I have WowzaServer Developer Edition installed on a linux server. My project is to record and automatically post the video on YouTube. (Using the YouTube API).
Using the application "Recording " which brings Wowza (the sample application as an example), record and save a file. FLV without problem.
When playing or downloading this file you can see the recorded video correctly (no synchronization problem.) But to post it on youtube to upload api or “manually” to YouTube, the sync problem occurs between audio and video.
At first I thought the time was constant sync. Then I saw it was a problem that occurred when there was a silence at the time of recording (in user pc).
For this to make “setSilenceLevel = 0” had been solved. Despite this, on Mac and some PC is still giving this problem.
The strange thing is that when downloading the video recorded on any machine, is displayed with correct timing.
I tried many things. Reformat the record. Search sync time average and corrected through ffmpeg. Set in Application.xml times to sync. Other tries.
This can be corrected?
if some of the codecs of the client, how to unify and / or correct this?
can independently record audio and video (and then join with ffmpeg)?
