Hello... has anyone here ever had synchronized video and audio on a video conferencing application.. Thanx :). I created a video conferencing application .. well I wasn't able to get the video and audio on good sychronization and the audio has an echo when transmitted.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I am using H.263 or JPEG for video and G.711, GSM mono , G.723 mono for audio.. I was trying these formats for some time now and I wasn't able to get it synchronized. Do you have any suggestions to have a synchronized conferencing application.. Thanks..

Are you streaming using RTP/UDP or over some kind of TCP connection? For RTP, you need RTCP packets being sent to give the base time. Also, the timestamps for the video and audio packets need to be synchronized at the source; otherwise, it will be impossible to synchronize them.

Are you using FOBS4JMF and are you using RTP? What kind encodings are you using for the audio and video?
