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.
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.
FFmpeg commit e67e02d15672 [1] drops avcodec.h from avformat.h includes.
Therefore we need to include it explicitly.

lavf/avformat.h: drop the avcodec.h include
Unfortunately these encoders tend to crash or freeze after after
multiple bitrate changes. Users with dynamic bitrate enabled
experience a random encoder freeze which manifests as OBS dropping to
0kb/sec and disconnecting and it's not at all obvious that dynamic
bitrate is the cause. Disable it for now until we can figure out if
there is any workaround or bug on our end.
Only use lossless encode if the capability is supported.
Set qpPrimeYZeroTransformBypassFlag to 1 for lossless.
Do not set profileGUID for lossless.
For both NVENC implementations, retry with a heavier reset because both
are unable to recover from failure lightly.
For new NVENC, warn if PVT is requested, but unsupported by the GPU.
Also retry without PVT on failure to try to catch bad cominbations.
For old NVENC, if PVT is enabled when FFmpeg failure occurs, retry
without PVT.
This was changed to default on but is not exposed for ffmpeg nvenc.
Where cards without temporal AQ support will fail to initialize and we
cannot do checks beforehand. This exposes the parameter to allow users
to disable this feature when using the ffmpeg implementation.
This commit adds a repeat_headers setting which will allow sps/pps
repetition and AUDs(access unit delimiters) .
Repetition is ensured by h264config->repeatSPSPPS &
h264config->disableSPSPPS;
the two parameters are set by nvenc to true on default.
When video headers repetition is required, we set the second in
jim-nvenc to false so that SPS/PPS are written into bitstream.
The first parameter could be omitted but is exposed since repetition of
video headers might not be required.
When headers repetition is enabled, we also enable AUD to facilitate
decoding.
Typically the video headers repetition will be useful for mpegts and
DVB broadcast decoders.
Add support for VIDEO_CS_SRGB.
Use SMPTE 170M for 601 instead of undef/BT470BG. This is the
American/Chromium way of handling 601.
Add color metadata to the container file as well via ffmpeg-mux.
If we fallback to ffmpeg NVENC, the error from new NVENC might still be
present in the encoder structure. Given that this provides a lot more
actionable information to the user, let's use it if possible.
Code submissions have continually suffered from formatting
inconsistencies that constantly have to be addressed. Using
clang-format simplifies this by making code formatting more consistent,
and allows automation of the code formatting so that maintainers can
focus more on the code itself instead of code formatting.
According to nvidia's documentation using b-frames as reference results in
a slight quality improvement with no/negligible performance impact and is
recommended to be enabled by default when using multiple b-frames.
Adds VBR rate control mode, adds a lookahead option, adds psycho visual
tuning option, removes level property (now always set to 'auto'),
removes "2pass" option (replaced by new "Max Quality" preset which uses
2pass by default), modifies a few defaults, and updates their locale
text.
When this was being fixed up, the incorrect function name was used --
however it still compiled because the author was using the newer FFmpeg
version at the time.
The "default" preset is not an actual default, but something Nvidia
decided to just call that way. It yields the worst quality per bitrate
out of all the presets, for no actual benefits. The actual FFmpeg
default is the hq one, which yields the best quality, especially when
twopass mode is enabled.
I can't think of a way to keep the "default" preset in a non-confusing
way, and as it gives no known benefits, might as well just remove it
entirely.
(Jim edit: Also made it so that if the settings have it set to
"default", it automatically treats it as "hq")
