[gst-devel] Porting ASF demuxer to 0.9

[Amit Bhalla]

Hi,

I think I am fairly close to having something functional.  I am
encountering an error from ffmpeg decoder.  The error message states
that the input format has not been set.  I took a look at ffmpegdec.c
in -base.  There is an 'opened" flag that I'm not sure gets enabled. 
Comparing the asfdemuxer to the avidemuxer (which works) does not show
much difference outside the fact that avidemux relies on the riff
library.

I've copied a snippet of the debug output.

Thanks for any enlightenment.

Cheers,

-Amit
