Description Stirling Westrup 2013-01-11 22:48:37 UTC 
I've discovered an easily-reproducible case where videoconvert is taking a caps with a pixel-aspect-ratio of (fraction)[ 1/2147483647, 2147483647/1] and choosing 1/2147483647 for its (arbitrary) value, rather than something sane like 1/1

Arguably in this case the source should probably be providing a solid aspect ratio, rather than a range, but I think that is a separate bug.

The command line that caused this was:

gst-launch-1.0 ximagesrc display-name=":1" ! videoconvert ! xvimagesink display=":2"

In case this doesn't behave the same for other folks, here's a link to a full log of an attempted run:

The bug is here is that ximagesrc didn't set the aspect ratio correctly.

It's fixed now:

    ximagesrc: Set the pixel aspect ratio correctly in the caps

Should also be in 1.0.6
