[gst-devel] Error whiling playing video

[Eric Zhang]

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?
