Xmms and Xine multiple threads!?!??


Everyone, I am using Slack 10 kernel 2.6.7. When I play a video in xine or a song in xmms, the command "ps aux" shows multiple instances of each For example, Xmms shows 4 threads and xine shows like 10 threads!?!? Is this normal? Does anyone elses systems show similar results?

At the mo I'm listening to an audio CD.

$ ps aux

xio 11025 0.1 1.8 21384 11712 pts/0 S+ 19:31 0:00 xmms /mnt/cdrom
xio 11026 0.0 1.8 21384 11712 pts/0 S+ 19:31 0:00 xmms /mnt/cdrom
xio 11027 0.0 1.8 21384 11712 pts/0 S+ 19:31 0:00 xmms /mnt/cdrom
xio 11028 0.0 1.8 21384 11712 pts/0 S+ 19:31 0:00 xmms /mnt/cdrom

The same thing happens when listening to an MP3.

I'm sure someone else can explain why :)

Ask that to xmms team
but processes that use 0.0 % CPU and 1.8 % Memory are not the ones that can hang a system or slow it

Linux isn't multithreaded, so it has to run different processes for parts of an app. Not to worry, it isn't using any more memory as it would otherwise.

noticed something similar the other day when I used alt+tab to change between aps: xmms consisted of three different 'steps' player, equalizer and playlist... add an mp3 codec and an output plug-in .... how many threads would that give you?

Thanks for everyones input..... it sounds linmix is right. Its probably just multithreaded to handle pieces like plugins and playlists.... I just wanted to make sure the same app wasnt being opened 5 times.

Question multiple proc

Hi guys,

I'm running slack 10 since a few days and here's what i've just noticed:


When i'm running dcgui-qt or xmms i have several thread appearing if i do a [ps -ef] command

this is rather annoying my system is very slow for a 2.8ghz with 1g of ram

Aside this if i do a [top] command it mark upthere [CPU(S): blablabla ]

When i was under 9.1 it was marking me { CPU0: bla bla bla } (i have hyperthread)
{ CPU1: bla bla bla }

I took my old .config which was the very good one with all my drivers working and recomp my 2.4.26 kernel as i always do with the hyperthreading support in it...

i suspect some forking problem somewhere but i ain't that good to understand the thing


Any id of what's going on ?

different modules of the same program could be responsible for the appearance of a thread for each: plug-ins, playlist, equaliser, etc. all get 1 thread each.
