[FFmpeg-devel] [PATCH 0/3] avcodec/h264dec: Fix dropped frames when draining

[arch1t3cht]

Fix one or more frames being dropped when starting decoding at a SEI
recovery point that is very close to the end of the stream
(specifically, which is less than 2 * has_b_frames frames before the
end of the stream in decoding order). One case of this was reported
in ticket #10936.

Tested for regressions using FATE. If necessary I can also try to add
a test for the previously broken behavior.

There's now a bit of code duplication between
h264_select_output_frame and send_next_delayed_frame (or, rather,
there was already some code duplication and this patch
adds a bit more). But this probably cannot be avoided without a larger
refactor to, say, also call h264_select_output_frame in
send_next_delayed_frame instead of manually selecting a frame, which
I don't feel confident enough to do myself.

arch1t3cht (3):
  avcodec/h264dec: Properly mark frames as recovered when draining
  avcodec/h264dec: Handle non-recovered frames when draining
  avcodec/h264dec: Reindent after the previous commit
