Hi,
I'm facing difficulties when trying to stream h.264+AAC SBR to a nokia N96 with gstreamer. I'm not sure if the encoder properties are set correctly in order to be decoded by the n96. I'm using x264 and faac for the encoding process. The rtp payloaders are rtph264pay(RFC 3984) and mpg4gpay(RFC 3640) and the information is transfered using DVB-H - OMA BCAST. This system works with other phones (but not using OMA BCAST). The system using OMA BCAST works with n96 when using another transcaster (h264 basline codec and AAC-HEv2). I tried encoding to file and play it locally on n96 and it worked. Maybe the SDP file is not correct? But VLC is able to stream the video from the sdp file... And it did not work to just stream the video. All help is very much appreciated.

x264 properties:
cabac = false
dct8x8 = false
bframes = 0
b-adapt = false
key-int-max = 10
bitrate = 384
byte-stream = true

faac properties:
bitrate = 38000
profile = LC(2)

the corresponding sdp file is:
