Why are you restricting this to one frame? And why are you not copying
the audio, too (this would test multiplexing)? After all, FLV supports AAC.
Furthermore, you are copying the video when creating the intermediate
FLV file, yet then you are decoding it at the next stage. This decoding
would necessitate a dependency on the HEVC decoder (and maybe the parser
as well as the extract_extradata bsf?). Alternatively, one can just use
codec copy when reading the intermediate file as well (the latter is my
preferred approach).
The same remarks also apply to the other patches.
