Rec. 2020 is really an SDR spec, but I think HDR10 made it okay to slap
PQ on it, call it an HDR spec. Rec. 2100 came along after and formally
allowed the use of PQ/HLG, so we should use 2100 instead.
Status output related to OBS configuration is prefixed with the string
"OBS" and added padding for enabled and disabled features. This padding
was not aligned between platforms.
By moving the padding and prefix decoration into its own function,
both elements are controlled in a single place. CMake scripts were
changed to use this new function `obs_status` instead of using CMake's
`message` function directly.
sizeof(AVPacket) being a part of the public ABI is deprecated. once
av_init_packet() is removed, new packets will only be able to be
allocated with av_packet_alloc().
In ffmpeg-mux, ffmpeg-vaapi, and obs-ffmpeg-nvenc, AVPacket is allocated
at the initialization to avoid frequent allocation of AVPacket.
Includes changes to win-dshow.
Apparently the testing that was done was not sufficient enough or did
not check all test cases, so resolution/fps does not get set properly on
the virtualcam.
This causes the thread to only start when the IMediaFilter::Run/Pause
calls have been made, and stop whenever either the IMediaFilter::Stop
call has been made, or on destruction, whichever comes first.
This potentially will work around a suspected race condition that
appears to be in the WebRTC library where the filter's library will be
released while the filter is in the process of being destroyed, which
can take longer than usual if the join takes too long. Basically, fixes
a reported crash (that doesn't appear to technically be our fault) when
the filter is used with browsers when the virtualcam is deactivating in
web browsers.
This may have been the issue behind the reported firefox crashes, but
strangely, the thread should always be joinable here because it's
explicitly always created in the constructor and joined in the
destructor.
This updates the libdshowcapture submodule to the latest commit.
This also changes win-dshow CMakeList to ensure compatibility.
