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
