MP4 output options
^^^^^^^^^^^^^^^^^^
--mp4_include_pssh_in_stream
MP4 only: include pssh in the encrypted stream. Default enabled.
--mp4_use_decoding_timestamp_in_timeline
If set, decoding timestamp instead of presentation timestamp will be used
when generating media timeline, e.g. timestamps in sidx and mpd. This is
to workaround a Chromium bug that decoding timestamp is used in buffered
range, https://crbug.com/398130. Default false.
--num_subsegments_per_sidx <number>
Set the number of subsegments in each SIDX box. If 0, a single SIDX box is
used per segment; if -1, no SIDX box is used; Otherwise, the muxer packs N
subsegments in the root SIDX of the segment, with
segment_duration/N/fragment_duration fragments per subsegment.
