Yes. I already added a test for H265 in this patch:
https://patchwork.ffmpeg.org/project/ffmpeg/patch/20201123212933.3560940-1-iz...@google.com/
A video sample is attached in the patch as well. I will add a test in fate
in my followup patches after handling the packet in mkv as would have
access to output.
