Was intended to show a "nice" message on edition switching. In practice,
the message was never visible. The OSD code checks whether a demuxer is
loaded, and if not, discards the message - meaning if the OSD code
happened to run before the demuxer was fully loaded, no message was
shown. This is apparently a regression due to extensions to the OSD and
the situations in which it can be used.
Remove the broken code since it's too annoying to fix. Instead, a
default property message will be shown, which is a bit uglier, but
actually not too unuseful.
Looks quite like a bug. If you have a filter chain with only the
dynaudnorm filter, and send call av_buffersrc_add_frame(s, NULL), then
subsequent av_buffersink_get_frame() calls will return EAGAIN instead of
EOF.
This was apparently caused by a recent change in FFmpeg.
Some other circumstances (which I didn't fully analyze and which is due
to the playloop's absurd temporary-EOF behavior on seeks) then led the
decoder loop to send data again, but since libavfilter was stuck in the
EOF state now, it could never recover. It kept sending new input (due to
missing output), until the demuxer refused to return more audio packets.
Each time a filter error was printed.
Fortunately, it's pretty easy to workaround. We just mark the p->eof
flag as we send an EOF frame to libavfilter. The p->eof flag is used
only to recover from temporary EOF: it resets the filter if new data is
available again. We don't care much about av_buffersink_get_frame()
returning a broken EAGAIN state in this situation and essentially ignore
it, meaning if we get EAGAIN after sending EOF, we assume effectively
that EOF was fully reached.
This is actually a pretty important fix. eglChooseConfig() might be the
first thing that fails when porobing for desktop GL / ES2 / ES3 support,
because EGL_RENDERABLE_TYPE is set values specific to the underlying
APIs.
Not sure how the hell this worked before. EGL 1.4 implementations
certainly could fail the call with EGL_BAD_ATTRIBUTE if
EGL_RENDERABLE_TYPE has EGL_OPENGL_ES3_BIT set. It's quite possible that
many EGL implementations tolerate invalid EGLConfig values steming from
uininitialized EGLConfig values (and eglCreateWindowSurface() even is
specified to return EGL_BAD_CONFIG error code for "not valid"
EGLConfigs).
The way it should (probably) work is that selecting a RGBA framebuffer
format will simply make the compositor use the alpha. It works this way
on Wayland. On X11, this is... not done. Instead, both GLX and EGL
report two FB configs, which are exactly the same, except for the
platform-specific visual. Only the latter (non-default) points to a
visual that actually has alpha. So you can't make the pure GLX and EGL
APIs select alpha mode, and you have to override manually.
Or in other words, alpha was hacked violently into X11, in a way that
doesn't really make sense for the sake of compatibility, and forces API
users to wade through metaphorical cow shit to deal with it.
To be fair, some other platforms actually also require you to enable
alpha explicitly (rather than looking at the framebuffer type), but they
skip the metaphorical cow shit step.
So that the EGL code can use it too.
Also print the actual FB config ID, instead of nonsense. (I _think_ once
in the past a certain GLX implementation just used numeric config IDs
casted to EGLConfig - or at least that would explain this nonsense.)
Preparation for the following commits. Since at least theoretically the
config selection depends on the context type (EGL_RENDERABLE_TYPE has
separate bits for ES 2, ES 3, and desktop GL), doing it any other way
would be too painful.
For X11 garbage we have to pass some annoying parameters to EGL context
creation. Add some sort of extensible API, so that adding a new
parameter doesn't break all callers. We still want to keep it as a
single function, because it's so nice isolating all the EGL nonsense API
boilerplate like this. (Did I mention yet that X11 and EGL are garbage?)
Also somewhat simplifies the vo_flags mess in the helper internals.
Tried to open iconv with "auto" as source codepage, instead of using
the latin1 fallback. This also neutralizes the libavcodec dumbass
UTF-8 check, which discards subtitles not in UTF-8 and shows an
error message for ffmpeg CLI instead.
Fixes#3954.
The chroma alignment renormalization code forgot to account for the fact
that the chroma subsampling ratio has to be rotated.
Unfortunately, doing it this way seems to have somewhat broken the
chroma offset rotation logic for odd-sized subsampled image files. While
this is a bug, it's much, much less noticeable, so it's not nearly as
important as the bug this change fixes. Either way, a future patch needs
to still revise this logic, ideally by redesigning the entire rotation
mechanism.
Remove ad_spdif from the normal codec list, and select it explicitly.
