Comment (by arch1t3cht):
I now noticed that I made an error (linking a different ffmpeg version
than I thought) when reproducing this, and that the given code sample does
not actually work on latest master. It works on n6.1.1 and the underlying
issue is still present on master, but setting `has_b_frames` from outside
no longer seems to work after `326c97dd38c34508b7700265d93f98056bf60ac1`.
But the bug is still present for any actual file whose
`max_num_reorder_frames` is large enough (or not present and thus inferred
as 15). It can also be quickly reproduced with the given sample by
patching `h264_ps.c` to always read `max_num_reorder_frames` as 15.
