For me it doesn't play. I tried to refresh de page 10 times. One time, it suddenly switched to Flash and was playing. I reload the page and it didn't play anything again.

Really annoying since I would say about 70% of the cases, that errors happens when going on the video pay. When reloading, half of them suddenly plays, and the rest simply fails.

Same. Some videos works, some cannot be read (error while loading the video)

I was ready to give up Chrome for Opera or Safari.
But safari a trouble with Adblock and very huge memory link screwing the computer.

but Opera has problem with h264 video.

Google are ***** who want to push VP9, when its it not possible to have smooth video in 1080p without burning the computer or having a very powerful computer (core i5 @ 2.53 ghz, dualcore is not enough...) because this shitty codec is not supported for hardware acceleration.

My conclusion is the following. There is a stupid war open source vs the proprietary. Some companies/ only accept open source, even if the open source equivalent does not exists or is big crap. Apparently, it in some people's mind, it is not possible to use and support open source by using proprietary stuff at the same time, at least by the time the open source equivalent is good enough. Who are the victims? US, USERS are VICTIMS in this stupid war.
What if I told you I can support H.264 now because the VP9 need to much power for HD video and support VP9 when it will be supported by GPU, and use it only for non HD video for now?