One goal was to decouple this from the normal codec selection, so
they're less entangled and the decoder selection code can be simplified
in the far future. This means spdif codec selection is now done
explicitly via select_spdif_codec(). We can also remove the weird
requirements on "dts" and "dts-hd" for the --audio-spdif option, and it
can just do the right thing.
Now both video and audio codecs consist of a single codec family each,
vd_lavc and ad_lavc.
Conceptually cleaner, although the API claims this is equivalent.
Originally, AVCodecContext fields were used, because not all supported
libavcodec/libavutil versions had the AVFrame fields.
This is not done for chroma_sample_location - it has no AVFrame field.
Helps with gif, probably does unwanted things with other formats.
This doesn't handle --end quite correctly, but this could be added
later.
Fixes#3924.
TrueHD is a fucked up audio codec with extremely small frame sizes. Some
of these frames start with full headers, which are usually marked as
keyframes, and from which decoding can be started (or at least that's
what you'd expect).
So for such tracks we should probably trust the keyframe flags. Doesn't
really improve seek behavior, though.
Some files have audio tracks with packets that do not have a keyframe
flag set at all. I don't think there's any audio codec which actually
needs keyframe flags, so always assume an audio packet is a keyframe
(which, in Matroska terminology, means it can start decoding from that
packet).
The file in question had these set:
| + Multiplexing application: Lavf57.56.100 at 313
| + Writing application: Lavf57.56.100 at 329
Garbage produced by garbage...
There are other such files produced by mkvmerge, though. It's not
perfectly sure whether these have been produced by FFmpeg as well
(mkvmerge often trusts the information in the source file, even if it's
wrong - so other samples could have been remuxed from FFmpeg).
Fixes#3920.
Don't force CLI usage. It can be imported, and generate_C_header() and
generate_C_definitions() can be called with a file argument instead of
writing to stdout always.
This reverts commit fae7307931.
Before the waf build system was used, we had a configure script written
in shell. To drop the build dependency on Python, someone rewrote the
Python scripts we had to Perl. Now the shell configure script is gone,
and it makes no sense to have a build dependency on both Perl and
Python.
This isn't just a straight revert. It adds the new Matroska EBML
elements to the old Python scripts, adjusts the waf build system, and of
course doesn't add anything back needed by the old build system.
It would be better if this used matroska.py/file2string.py directly by
importing them as modules, instead of calling them via "python". But for
now this is simpler.
this replaces the old fullscreen with the native
macOS fullscreen. additional the
--fs-black-out-screens was removed since the new
API doesn't support it in a way the old one did.
it can possibly be re-added if done manually.
Fixes#2857#3272#1352#2062#3864
The reST contents directive is added to mpv.rst.
In wscript_build.py, the --strip-elements-with-class=contents option is
needed for the rst2man call in order to prevent the TOC from appearing
in mpv.1.
When dropping a file on mpv, either on the window
or the App bundle icon, while holding the shift
key the dropped files will be appended to the
playlist.
Fixes#2166
Allow minimizing the borderless/fullscreen window by clicking on the
taskbar button or pressing Win+Down hotkey.
Also fixes#2229 and probably fixes#2451
Remove 'Quit mpv & remember playback position'
from the menu because it conflicts with the global
logout shortcut. add separator between 'Hide' and
'Quit' for consistency with other Apps.
also rename the 'Movie' menu to 'Video'. it's a
bit more generic.
Fixes#3865
According to MSDN, GetWindowLong and SetWindowLong have been
superseded by GetWindowLongPtr and SetWindowLongPtr.
It's a cosmetic code change in this case.
Was started by Uoti Urpala in commit 5f631d1c. Although it was made part
of demux_mkv.c, it's quite obvious that it's not based on any
pre-existing demux_mkv.c code (or ebml.c/.h for that matter). Anyone
else who has touched this code every since has already agreed to LGPL
relicensing.
Currently, if init_filter fails after lavf_ctx is allocated, uninit is called
which frees lavf_ctx, but doesn't clear the pointer in spdif_ctx. So, on the
next call of decode_packet, it thinks it is already initialized and uses it,
resulting in a crash on my system.
As documented in interface-changes.rst. This makes it much easier to
follow what the heck is going on.
Whether this is adequate for real-world use is unknown.
Enca is dead. libguess is relatively useless due to not having an
universal detection mode. On the other hand, libuchardet is actively
developed.
