Hi,
We are facing A/V sync issue in live streaming from a RTP source via Wowza Media Server(v3.1.1 build1479), where sometimes audio(AAC) is ahead/behind video(H264).
AVSyncMethod we are using is senderreport and configured in conf/[application]/Application.xml. Also we have not enabled rtpResyncAudioVideoOnSR property and hence Wowza should sync using first RTCP sender report for video/audio streams.
We have following queries with above configuration set:
-
Does Wowza use the very first Sender Report and ignores all the reports coming after this
-
Or does it use Sender report when it receives first H264 SPS packet, which may not be the very first Sender report
-
Does Wowza expect RTP source to send both Audio and Video sender reports at the same time
-
Is there a minimum number of Audio and Video RTP packets expected in Wowza receive buffer before receiving first RTCP Sender Report
-
After receiving first Sender report how does Wowza media server syncs Audio/Video streams, does it look at RTP timestamps in media packets
Thanks,
Hitesh
