[FFmpeg-devel] [PATCH 3/3] movenc: simplify the 'tfxd' fragment start timestamps

[Jan Ekström]

As far as can be seen, this value is supposed to be the DTS of a
fragment in smooth streaming. Thus, don't take b-picture delay and
such into mention when calculating the start timestamp. The duration
calculation requires PTS values, so it is not touched.
