i got video playing on dsp using gst-dsp. I can play sample video from N900 
(called 9.mp4). It plays very smoothly in fullscreen. CPU load is around ~85% 
dsp-load shows ~80%.

If you wonder how to make it working:

You will need armhf debian, e.g.:


You will need to compile kernel with CONFIG_TIDSPBRIDGE=m or wait until i 
upload one.

Follow this:

Compile and install gst-dsp:

Now you can do:

gst-launch filesrc location=/media/card/Documents/9.mp4 ! qtdemux name=demux 
demux.video_00 ! dspvdec ! ffmpegcolorspace ! fbdevsink demux.audio_00 !  
queue ! ffdec_aac ! alsasink

I have problem with audio, maybe the pipeline is wrong. I am new to gstreamer 
so i don't really understand it yet.

Except audio i would like to figure out how to use omapfbsink.
