Hi, gstreamer-devel:     We have the same problem -- we use decodebin to play the rtsp movies. If I use:     gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! decodebin ! ffmpegcolorspace ! xvimagesink d. ! decodebin ! audioconvert ! alsasink     We got the same error info: not linked (-1)     If I didn't use decodebin instead of using depay & decoder, everything works well, e.g:     gst-launch rtspsrc location="rtsp://xxxxxx" name=d d. ! rtph263pdepay ! ffdec_h263 ! ffmpegcolorspace ! xvimagesink d. ! rtpamrdepay ! amrnbdec ! audioconvert ! alsasink     P.S: The not-linked(-1) error occurs when using decodebin doesn't happen every time. Sometimes the decodebin works well. So, Is this a bug of decodebin?
