Libav software decoder can't handle these. (FFmpegSource2 and LWLibavVideoSource both fail)
Using DGDecNV or libav hardware decoding also shows errors.
This seems this only happens when using Avisynth.
Lowering MT-Threads to 1 seems to somehow fix it, at least partially. Enabling 'Disable MT' does fix it here.
Seems like it's an issue with the colormatrix filter handling the video stream and Avisynth threading.
Hybrid uses the ColorMatrix filter from https://forum.doom9.org/showthread.php?t=173259 which afaik is the newest and first version to support conversions from and to Rec.2020.
=> It's not really a bug of Hybrid.
I would recommend:
a. enable 'Disable MT' for this source, or
b. switch to Vapoursynth
You could also try whether using the 64bit version from https://github.com/sorayuki/ColorMatrix/...s/tag/v2.6 helps.
But reading https://forum.doom9.org/showthread.php?t=175279 there might be issues with it and I would really recommend to not use it in Avisynth for Rec2020->Rec.709 conversions.
