[FFmpeg-devel] [PATCH v2 0/4] avformat/avienc: update write of master index

[Tobias Rapp]

Added suggested output stream duration hinting. Uses output stream duration and
bitrate as a hint for better filesize guessing. If stream bitrate is unknown a
worst-case value is assumed.

Sidenote: Noticed during tests that most loss-less encoders don't set bitrate
and thus the options_table.h default value of 200k is used in avi_write_header.
Not sure whether to fix this per encoder or just clear bitrate somewhere in
avcodec_open2 based on AV_CODEC_PROP_LOSSLESS.


Tobias Rapp (4):
  ffmpeg: pass output stream duration as a hint to the muxer
  avformat/avienc: write chained master index only if std_compliance is
    normal or below
  avformat/avienc: add reserve_index_space option
  doc/muxers: add AVI muxer documentation
