This is not a bug, this is wrong use.

 (a) buffers coming out of filesrc don't have caps set on them. You can force
     caps on them by puttin a capsfilter into the pipeline, like:

     filesrc location=foo !
video/x-raw-yuv,format=\(fourcc\)I420,width=320,height=240 ! sdlvideosink

     It's impossible to recognise raw video or audio data, so you must
     specify the format yourself.

 (b) you will also need to set the blocksize property on filesrc to the 
     correct frame size for the raw YUV frames (115200 in the above case). 
     This will only work if strides and plane offsets match the ones used
     in GStreamer.

 (c) generally it's a bad idea to feed raw YUV/RGB into a pipeline unless
     you _really_ know what you're doing.
