xorg log

Hi. Please see attached screenshot and xorg log. When I crop/zoom to 16:9 in VLC, the left hand edge does not update, but the rest is OK. So the picture is actually 16:9, but some of the left edge is missing. It looks to be the same amount as the difference between full width and the cropped version.

Not sure if this is a VLC or radeon bug. But I asked in freenode/#radeon and was advised to file this bug.

Do any other movie players exhibit this problem?  What does VLC's "cropping" do?  You might also try xf86-video-ati from git master there are some Xv changes there that are not in the 6.12-branch.

No, only VLC has this badness. xine & *mplayer are fine. The cropping crops the edges and resizes the image to fit into a 16:9 "box" in both original player and fullscreen. As I say this might be a VLC bug, but it doesn't do that with the i810 or intel drivers, which I also tested on similar setups.

vlc may use src clipping which may be broken in 6.12.x.  Can you try with xf86-video-ati from git master?

Thanks.

I pulled the git xf86-video-ati master, and it seems to have cured the badness.

I made a couple of extra screenshots to show this. They are from the same frame as the previous VLC screenshot attachment.

Should I now close off this bug report, since it looks like it's been dealt with ?

fixed in master.
