Bandwidth-Efficient Mode for AMR/AMR-WB

[Samer Al Hakim]

Hello to all members,

Using GStreamer, I would like to create two RTP ends that that are capable of sending and receiving RTP audio streams in AMR/AMR-WB codecs. I already checked and tested the available GStreamer elements (rtpamrpay and rtpamrdepay). They seem fine but I was surprised to find out these elements only support the AMR/AMR-WB codecs in octet-align mode. But for my application I definitely need the mentioned codecs in bandwidth-efficient mode.

The differences between these 2 modes can be found in the respective RFC 3267:

http://www.ietf.org/rfc/rfc3267.txt

I was wondering if there are other GStreamer elements that support the bandwidth-efficient mode? Or perhaps someone has already some examples or prototype elements?

Thanks & regards,
Samer Al Hakim
