    Found a solution that worked for me. I have a late 2012 rMBP running airplay on an ATV3. After upgrading to El Capitan airplay video became laggy and my fans would run hard.  I open activity monitor to see that two processes were taking up 200% of CPU.   The main culprit was XPEncoder (app 150%) and Airplay XPC helper (app 50%). If I close both of these processes one right after the other, airplay turns off. If I then restart it, everything is fixed. When you restart your computer the problem returns and you have to repeat the procedure, so it isn't a longterm fix, but at least I can watch videos on my projector again until apple sorts this out.


    Hope this helps some people.
