[FFmpeg-devel] [Patch] mpegts: emit pes packets on completion

[Janne Grunau]

Hi,

the mpegts demuxer emits pes packets only after the start of the next
packet. This creates problems for streams with distant and rare packets
like DVB subtitles.
The attached patch emits pes packets as soon as the data is completely
written.
