Also why does the first few seconds of each video stutter?

It eats huge amounts of RAM, causing stalls when huge amounts of unused pages get swapped out.

hey so i played aroud with the streaming of the internal player and this is what i got so far:

i installed "Decoders Support 0.1" from extras-testing
and then i setup vlc on my computer to stream a movie with this

:sout=#transcode{vcodec=mp2v,vb=100,scale=1,width= 800,height=640,acodec=mpga,ab=128,channels=2,sampl erate=44100}:std{access=http,mux=ts,dst=0.0.0.0:80 80}

then i got on my n900 and went to a site where i uploaded a video.m3u that contained http://192.168.1.130:8080 and that tricked the internal player to pickup the mpeg2 stream and start buffering

now the quality was not something to be proud of but it worked! with a bit of lag

but one thing that stroke my mind was.... is the DSP in use?
so i did a top and this is the results

Mem: 240648K used, 4900K free, 0K shrd, 244K buff, 43136K cached
CPU: 73.7% usr 14.8% sys 0.0% nice 9.4% idle 0.3% io 0.0% irq 1.4% softirq
Load average: 2.61 2.54 1.88
PID PPID USER STAT RSS %MEM %CPU COMMAND
5258 659 user S < 31364 12.7 42.8 /usr/bin/mafw-dbus-wrapper mafw-gst-renderer
785 659 root R < 19540 7.9 21.1 /usr/bin/Xorg -logfile /tmp/Xorg.0.log -logverbose 1 -nolisten tcp -noreset -s 0
734 1 pulse S < 3676 1.4 17.4 /usr/bin/pulseaudio --system --high-priority

I havent figured out how to minimize the stream so i can check the preformance on browser, widgets ect.
but from what i can see from the top there is no cpu left to that

There already is a great solution for watching streaming vids from your PC/media-server!

There is no mpeg2 dsp decoder provided by Nokia on the N900. However there are dsp implementations on the OMAP3 for MPEG2.

I put the stock flumotion in extras-devel. There is still a bit of work for it to stream something useful from the device but we at least have a package available.
