Sound, but no video from any app


when playing any type of video or a video dvd on my system, there is no picture! I have good sound, just no video.

This occurs in any video app, too; xine, mplayer, you name it.

For reference, I have a Radeon 8500 with a 3D driver provided by ATI.

TIA

Try it with the free radeon driver. Try it with ogg/theora video file.

Show output of mplayer run from CLI.

You've had these systems a while now, did you only just notice this?

OK, where can I get the free radeon driver? I have about 2 dozen repos in smart and sifted around through them but I obviously am lacking the one I need.

I am very suspicious of my video driver, so I'll give it a whirl with the new driver before I collect and post a verbose output.

The radeon driver is included in the kernel. Just put "radeon" instead of "fglrx" in the driver option. man radeon

It turns out I was mistaken. I have been using the kernel driver, so I downloaded and installed the RPM of the ATI prop. driver. A quick double-click of my wedding video yielded sound but no video. I ran it from the cli and got this:

Two things occur to me immediately:
1. use a different video-out device ("-vo xv" say)
2. have you installed the codecs?

Try it with an ogg/theora file.
(install ffmpeg2theora - via yast - and convert an mpeg)

Well, it has been doing this for quite a while. I have been in the Windows world lately to use AutoCAD and haven't pursued it until now. I'm not sure, but it could have stopped working when I pulled out my Geforce 440 MX and replaced it with the Radeon 8500 to increase my 3D performance in Windows. I may try switching my video cards back to see if that remedies it, but then NFS Carbon will no longer play (EA specifically says that NFS Carbon won't run on any GF MX card).

If you used the manufacturer's installer (for the proprietary drivers, off their website) each time, then that could be the problem - though swapping the cards back may not help. If you installed the drivers from repositories (i.e. via YaST) then this is not expected to do anything.

However: I was talking about the software video-out device. The letters that go after the "-vo" flag.

mplayer -vo xv filename.mpg

I still think you should try:

ffmpeg2theora filename.mpg
mplayer filename.ogg

ATI's installer crapped out during decompression. I had to use the RPM on ATI's web site and installed it using smart.

Code:
mplayer -vo xv filename.mpg
netted me the same result; no picture.

I can't find ffmpeg2theora in any of my repos or on rpm.pbone.net. Where do I get it?

Yes... but it should have produced some output. What about using -vo x11?

Darn ... I always just managed "sudo aptitude install ffmpeg2theora" or "sudo yum install ffmpeg2theora" ... looks like you should go to

http://www.theora.org/downloads/

Hmmm... there are "issues" using the official ATI and nvidia installers in Xorg. They have been known to break an X server in unpredictable ways, especially when you change video cards between the two companies. Changing back makes it even more broken.

You should always use the official package for your distribution.

I'll hope that this isn't it: there is no easy fix.

Do you get video by (temorarily of course) switching the video driver to Vesa? Does this happen in VLC as well?

Well, smack my big ears and call me Mickey!

On a whim I changed my display from 1024x768 to 1280x1024 and it started working perfectly.

Explain that one to me!!!

It'll be something in the video mode or in the encoding settings... I'll have to remember this one.
