Audio-Video Sync #28

Open dummymailmi opened 10 years ago

Hi..

I am using Example 3 to stream from Nexus 7 to Wowza Server. I am using MediaCodec for encoding audio and video. I am using AUDIO_AAC for audio.

Initially audio-video are in sync. But with time video lags audio and the lag increases. For example, after 20 min the video lags audio by 4 sec.

What is the issue? Can anyone help me to sync audio and video.

Thanks Alan

You might want to look into your Wowza server. What type of available processing power do you have available? Has the server been tweaked according to the Wowza Tuning Guide [http://www.wowza.com/forums/content.php?46]?

Video quality can suffer if the server doesn't have enough resources.
