Hi guys,
I'm using the following pipeline for send a stream to the media server Wowza. gst-launch-0.10 -v v4l2src device=/dev/video1 ! "video/x-raw-yuv, format=(fourcc)YUY2, width=(int)640, height=(int)480, framerate=(fraction)30/1" ! queue ! videorate ! "video/x-raw-yuv, format=(fourcc)YUY2, width=(int)640, height=(int)480, framerate=(fraction)25/1" ! queue ! ffmpegcolorspace ! "video/x-raw-yuv, format=(fourcc)I420, framerate=(fraction)25/1, width=(int)640, height=(int)480" ! queue ! x264enc bitrate=500 ! queue ! rtph264pay ! queue ! udpsink host=192.168.0.230 port=8000 sync=true alsasrc ! "audio/x-raw-int, endianness=(int)1234, signed=(boolean)true, width=(int)16, depth=(int)16, rate=(int)48000, channels=(int)2" ! queue ! faac ! queue ! rtpmp4gpay ! udpsink host=192.168.0.230 port=8002 sync=true I'm not exactly sure about the problem but the final stream (after going thought Wowza) have a lip sync delay of about half a second. I don't know if a problem on my pipeline or is a Wowza problem. Do you know if there is any kind of incompatibility between GStreamer and Wowza?

Do you > know if there is any kind of incompatibility between GStreamer and Wowza? There is not. Maybe your sdp file does not use a 48000 hz rate ?
