Encoding fails with "FRAME MISMATCH" when encoding with aomenc --enable-keyframe-filtering=2 #367

Closed shssoichiro closed 3 years ago

This is likely due to the fact that keyframe filtering mode 2 is not supported by all decoders. Whatever decoder av1an is using is failing to decode the files.

I'll self-assign this and take a look.

@shssoichiro It's because --enable-keyframe-filtering=2 fails to work with FFmpeg. Av1an use ffmpeg -c copy to count the number of frames, and that just reports 0 if you use --enable-keyframe-filtering=2

I'll see if there's a way to work around it. There are like 10 different ways to get the frame count with ffmpeg, hopefully one of them will work.
