Mythtv on Raspberry Pi

[williamdosa]

So i have been running mythtv on a raspberry pi ever since it was available for it. however when they moved the pi kernel from 4.9 -> 4.14 my performance was horrendous. videos did not play well AT ALL. i forcibly rolled back to a 4.9 kernel and everything just starts working again. I have tried moving it to 4.14 a couple times since and it has not seemed to get any better. I am using the mythtv Lite builds but i cannot figure out what is causing the performance difference. has anybody else had this issue, and if so solved it?

I moved the post to the Raspberry Pi board.

Recent versions of Raspbian have caused some bad performance problems. I found that you need to switch to "OpenMax Normal" Video profile and make sure you do not have -v playback in your mythfrontend command. There are more tips on improving performance in the wiki page at

Let me know whether this solves your problem.
