Hello Attila

Post by David MulcahyI am having a performance issue with mplayer using mga_vid in debian
stable. Looking at all the advice online seems to indicate that -vo
xmga will give the best performace. However I have been seeing a slight
jerky picture when the camera starts panning across a room or scenery.
It's actualy a problem of the codec eating more cpu time. When
you have a lot of movement, then the codec needs to access more of
the picture in a way that will most probably destroy all advantage
you get from L2 cache.
Post by David Mulcahy I started adjusting lots
of thinks to rectify this (hdparm upgrading kernel and debian to
unstable, tweaking things) but what seems to work best is the following
command.
mplayer -ao alsa -channels 2 -vo xv -dr -double -dvd-device /dev/cdrom dvd://1
For me, using -cache 10000 mostly solves these issues.
This makes it slightly better for the .1% of the times that this blur is
happening. Again 99.9% of the time it is great.
Post by Attila KinaliIf it's not related to cpu usage (have a look at the "suposedly droped
frames" counter), then -mc & co might be of use.
Post by David MulcahyI guess the question is why this works better because direct rendering is
(as far as i know) is more likely to work with xmga than xv, but in my
case it works with xv and again as far as i can tell doesnt work with
xmga.
Hm.. dr is some kind of black magic. It only works in very special
cases and is silently disabled in all other. I haven't checked
the code myself so i cannot say whether mga should perform better or
not.
Just BTW: If you have a dual cpu machine, Xv will actualy give you better
performance than mga (around 20% or so) as it splits the load onto two
programs which are then able to use both cpus
I wish I had a dual cpu.
Post by Attila KinaliPost by David MulcahyNow i thought I best check with the experts to see if I am in fact using
the best settings because I have a feeling that -vo xmga -dr should work
and give me better performance. Am I right or do am I using the best way
with -vo xv -dr.
I'd need a -v log at least be able to say anything.
