[linux-dvb] Re: [Mplayer-dvb] mplayer playback through dvb takes100% cpu time

[Dirk <dirk-mailinglisten@wor.net>]

I don't know the exact difference beteween PS and TS, but it happens 
with every file that I tries so far:

- mplayer ... dvd://1
- mplayer ... test-divx.avi
- mplayer ... test-xvid.avi
- mplayer ... test.mpg (recorded by buffer < /dev/dvb/adapter0/dvr0 > 
test.mpg)  - this is TS, I think
- mplayer ... test.cpy.avi (recoded from test.mpg by mencoder -ovc copy 
-oac copy ...) - this is PS?

I have not yet tried other mpg-Files.

Maybe it is interesting that xosview shows most of the used CPU time as 
"SYS" (red bar) when
using -ao oss/alsa9/null. The "blue" part is about the amount I would 
expect (depening on the file
type played).
