I have an RTSP stream from a camera in this URL: rtsp://220.127.116.11:88/live/h264_ulaw This streams the video in h.264 encoder and the audio as mu law 8000 Hz PCM. If I use VLC I can see and hear well. Also, while watching the stream when Wowza restream it to a flash client everything seems fine. However, I use an rtp-record type of stream, and the result recorded file has bad Audio track. Video is fine, but it seems to get the audio as APDCM with 54000 Hz.
