How Should Rtp Sessions Be Played Back? |
|
Answer» SINCE RTCP packets contain absolute time information, a recorded session cannot SIMPLY be played back by time-shifting the whole recorded session. ONE approach plays back the data packets with their original time stamps, with re-normalized timing. SDES information other than NOTE items can be gathered for each source and REGENERATED as in a "live" session. NOTE SDES items need to be inserted at the APPROPRIATE instant in the playback as they are allowed to change.
