Thanks for your response. I will give the newer version of gst-ffmpeg a try (I hope building it isn't too much of a headache and that it will be binary compatible). I also looked at the DShow decoder wrapper, but somehow cannot instantiate it. I tried the following code: GstElement* videoDecodebin = gst_element_factory_make ("dshowdecwrapper", "videodecodebin"); This always gives me a null object. I know I have the bad plugins installed and gst-inspect does give me some reasonable output. Any thoughts on what I might be missing? The documentation is pretty light on this one but from what I could tell based on the output from gst-inspect and the source code itself, it doesn't look like this will actually work with VC1 (aka WMV9 AP, fourCC: WVC1). I am assuming that this is because I am not using the latest version from CVS, correct? Or am I missing something?

They will provide VC1 support (amongst other formats).    Edward On Fri, 2008-03-28 at 16:42 -0500, Andreas Schuler wrote: > Hi all, > > I am currently evaluating GStreamer for a project I am working on.
