When you stream audio over live-555's RTSP plugin on mplayer, what decides the audio data to be big endian vs little endian? I am developing a server and I am specifying the format as 97 (dynamic format) with rtpmap being : 96 L16/8000
for single channel, 16 bit/sample, 8 khz sample rate audio. But mplayer somehow thinks audio data is in big endian format and attaches a BE -> LE conversion filter: after getting "describe": Initiated "audio/L16" RTP subsession on port 4770 .... ... after getting "play" command: Building audio filter chain for 8000Hz/1ch/s16be -> 0Hz/0ch/??...

The data originally is in little endian format. When I overwrite the stream type to be s16le in mplayer's libmpdemux code, it plays but it repeats a section over and over again. If anybody could help, I would appreciate it. Thanks! Ratin
