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
What do you actually need here? An H.265 annex B bitstream, such as created by
hevc_mp4toannexb?
um, yes, I think this was a regression then (I originally had it on v3).
my fault.
