In current FFmpeg, whenever Matroska with ProRes is demuxed it creates an atom that is just 8 bytes short of the true size necessary.
We can work around this by padding the actual packet by 8 0x00 bytes, which should result in older FFmpeg versions working fine.
An FFmpeg patch is available: http://ffmpeg.org/pipermail/ffmpeg-devel/2019-September/250724.html
Correctly sets all color settings for the context and frames, which should result in better playback in players that support these. Unfortunately it does not fix the bug that VLC and MPC-HC incorrectly assume that the ProRes encoded content is in Partial range, however most editing software does correctly detect it.
Allows overriding color format, encoder info, importing and exporting from/to ffmpeg command line and most importantly logging actual settings to the log file.
Breaks more than intended, and this way is better anyway as the error that used to show up gave no indication as to what went wrong. With this reverted it now shows that starting encoding failed.
Adds support for the full on-GPU encoding path for texture encoding, which just needs to be actually implemented.
In addition this commit also ensures better stability by catching all C/C++ exceptions that could leak to C code which can't handle this at all.
Integrates Github Actions which is much much faster than AppVeyor in all areas, and even supports multiple workflows instead of forcing everything into just one workflow like AppVeyor does. Plus we get 20 parallel builds that nearly instantly finish, which results in much faster feedback without having to run our own Jenkins CI.
The builder and packager scripts have been adjusted to add support for both Windows and Linux, and both AppVeyor and Github Actions. Additionally to that, the builder script now correctly executes x32 and x64 steps in a chain, instead of waiting for the other architecture to finish first. This further reduces build times.
Fixes a crash due to reading/writing out of bounds when the resolution, color and framerate end up different than initially expected during the creation of the encoder. While this does change the error message that appears when the encoder can't be initialized, it is better than outright crashing OBS Studio.
* Completely rewrote most of the plugin from scratch to unify the encoder class into one file, resulting in much lower code and size overhead and all optimizations being in effect for all encoders.
* Removed old ProRes encoder interface as it has been replaced with the new interface.
* Added support for NVidias H.264/AVC NVENC Encoder with all options, including the capability for YUV 4:4:4 encoding. It is slightly faster and less CPU intensive than the version included with OBS Studio.
* Added support for NVidias H.265/HEVC NVENC Encoder with all options. This finally brings the HEVC market to NVidia people in addition to the AMD people that have already been able to use this with enc-amf.
Skips a later conversion step if we can find a potential identical or better quality video format, without ignoring the color format override in the settings itself.
