Dear Wowza team,
we use a FMLE3.2 to encode and stream a H.264 livestream to a Wowza Media Server V3.6.2.
The Wowza Server Application is configured as live-record and automatically records the stream data into mp4 files.
In this scenario we have the issue, that audio data is sometimes missing during the last seconds of a recorded mp4 file.
More precisely, we have a continuos video stream as an input signal to the Flash Media Encoder.
The internet connection on client-side is not the best with 500kb/s (T-Com), but it seems to be stable.
After a random time Wowza starts to record a new file although we did not stop and restart the streaming on FMLE side.
In this discontinued file the audio seems to be missing during the last 7 seconds although the video is still be shown.
You can find an example here: http://www.dresden.de/de/02/030/stadtratssitzung-live3.php
My colleague has the idea that it might be an out-of-sync issue where the gap between audio and video data gets too high so that it still shows the buffered video-data whereas the audio data is missing and then starts a new publishing of the resnyced stream. Could this be the case or is that unlikely? What can we do to prevent this behavior?
I thought of something like http://www.streaminglearningcenter.com/blogs/48-khz-audio-can-cause-loss-of-synch-with-flash-playback.html, but this doesn’t seem to be the case.
Configuration is as follows
Thanks in advance
