SOLVED: RKMPP setup correct but missing a step to have full transcode?

[azngunit81]

thanks @gnattu

so two things I tried

chmod -R 777 /dev/dma_heap/* && \
chmod -R 777 /dev/mpp_service && \
chmod -R 777 /dev/rga && \
chmod -R 777 /dev/mali0


this works but allowing 777 while root is a bit sketch

so , I returned them to 660 but as you have mentioned ive put them into the video group instead

chown -R root:video /dev/dma_heap && \
chown root:video /dev/mpp_service && \
chown root:video /dev/rga && \
chown root:video /dev/mali0


and that also worked!
as an extra check on the host promos console I've
watch -n 1 cat /sys/kernel/debug/rkrga/load

and saw the process transcoded.

the udev portion is not needed with this.

thanks for the help!
