Hi all,I have a laptope witn a pentium III processor a 600 MHz With 128 Mo of memory.
The problem with this computer is that when i want to play divx, the sound is n ot play at the same time with the video. I use Mplayer. I don't understand cause on dreamlinux, divx works perfectly. Maybe i have a problem of configuration but i don't know wich one.
If you've got an idea...
Thank you^^

I use the mplayer in the uci section of mydsl optionals. I copied the config file from the /opt/mplayer... dir in /home/dsl/.mplayer/ and inserted this line in the file config :framedrop=yes
legalize cannabis, etc.

If your movie is playing from a cd rom, you might get better performance by enabling dma for that drive:sudo hdparm -d1 /dev/cdrom

i play the divx from the HDD, and i already active the DMA for it ^^(maybe it's not a good idea, i don't know^^)
Thanks to you^^

Are you using video acceleration? If not, it's worth a shot. (How is your dreamlinux's X set up like?)

I didn't install the graphic driver on DSL. I have a SM 721 (Lynx3DM; 4MB).But i don't know how to install it.
Have you got an idea?
Thanks a lot

Try the "siliconmotion" driver maybe... < http://www.xfree86.org/4.3.0/siliconmotion.4.html >SM720 seems to be the similar to the SM721 from looking around...

If you run mplayer from the commandline (the best way to run it) it will print out some tips if playback is too slow, includingturning on framedropping (as mentioned)
setting -cache 8192 (if you are playing from slow media eg dvd/cdrom)
-autosync 30
and some others I can't recall.
Try playing it back smaller eg mplayer -xy 0.5 will half the resolution
Slow video playback can be caused by a buggy sound driver as well.
Getting graphics acceleration going is obviously the best thing, but with a processor 3x as fast as yours, dsl dma toram can get by without it (except for action movies or 3d games).

Hi:) I run mplayer in a terminal and i see tqo stranges things:
"Detected cache-line size is 32 bytes" (i have a PIII with 256 Ko of cash memory) Maybe i do a mistake and this size is not what i think^^
The most important is "MMX2 supported but disabled"
"MMX:1 MMX2:0 SSE:1 SSE2:2"
Esxcept this everything looks great^^
I don't understand why i don't have my MMX2 activate.
If you've got an idea^^
Thanks a lot.

Hello,If you are using the mplayer.uci from mydsl>testing, the problem was due to mplayer being compiled with '--disable-rtc'. The problem appears even on this build machine, a pentium 4. Just submitted a recompiled mplayer a few days ago and it has been uploaded to 'Testing'. So, this synch issue is now fixed.
('rtc': the computer's real-time clock provides an accurate time source to keep the video and audio playing together. '--disable-rtc' made it depend on *gaba gaba* some software technique which loses accuracy as the movie progresses, so video falls more and more behind sound.)
