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

[PERET Pierre-Hugues]

As i can stream a mp4 + AAC file from vlc+DSS to QTplayer on windows, i 
don't know why i cannot play it on the mobile phone, maybe it's a player 
issue (Realplayer) .
Helix player can be recompiled with mpeg4 support (i'm not able at this 
time to do this). But if someone can compile helix player with mpeg4 
support for symbian OS, i would be glad to test it, but it think AAC cannot 
be streamed with mpeg4 in rtsp or http, anyone can confirm this ?

if i have time, i will recompile vlc with samr support. but it will not be 
until next week.
