google chrome - How to allow system sleep on non-fullscreen html5 video? -

we created little chat client in our office runs in browser. handles people posting pictures , gifs , embeds them. added back upwards imgur , gfycat's html 5 video (it auto converts gifs mp4/webm). unintented side effect of using chrome or firefox find monitor never turn off.

you can see in powercfg culprit these videos:

c:\windows\system32>powercfg /requests display: [process] \device\harddiskvolume2\program files (x86)\google\chrome\application\chrome.exe playing video [process] \device\harddiskvolume2\program files (x86)\mozilla firefox\firefox.exe

if pause videos, entries in powercfg disappear. switching tab, minimizing chrome, locking screen don't allow scheme turn monitor off. net explorer seems browser behaves you'd expect , prevents sleep when video fullscreen.

is there way mark video tag 'unimportant' , tell browser it's ok allow computer sleep while video playing?

it seems there bug in google chrome 38 (current release of writing) causes screen saver suppressed when playing html5 video. normally, screensaver suppression should occur when video playing in full-screen mode.

this issue appears resolved in beta release of google chrome version 39 looks temporary prepare made.
