This problem has not been solved for a long time. When I need to watch videos I just switch to firefox.
Many solutions have been given on google chrome forum such as “upgrade your system”, “upgrade your chrome”, “disable flash plugin in chrome”. However none of them worked on fedora 24.
As my case is neither lead by system nor chrome itself. I am using the stable version both for fedora and chrome. (I have not been adventurous when I started pursuing PhD degree) I guess some internal settings would affect the video playing.
* cache and history
* hardware acceleration
* flash inside google chrome: /opt/google/chrome/PepperFlash/libpepflashplayer.so
For my case shut down “hardware acceleration” save youtube.
