@sgunhouse OS is win 7.opera version is 41.
@leocg ,it does not play,for example ,also can't playback twitter video.
I notice @avl ever said,on Windows platform,Opera need system natively decode support,does it mean HW decode accelerate？or mean software decode on OS? -

It means that Windows Media Player (or whatever media player that comes with Windows) should be able to play the file encoded in h264 without needing any codec pack to be installed.
OS is win 7
Win7 should be able to play h264 videos.
It's 32 or 64 bits? Your graphic cards supports hardware acceleration?
Try taking a look at opera://media-internals/ while playing a video (or trying to play), it may bring some info to you.

Hi,Legco.
My WMP can play MP4 which encoded in H264,but still opera can't.
Here is opera://media-internals/ info:"render_id: 172

My win7 is 64 bits and my graphic card is intel HD Graphics 4600 which does not support HW acceleration

And you never installed any codec?

Yes, it does support.
it display "initialization failed"
Does opera://gpu shows any error message? Do you see a GPU process in Opera's task manager?

I just installed FFmpeg/FFDshow codec to try if they could work H264 with Opera ,Do you mean I will unintall them ?

If there's a setting change that's causing the problem, going to opera://flags and resetting might fix things.

Opera can't use them as far as I know.
Do you mean I will unintall them ?
No, I mean that Opera can only play H264 (and some other codecs) if Windows can play them natively. In other words, Windows should be able to play those codecs just after having been installed.
Problems Detected
Did you check the whole page? Real problems are usually listed on the bottom of the page?
Also, are the items under 'Graphics Feature Status' with 'hardware accelerated' status? At least most of them.
