rtppcmadepay2

Extracts A-law encoded audio from RTP packets as per RFC 3551.

Example pipeline

 gst-launch-1.0 udpsrc caps='application/x-rtp, media=audio, clock-rate=8000, payload=8' ! rtpjitterbuffer latency=50 ! rtppcmadepay2 ! alawdec ! audioconvert ! audioresample ! autoaudiosink

This will depayload an incoming RTP A-law audio stream. You can use the rtppcmapay2 and alawenc elements to create such an RTP stream.
