Comment (by kurosu):
profile 0, afaik, doesn't exist and means it could be anything, in
particular on how to parse the bitstream. There are a few bits that can be
parsed, but nothing that will say "we absolutely can't decode". It's not
even a "patch welcome"/"missing feature" here.
"CABAC_MAX_BIN : 100" in the log underlines this: it is not possible and
means we've already had bitstream reading errors.
We have something that looks vaguely watchable, and could maybe be fixed,
but I can't see how anybody knowing hevc would want to go beyond what
mraulet did.
Maybe we can be clearer and say that the decoded output may be total
garbage.
