Process ctts atom and apply pts on outgoing buffers' timestamp (5.97 KB, patch)
2007-03-27 09:16 UTC, Edward Hervey 		committed Details | Review

Description Edward Hervey 2007-03-27 09:16:00 UTC 
Currently, qtdemux doesn't process/handle the 'ctts' atom present in h264 mov/iso files. This means that the outgoing h264 packets are timestamped with dts timestamps instead of pts timestamps.

The outgoing buffers of demuxers should have:
* TIMESTAMP == pts
and if needed:
* OFFSET == dts

Patch follows to fix that behaviour

	Process 'ctts' atoms, which are present in AVC ISO files (.mov files
	with h264 video).
	Use the offset present in 'ctts' to calculate the PTS for each packet
	and set the PTS on outgoing buffers.
	Fixes #423283
