I've been using Hybrid for years without issues, but in the most recent builds I've run into a bug when using MP4 Box with HEVC encoded files. After muxing the first GOP is completely black (i.e. first 250 frames), as if the I-frame data is missing entirely. When I switch to ffmpeg as the mp4 muxer I end up with stuttering playback of 20fps.
I've been using as a workaround a render into .mkv and then remuxing the mkv into .mp4 using ffmpeg on the command line and that worked well until the last two versions, when the HDR metadata I need to be embedded in the hevc stream stopped being embedded into the matroska file.
As part of my troubleshooting I did a full setting reset and reinstall of the latest Hybrid version. MP4 box crashed when the Signal PAR 1:1 was flagged, and then output video that would not decode until I flagged off RDO in the HEVC settings.
I've attached the log files for both the mp4 box and the ffmpeg encodes, and have available the output and source files in a Dropbox folder I can send you.Please, read the 'Infos needed to fix&reproduce bugs,..'-sticky before you post about a problem.
