[gst-devel] GStreamer queue issue

[Jason Yang]

Dear all,

I was trying to use GStreamer(0.10.26) to play a mpg file under the latest
version of Ubuntu.

I used:
gst-launch filesrc location=test.mpg ! mpegdemux ! mpeg2dec !
ffmpegcolorspace ! ximagesink

The video can be perfectly played. Then I tried to use queue to make audio
run as the manual of gst-launch told me:
gst-launch filesrc location=test.mpg ! mpegdemux name=demuxer demuxer. !
queue ! mpeg2dec ! ffmpegcolorspace ! ximagesink demuxer. ! queue ! mad !
audioconvert ! audioresample ! alsasink

Then GStreamer told me queue can't link with the decoder, prompting:
WARNING: erroneous pipeline: could not link queue0 to mpeg2dec0.

I wonder why this is not working as the manual said. I suppose it is a
pretty normal way to play video with audio together. Or Could I have done
something wrong to make GStreamer crazy? If I did, please let me know where
I did wrong, so I can make it work.

Thank you very much for all the replies.
