chromium and video hardware acceleration

Well, sorry, I am going to rewrite.
The question is, how can I get the video acceleration hardware enabled in chromium/chrome, I tested it in windows and it's function without any type of special configuration, my gpu supports it; but in linux when I white list the gpu it continues without doing it, I have an amd card with privative drivers and a limitation cpu and for this I am asking how to do it, I know that at the moment in linux is buggy but I heard that the drivers and all the open stack are better each month, don't should chrome come with it predeterminated now? Can I put the video acceleration enable? Thanks
Sorry for my before English, was a mix of being tired and ignorance in English I amd trying to increase my level but it is complicated while you are studying
PD: I test the hardware video acceleration in chromium or chrome with pepper flash in a video flash of YouTube, and yes, I have in chrome://flags the option of ignore list of gpu...

Re: chromium and video hardware acceleration

Take a breath. Your post is very difficult to understand. If English is not your mother tongue, consider posting in the Other Languages board, or edit your post and include the actual issue and your question...

Re: chromium and video hardware acceleration

Just keep in mind that Google uses a GPU blacklist for a reason. Disabling it may cause full system crashes.

Re: chromium and video hardware acceleration

this thing, the ignore of rendering software list, it is something that i did, yes, if I go to chrome://gpu the output tell me that there are hardware acceleration, but when i put a video, in that page appear aone log, this log tell me that there isn't acceleration for profile one, in windows I have acceleration, why not in linux if it's possible, I only want to experiment how is it of buggy because with each year I noticed the better drivers and less bugs, I think the drivers are prepared now for acceleration because chrome os have acceleration.. and it's a linux distribution...

Full system crashes? If you're talking about userspace crash, it's acceptable, but it requires to be fixed. By system crash I understand kernel crash which is totally unacceptable.

Can you post the output of that log?  and how did you determine that hardware acceleration isn't working?
Also, I'm still not sure whether you are using xf86-video-ati or catalyst drivers.

afaik, VA-API/VDPAU accelerated video decoding still doesn't work with chrome/chromium or pepper, but the video output itself should get hw accelerated at least after disabling gpu blacklist.

Some time back I kept wondering why computer kept crashing until I found out I undid the GPU blacklist (not that chromium needs these tweaks to bring down everything)

Re: chromium and video hardware acceleration

I can't put any log now but I can tell that I tested the hardware acceleration with the stats for nerds of youtube with pepper flash, and I have catalyst video drivers installed. In the stats for nerds the output is that the rendering is accelerated but the video is software accelerated, there isn't a way to enable this?

afaik, accelerated video decoding isn't currently possible on linux with pepper flash plugin (unless there's been some progress in this recently, but I couldn't find anything with quick glance on google).

I believe hardware accelerated decoding should be possible with legacy flashplugin, but I can't remember the details and the plugin won't work with chrome/chromium any more, because they removed the old netscape plugin interface. Google for 'VDPAU flash linux' or similar if you're interested, and how to enable VDPAU/VA-API on your system from wiki (if you haven't already).

Apparently HW decoding should work with html5 video, but I suppose it is still more cpu heavy than plugins or standalone video player because of how the browser's renderer works.

Re: chromium and video hardware acceleration

Yes, I use pepper flash and thanks for the help, other question how can I see if chromium uses hardware acceleration for videos like html5 youtube? And other question that is a little bit different, in vlc there is video acceleration I think, this is automatic or I need to do something? I have amd catalyst installed

Re: chromium and video hardware acceleration

You need to patch Chromium for hardware decoding of HTML5 video. Though last time I tried it, it didn't work, loading VAAPI failed for some reason.

For VLC, hardware decoding is automatic with VDPAU, but Catalyst uses VAAPI. You need to configure that yourself, so go to "Input / Codecs" in settings and set "Hardware-accelerated decoding" to "VA-API video decoder".

On my intel system, in chrome://gpu I can see "Video Decode: Hardware accelerated" so I thought it should be working. But after reading Gusar's comment I'm not so sure any more..

For hw decoding on VLC (and everywhere else) with catalyst, looks like you have to install a few packages from AUR also: https://wiki.archlinux.org/index.php/VA-API

Re: chromium and video hardware acceleration

No packages from AUR needed for VLC anymore, the latest Catalyst versions (14.12 and newer) have an internal VAAPI wrapper.
