Well, stopping tracker was a quick workaround for its stupidity (trying to index files while camera is recording) until i figure out the correct dbus commands for pause and continue... exactly what you've done. And playing with priorities and other stuff is one of the reason why I made a script instead of hard-coding it in camera-ui. next step will be to move camera-ui in another cgroup while recording,pulling it out from standby tasks cgroup where Nokians in their etheral wisdom had put. Thanks, will test that, but my expectations are that it will work like charm. BTW some cheating for time to time won't hurt .
