View Full Version : [PPC] Video Playback Problems

June 6th, 2010, 04:12 PM
Hi All

Have just installed Lucid Lynx on my Mac (a 1.42Ghz PPC Mac Mini w/ 1Gb Ram) with a view to using it for stop motion animation and video editing which i intend to do at DV Resolution.

Having got the audio working i'm having a problem with video playback. In Movie Player, video files will only play every few frames and crashes if full screen is clicked upon. Audio Files play back fine. VLC doesn't work at all with any files.

I have installed codecs via software centre.

Does anyone have any suggestions / solutions.

Yeesh, sounds ugly. Do me a favor, try booting with video=radeonfb radeon.modeset=0. tell me if that helps.

I'm sorry, I wasn't terribly clear. You are going to need to use

sudo gedit /etc/yaboot.conf

edit the append section so that it reads

quiet splash videon=radeonfb radeon.modeset=0

Save that, then code

sudo ybin -v

Then reboot and see if that works.

The videos from my camera are mp4 by default... And when I try to view them thru my computer playback programs they run choppy and slow. Too slow to view at all... Other videos/movies I have downloaded that are mp4 however,

Hi sha.goyjo
Thanks for the help. (especially the 2nd post, i know nothing of Linux!)

So, since following your instructions. DV playback is much better. (tho audio has gone again) Resizing by corner dragging is fine but attempting fullscreen by either menu or f11 key results in a crash.
What would be my next step?

Okay, that very first step was due to the fact that kernel modesetting support on powerpc is all but broken. It just doesn't work very well. I wish linuxopjemac was here, he's much better at video issues on powerpc than I am. If he shows up, take his advice over mine on this one.

Try this for your /etc/xorg.conf

# xorg.conf (X.Org X Window System server configuration file)
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
# Note that some configuration settings that could be done previously
# in this file, now are automatically configured by the server and settings
# here are ignored.
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
# sudo dpkg-reconfigure -phigh xserver-xorg
