the configure script checks them.
Previously there was some reordering due to some checks adding libraries
to libs_mplayer and some to extra_ldflags.
This is better than having just the operating system type decide the
wakeup period, as e.g. when compiling for Win32/cygwin, a wakeup period
of 0.5 would work perfectly fine.
Instead, the default wakeup period is now only decided by availability
of a working select() system call (which is the case on cygwin but not
mingw and MSVC) AND a vo that can provide an event file descriptor or a
similar hack (vo_corevideo). vos that cannot do either need polling for
event handling and now can set the wakeup period to 0.02 in the vo code.
If one of the bundled libraries is pointing to a missing dylib stop the
bundling and exit with an error. This can happen if the user uninstalled a
dependency after he built the binary/libraries.
