h264_mp4toannexb is for H.264, and will refuse to do anything with H.265:
"[AVBSFContext @ 0x55f4d346c620] Codec 'hevc' (174) is not supported by the
bitstream filter 'h264_mp4toannexb'. Supported codecs are: h264 (28)."
(Was this decoder really tested as the commit message claims?)
yes it was a couple of versions ago though: without it, the decoded
frames could not be displayed using the dragon board 820c.
however just tried again and got the error message that you mentioned;
[...]

yeah now, after removing the h264_mp4toannexb from the decoder, I can
not play any HEVC videos on the db820c.....I'll then remove HEVC from
the list of supported decoders then. It is a pity.
actually I will just remove the filter from the hevc decoder
instantiation in case some v4l2 codec (different from the one in the
db820) can still benefit
