I am currently trying to take the SDI source from a Black Magic Decklink card and send it to WOWZA for streaming, and eventually transcoding once I get the streaming working. I am using Gstreamer and Decklinksrc to capture the incoming audio and video. Im new to Gstreamer, but by walking through the docs, and some internet scouring I have gotten to the following cmd line...

gst-launch-0.10 decklinksrc mode=11 connection=0 audio-input=1 ! ffmpegcolorspace ! "video/x-raw-yuv, format=(fourcc)UYVY, width=(int)1920, height=(int)1080, framerate=(fraction)30000/1001" ! ffmpegcolorspace ! x264enc tune=zerolatency ! video/x-h264, profile=main, framerate=30000/1001 ! flvmux ! rtmpsink location="rtmp://"

Can anyone assist in getting the audio into the outbound RTMP stream, or point me to the correct demo/tutorial that I will help with this?
