PCMU depacketizer and packetizer
The stream coming into my media server is H264 + PCMU over RTSP.
Wowza drops the audio track because it doesnt know how to depacketize PCMU from the RTSP stream (warning reported: "Failed to find an appropriate depacketizer for this track (PCMU)").
However I know that for the same stream (H264 + PCMU) coming into the media server over RTMP, the audio track is not dropped, and can reach a RTMP client without any problem.
Similarly, if the stream comes in the media server over RTMP, but a client request the stream over RTSP, wowza drops the audio because it doesnt know how to packetize PCMU for RTSP (warning reported: "RTPPlayer.describe: No audio packetizer: G711_MULAW").
Why is that? Why can Wowza handle the same content fine over RTMP but not with RTSP?
