I would expect the behaviour to be this way
Case 1:Container with PTS and DTS
Incoming buffer has both PTS and DTS
Passthrough case
Case 2:Container having only PTS
Incoming buffer has only PTS
Derive DTS from PTS after parsing H264 stream
Case 3:Raw stream but with SEI
Incoming buffer does not have any timestamp
DTS_START=0, and keep incrementing DTS based on framerate obtained in SEI.
Based on picture type and reference frame derive the PTS
Case 4:Raw stream and no SEI
Incoming buffer does not have any timestamp
Assume framerate=25 and set DTS_START=0, and keep incrementing DTS. Based
on picture type and reference frame derive the PTS
