I've been playing with the lowres feature that some decoders in ffmpeg provide.

In particular I've been playing with the ffdec_mpeg2video and I noticed that
the size specified in the srcpad wasn't downscaled. 

It produces 2/4 copies of the image and sometimes a segfault.

I've been testing it withe the following pipeline:

gst-launch-0.10 -v filesrc location=chickenpayback.mpeg ! flupsdemux !
mpegvideoparse ! ffdec_mpeg2video lowres=1 ! queue ! xvimagesink
