Hi,

reverse playback is not working with videotestsrc :
- Reproduced on 0.10 SDK and 1.0 HEAD
- Working fine with audiotestsrc

audiotestsrc and videotestsrc are both used for gap on Gstreamer Editing
Services. So with this issue not reverse playback can be done on timeline with
gaps.


In attachement a simple program showing the issue on videotestsrc and showing
that it is working fine on videotestsrc.

For 1.0, you will have to change  

if (!gst_element_query_position (GST_ELEMENT (pipeline), &format, &position)) {

to

if (!gst_element_query_position (GST_ELEMENT (pipeline), format, &position)) {
