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:
negotiation problem.  Please file a bug at
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer.
        Additional debug info:
        gstffmpegdec.c(1981): gst_ffmpegdec_chain (): /pipeline0/ffdec_mpeg40:

        the capability of the queue3 srcpad is "ANY"
        the capabilty of the sink pad is

                 height: [ 16, 4096 ]
              framerate: [ 0/1, 2147483647/1 ]




        Can some body tell me how can i solve  this error ?
        do i need to change the capability of the queue3 element or of ffdec_mpeg4
?

 Thanks and Regards,
        ~Arnab.

       the frame am giving as the input to this module is of 640*320 framesize.

This is just a stab in the dark, but 640x320 seems like a weird framesize - you sure it's not 640x480?
