mov: Add option to keep exact packet sequence after seeking

Multimedia / Libav - Derek Buitenhuis [gmail.com] - 18 March 2015 09:28 UTC

The current behavior may produce a different sequence of packets after seeking, compared to demuxing linearly from the beginning. This is because the MOV demuxer seeks in each stream individually, based on timestamp, which may set each stream at a slightly different position than if the file would have been read sequentially.

This makes implementing certain operations, such as segmenting, quite hard, and slower than need be.

Therefore, add an option which retains the same packet sequence after seeking, as when a file is demuxed linearly.
