[gst-devel] MPEG video format

I am having a problem with the output video aspect ratio from mpeg2dec.

A sample that illustrates the problem is available at
http://www.w6rz.net/parkrun1280_18mbps.ts.,
although it also happens on live DVB streams.

The video is supposed to be 1920x1080, but during caps negotiation, it
is offered as 1280x1080.
The header appears to have 1280x1080, but aspect code 3, which is 16:9.

The result is that after scaling the picture appears roughly 5:4, rather
than 16:9.

Should the mpeg decoder be putting out the 1920x1080 caps, or should the
other elements of the
stream be looking at some other caps?
