[gst-devel] wrong horizontal position of dvbsuboverlay if used behind videomixer?

Hi,

since I use the videomixer to implement picture in picture the horizontal
positioning of subtitles via dvbsuboverlay is incorrect when putting it
behind the videomixer.

For example: the video resolution is 720x576 in 16:9 and videomixer makes it
1024x576 (768x576 in 4:3). Subtitles are shown on the left and not centered
because it uses 720 instead 1024.

The position is of course correct when putting it before the videomixer, but
then the subtitles are overlayd by the pip.

Is this a bug?

Thanks,
Thomas
