Make sure you've got an SSH access to the N900
- For USB networking, see this page
Install gst-dsp and dsp-tools
- Get the RPM's from MeeGo Core repository
- on N900: rpm -i <pkg.rpm>
Install gst-omapfb from devel:devices:n900
- Go to download.meego.com and download gst-omapfb RPM package
- on N900: rpm -i <pkg.rpm>
Get TI DSP binaries
- The binaries can be found from Google Code
Copy the DSP binaries into N900 under /lib/dsp
- on N900: mkdir -p /lib/dsp
- on the folder with the unpacked binaries: scp * root@192.168.2.15:/lib/dsp
Verify that the DSP codecs work on the device
- (As root) Load the mailbox_mach module: modprobe mailbox_mach
- (As root) Load the bridgedriver module: modprobe bridgedriver base_img=/lib/dsp/baseimage.dof
- Test that the binaries work by running dsp-test on the device. If the binaries work, it should return copied 1000 times successfully
Test video playback
- Have a video clip with an MPEG4, DivX, XVid, 3ivc, H.263 or H.264 video stream in it.
- Try e.g. this clip
- (If logged in as root, cp /home/meego/.Xauthority /root)
- export DISPLAY=:0.0 && xhost +
- Test video playback with a video-only pipeline: gst-launch-0.10 filesrc location=<file> ! <demux> ! queue ! dspvdec ! omapfbsink
- For MP4/3GP files, use qtdemux as <demux>, for MKV, use matroskademux, for OGG use oggdemux
