#0921 problem with the CPU temperature , every time i watch a 1080p video (mp4,mkv,others), live TV etc. no matter what the extension / codec is, i have the icon that the CPU is overheating, i tested with mmal and OMX , both do the same thing
It didn't do that on every build before the #0921 (all previous firmware are fine)

What hardware is this RPi0, RPi1, RPi2, RPi3, RPi3+?

Can you post your config.txt.

Have you tried running bcmstat.sh Zyed1 and monitored the temperature and event flags during playback? What temps are you seeing?  

issue gone with the next build #0922
so no need to investigate further
NB : the temperature was very high (80° C / 176°F) with the icon bleeking that the PI3 was hot
