------- Comment #10 from Tim Angus  2007-04-26 14:24 UTC -------
Is this patch known to work? I have applied and compiled it successfully but
I'm not having much luck in using pipelines which require push support. For
example...

gst-launch-0.10 gnomevfssrc location=/home/tim/public_html/whatever.flv !
decodebin ! ffmpegcolorspace ! ximagesink

...works with no problems, but if I put a queue between the source and the
decodebin I get no output window and a lot of ERROR lines in the terminal:

tim at backpack:~/sources/gstreamer/head/gst-ffmpeg$ gst-launch-0.10 -v
gnomevfssrc location=/home/tim/public_html/whatever.flv ! queue ! decodebin !
ffmpegcolorspace ! ximagesink

[snipped lots of output similar to above]
[gst-launch appears to hang at this point, and I hit ctrl-c]
