[gst-devel] Change Framerate of recorded stream

[Wes Miller]

Rob,

Well, it looks like a good start, but it doesn't quite work.  Any
suggestions based on the following?

As written (with filename fixes):
     gst-launch-0.10      gnlfilesource duration=10000000000000   \
                                  media-duration=100000000000  \
                                  location="file:///c:/gstreamer/bin/2.mkv"
\
                               ! autovideosink

I get:

     Setting pipeline to PAUSED ...
     Pipeline is PREROLLING ...
     ERROR: from element
/GstPipeline:pipeline0/GnlFileSource:gnlfilesource0: Could not perform
      seek on resource.
     Additional debug info:

     ERROR: pipeline doesn't want to preroll.

If I replace autovideosink with fakesink -v I get:
