[MPlayer-dev-eng] playing little endian format uncompressed PCM audio stream via RTSP

[Ratin]

When you stream audio over live555's component on mplayer, what decides the
audio data to be big endian vs little endian? 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:

I hear nothing but noise. The data is in little endian format.
