[gst-devel] How to diagnose the rmvb playing problem

[Ruan Wen]

Thank you!

I run the command
GST_DEBUG="rademux:4,real*:4" gst-launch playbin
uri=file:///home/ruanwen/Desktop/media/04.rmvb

[ruanwen at localhost ~]$ GST_DEBUG="rademux:4,real*:4" gst-launch playbin
uri=file:///home/ruanwen/Desktop/media/04.rmvb
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

The debug shows that it can't handle audio version 10. But how to support
the real audio version 10?
I have added the codec such as amrn.so amrw.so  atrc.so  colorcvt.so
cook.so  drv1.so  drv2.so  drvc.so  raac.so  ralf.so  rv10.so  rv20.so
rv30.so  rv40.so  sipr.so to the /usr/lib/codec and it seem not to work as
before.
