2. once you get the pop up menu 
3. press and hold "power off" 
4. Boot on safe mode should become available

tried safe mode it works but i cant use facebook nor youtube on safe mode , and gets fixed on restart so it will not be obvious on safe mode except after houres of usage

The issue its caused by a third party app.

i made factory reset more than 10 times flashed many stock roms of defferent versions of lollipop , still the same after some while after restarting the phone the issue comes back , the only thing that fixed the issue was flashing cyanogen i hade no proplem in videos at all in cyanogen but i had another bugs concerning the cyanogen ,soi reverted back to stock i had the same issue again....
sry for bad english

its something wrong about videos it happens in camera app when trying to record , it happens in facebook that cant play any videos , youtube also , but if i opened facebook in chrome videos work correctly

@breka3

I want you to try something, repair the phone with PCC, yes even if you have done it before, do NOT add your Gmail address nor update any app, don't download any app then test the videos and report back
