html5 - Google Chrome 28 doesn't play mp4 videos -

-

i have issue @ moment cannot .mp4 videos play on google chrome 28, happens on windows 7 machines, not of them.

as stands, able replicate issue on 3 windows machines out of five.

even if enter direct url .mp4 file in address bar, chrome still won't play it.

can here replicate issue? have used few different .mp4 files test, here's one: http://www.w3.org/2010/05/video/mediaevents.html

i appreciate help.

note: going chrome advances settings , turning off "use hardware acceleration when available" chrome able play video, option turned on default, not perfect solution problem.

thanks lot.

update: updating video drivers fixed it, again... not ideal solution...

we had problem... both webm , theora/ogg worked fine in chrome , mp4 video worked fine on ie9 , in firefox. chrome fails.

we manage fix updating video drivers (intel hd on dell pc), looks problem in h.264 acceleration used in chrome , old intel drivers
