What do we lose if we root/delete the stagefright libraries?
On my Nexus 7 tilapia / Cyanogenmod, 2015-07-26 snapshot I believe, I tried
mount -o remount,rw
mv libstagefright* sf.bak
Tried a couple of apps, seemed OK, so re-booted.
Hung on the boot spinner, didn't get as far as prompting to decrypt the user partition
