Gstreamer lip sync issues

Wowza Streaming Engine
2

I know that people have reported lip sync issues with streams coming from different encoders. The streams will playback fine in VLC directly or even RTSP/RTP through Wowza to VLC but in Flash the lip sync is off. We have not determined what causes the issue. A few things that could contribute:

  • Be sure you have set a NetStream.setBufferTime(secs) value in your player of between 2-5 seconds. If you are using one of our example players for playback you are OK.

  • See step#1 of this forum post:

  • Try turning off B-frames.

  • Be sure the stream has a consistent frame rate (some encoders will change the frame rate on the fly)

  • Try the new Flash player 10.1 beta 2. They have updated the H.264 decoder

    I hope this helps.
