OK, I finally did it (big thanks to Nokia and TI for DSP codecs of course) DO IT ON YOUR OWN RISK. I WILL NOT ACCEPT ANY CLAIMS FOR DATA/FUNCTIONALITY LOSS CAUSED BY FOLLOWING THE STEPS BELOW In order to watch 720p videos on your n900 you will need: - wget and kernel-power v49 installed on your n900 - your n900 connected to internet 1. Download attached .deb files on your n900 in a directory of your choice 2. from xterm as root cd to that directory and install .deb files dpkg -i omap3-dsp-baseimage-ti_0.i3.6-15+0m6_armel.deb omap3-dsp-libraries-ti_0.i3.6-15+0m6_armel.deb omap3-dsp-hd-codecs_0.3.8-7+0m6_armel.deb 3. from attached libgstdsp.zip copy libgstdsp.so to your n900 /usr/lib/gstreamer-0.10/libgstdsp.so 4. uninstall gstreamer0.10-openmax from n900. As root: apt-get remove gstreamer0.10-openmax 5. Reboot you n900 and enjoy In order HD playback to be smooth you will need DSP overclock. There is kernel-power profile called "dsp" that could be used Search appropriate threads for how to overclock DSP. Not all 720p videos will be playable of course, n900 DSP is just not powerful enough for some profiles. To remove 720p playback look here For video recording in DVD/HD you should install latest CSSU-T libgstdsp.so source code https://meego.gitorious.org/~freeman...rees/maemo5-hd Changelog 28.09.2011 Instructions updated. Camera is working now. Much more videos will be playable in media player (and OMP hopefully),because of the new mafw-gst-renderer. Changelog 01.10.2011 mafw-gst-...-renderer removed Changelog 02.10.2011 kernel-power v49 is needed bridgedriver.ko version for kp49 included in 720p.zip Changelog 01.11.2011 modified bridgedriver.ko no longer needed as the one in kernel-power supports both new and old ioctl codes. Changelog 21.11.2011 No more scripts needed. Added link to camera-ui for HD/DVD video recording. Changelog 09.12.2011 libgstdsp.so build against FREMANTLE SDK. Videocall functionality restored. Changelog 15.12.2011 New libgstdsp.so - fixes broken playback for some videos. Changelog 17.12.2011 New libgstdsp.so - fixes broken(by previous update) videocall.
