h264 and mp3 over RTP

Hello,

We are using ffmpeg to encode the an incoming tv stream in to h264 and mp3 and stream these transcoded streams over rtp. Please see the sdp file generated below. As you see the audio and video streams come over different ports. I am able to play out this sdp using vlc. However if I use the rtplive example from wowza, only the video plays out. From the documentation as far I can see, both of h264 and mp3 formats are supported over rtp. Am I misunderstanding sth.? I already have the log file during such a playout. I can send it to an email you provide if you like…

Thanks,

We do support H.264 and MP3. The problem is that the audio portion of this SDP file is missing the rtpmap statement. This is required for us to properly connect to the audio stream.

Thanks, that missing map entry is apparently a bug from the ffmeg library. The sdp creation for the aac works alright though.
