It seems to be impossible, CE kernel version is 2.6.37 , and seems that DSP driver is broken, or at least I am unable to load baseimage.dof succesfully:

Code:

[ 1884.846252] omap-dsp omap-dsp: ERR: clock id 2 already disabled
[ 1884.852691] DSP could not be restarted

And having in mind there is HW adaptation team working on that kernel (something Maemo kernel lacks), I would prefer them to fix it, not me. I will stay focused on kernel-power instead.

What is also broken in CE kernel is omap3isp(camera HW resizer), which renders gstreamer camera element useless.

Code:

Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2NewCamSrc:v4l2newcamsrc0: Device '/dev/video0' is not a capture device.

So for now no hope for Meego CE to play/record 720p videos

Once downloaded the file is not re-downloaded again. The file should be put in /home/user/MyDocs/RX71.tmp

I wonder if we can be awaiting some miracles happening after the new firmware for n9 with the new dsp is released?

Okay, just ran the script on my N900 to install the patch:

I can now play 720p H264 base profile video without any issues after a fresh reboot and running at default clock for CPU and DSP. (using KP49) I didn't need to overclock the DSP at all. Hmm. Maybe my video isn't demanding enough to need it? Anyways, very happy that it's working. But yeah, it's not the most useful capability when I still need to re-encode to such encoding settings. But still feels good that the N900 can now play videos nearly as good as my N9. (which is sad in a way as I wish N9 was much better)

Gonna try a 720p xvid + AC3 AVI video later on. Hope it works.
(Just tried it and it works perfect. So this is a huge improvement!)

Anyways, awesome work freemangordon!

p.s. btw, there are times when it always says Media format not supported no matter what I do. Once I reboot, it works fine. Then, later, it happens again and I have to reboot. Any idea why this might happen?

@jakiman - bridgedriver in KP49 is still not stable, that is why. Anyway I was able to succesfully backport the one from Harmattan, works like charm and is much faster, but will need more time for testing.

@Jakiman

For the "Unable to Play Media" error, try this:

sh /usr/libexec/dsp-recover

I know that this can occur if too low voltage are set for CPU.
