Dear all,<br>
<br>
I was trying to use GStreamer(0.10.26) to play a mpg file under the latest<br>
version of Ubuntu.<br>
<br>
I used:<br>
gst-launch filesrc location=test.mpg ! mpegdemux ! mpeg2dec !<br>
ffmpegcolorspace ! ximagesink<br>
<br>
The video can be perfectly played. Then I tried to use queue to make audio<br>
run as the manual of gst-launch told me:<br>
gst-launch filesrc location=test.mpg ! mpegdemux name=demuxer demuxer. !<br>
queue ! mpeg2dec ! ffmpegcolorspace ! ximagesink demuxer. ! queue ! mad !<br>
audioconvert ! audioresample ! alsasink<br>
<br>
Then GStreamer told me queue can't link with the decoder, prompting:<br>
WARNING: erroneous pipeline: could not link queue0 to mpeg2dec0.<br>
<br>
I wonder why this is not working as the manual said. I suppose it is a<br>
pretty normal way to play video with audio together. Or Could I have done<br>
something wrong to make GStreamer crazy? If I did, please let me know where<br>
I did wrong, so I can make it work.<br>
<br>
Thank you very much for all the replies.<br>
