mplayer displays blue and green lines on edges


For some reason, videos in mplayer all show up with a blue vertical line on the very left edge of the video window. Also, in full screen mode, I also get a sort of greenish line along the bottom edge. Any idea why this happens? Is there maybe a way I can offset the video within the video by a pixel or two to cover up these lines? Here's the relevant specs I can think of:

distro: Fedora Core 4
desktop system: gnome (2.10, I think. whatever is on FC4)
mplayer version: 1.0pre6-3.3.3

Let me know if you need any more info, or want me to run a few tests, diagnostics, whatever. Any help would be greatly appreciated, since while videos are still viewable, this is a huge annoyance. Thanks.

It is easy to crop the picture before display with option -vop crop=w:h:x:y, where you just use the width, height and xy coords of top left corner you want to crop to.

To track down the source of the problem (assuming it is not present in the video itself) you could try different video-out options on mplayer (mplayer -vo help will show what is available) or try another player such as xine or vlc (www.videolan.org).

It's definitely not the video or the video format either, since it happens with a bunch of different ones with different formats (mpeg, mov, wmv). Apparently it's a driver problem as well, which isn't too surprising. Linux has always had a problem or two with my video card (Trident cyberalladin something something). So, x11 gets rid of the lines, but now when I try to change the video size at all or go to full screen, the window changes size but the video doesn't change along with it. Any ideas on how to fix that?

Also, I'll look into xine and vlc. I've had some problems with xine a while back, but maybe I'll give it another shot. Any idea if either of those have plugins for firefox?

Edit: Also, the blue line there is, as far as I can tell, part of some sort of default blue background for X windows or gnome or something like that (I can see more of it if I move around the video window fast while the video is playing). Is there a way I could just change that color to black? It's more of a workaround than a fix, but I could live with that.

As explained in the docs

http://mplayerhq.hu/DOCS/HTML/en/video.html

the options -fs -zoom (both together) give full screen with -vo x11. Apparently this is quite slow, although seems OK on a 2.4GHz P4. The above link has lots of other useful information on the different -vo options, as well as some Trident specific notes.

Wow, thanks, looks like that should really help. I'll give that a shot later on when I've got some time. Guess I've got to learn to RTFM. But thanks for the help, I appreciate it.
