Netwalker Video Performance And Audio Problems.

[ptoki]

As I discovered netwalker is quite powerful device and can play full screen video smoothly.
Details are here:

In short. After dumping pulseaudio totem player and vlc player started to play video smoothly. But there is a problem:
Video is played too fast.
I dod not have enough time to find out why and how to fix this.
Maybe it has something in common with cpu governor and constant switching between 160MHz and 800MHz?
I have written a nifty script to wisualize how cpu is switched and it shows that in normal conditions cpu can be switched 2-5 times per second between 160 and 800MHz and stays in higher clock for 5-20% of time. Maybe players got confused by this?
I will check this soon...

Any way. It is nice to be here again

Recipe to make video playback acceptable:

Put debian-multimedia.org in /etc/apt/sources.list
deb http://debian-multimedia.org stable main

Change jaunty to karmic in the same file for ports.ubuntu.org

Install mplayer and kmplayer (to have gui) from aptitude (or any other method is
acceptable)

Run kmplayer, load movie and watch

Performance:
playing in window in native movie resolution (720x300something) is smooth even
in fast scenes. Playing in full screen is smooth but a bit chopping can be
noticed (i would say 15-20fps).
Video shutters when changing to another application and it takes a few seconds
to back to smoth play after focusing kmplayer.

During playback cpu is all time in fast mode.

I did not tried to solve sound problems with totem-player. But I will try...

I'd suggest to remove karmic repo after this. Last time I tried to migrate to karmic I had to restore whole OS after attempt to upgrade libc version.
