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
