No video playback, only audio.

[mhsw0409]

Hi guys, I've looked around the forum for someone with a similar problem, but I found nothing. I recently installed Fedora 13 in my laptop, installed the audio codecs(mp3..and etc) and worked just like a dream. But every time I try to play a mpeg, avi, mov file in a player (vlc, xine, mplayer) I get no video, just a black screen. But I get the audio from the video. Any ideas?


thanks.

Hi,

Regarding mplayer, it ships with video output set by default to VDPAU. If you don't have an nVidia card + nv driver, you end up with black screen. For mplayer, check the video settings in the GUI. "xv" is a reasonable choice for non-VDPAU users.

WWell,

Hello
sorry about the delay, well everything looks ok in that file, a normal avi, divx vid and mp3 audio.
Do you have gstreamer plugins bad and ugly installed ? they're available from rpmfusion, they should be all you need
You could try a different video driver, if you type

mplayer -vo help

you should see a list of available drivers, the first I'd try is x11 like this

mplayer -vo x11 ~/video.avi

one last thing, you haven't mentioned using ffplay which can only be done from the command line, seems to work when all else fails

[mhsw0409]

Code:

mplayer -vo x11 ~/video.avi

Okay, that worked. But how can I manage to use that codec on vlc? And yes, I have gstreamer ugly and bad installed.

Hi,

"-vo x11" is not a codec. It defines which video output to use. On Linux you can use multiple "paths" to push the video to the screen: VDPAU (for nv driver and nVidia cards), xv (for most cards/driver which support the Xv extension of X Window system), SDL (for systems which have proper OpenGL support), x11 (a fail-safe if nothing better works).

On most modern video cards at least "xv" works properly. Try "mplayer -vo xv video.avi". If it works, chose "xv" as default output in teh Mplayer GUI (probably same for VLC). If not, come back here with the output of "lspci" to try and figure out what video card you have and which driver is used.

WWell,

Hello
the quick answer is click on the yellow fedora set-up guides at the top of this page and install autoten.
vlc has most of what you need built in as does mplayer both of which are excellent media players

no more windows user

welcome to the real world
