[streaming] Re: Streaming mp4+AAC to mobile phones

[PERET Pierre-Hugues]

Well,
back again !
streaming amr_wb is the same as amr_nb.. it doesn't play in QTplayer 
because it doesn't have the codecs, but the mobile player seems to accept 
it, but no sound is coming.
switch back to amr_nb and play with the sdp file....
