RTSP restream transcode the audio only
Posted: 25 Feb 2011 10:30
Hi,
I am trying to restream the rtsp output from Wowza which uses MP3 encoding the audio to DSS.
and I'm wondering how do I transcode the audio codec to mp4a without changing the video part.
For now I have tried command line like below
It uses just the same video codec H264 as the input stream but the quality of output stream is awful.
Thanks!
