[gst-devel] querry : Caps Negotiation in ffdec_mpeg4

[arnabsamanta]

 Hi ,
	I am running the following pipeline to play elementary mpeg4 video streams.
	filesrc location=../../mpeg4.dat ! queue3 ! ffdec_mpeg4 ! ffmpegcolorspace
! sdlvideosink sync=false

	the filesrc location gives the mpeg4 elemantary streams .
	queue3 is the plug in written by myself which gives the mpeg4 output frame
by frame .
	the frame am giving as the input to this module is of 640*320 framesize.

	when am runnig the pipeline am getting the following error

	ERROR: from element /pipeline0/ffdec_mpeg40: Internal GStreamer error:
