@freemangordon:

What about downloading TI DSP codecs and gst-dsp from apt repository instead N950 FW?

Here are links:

https://qa9recEP:Pat2UGuP@downloads....+0m6_armel.deb
https://qa9recEP:Pat2UGuP@downloads....+0m6_armel.deb
https://qa9recEP:Pat2UGuP@downloads....+0m6_armel.deb

Note: when downloading you need send Basic HTTP authentication information. Wget before 1.10.2 (which is on Nokia N900) do it automatically, new versions have option --auth-no-challenge

You can also download full index Packages.gz:

What about installing these deb packages directly on Nokia N900? You do not need backup libraries and when you want to revert, you can use apt-get...

PS: gstreamer0.10-dsp 0.9.0 has really LGPL copyright file!

EDIT:
Can you add info about camera-ui to first post (link for new version which support recording 720p)?
