H.264/mp4 video not working

knoelli

For some reason, I can't play any html5 h.264/mp4 videos in Vivaldi, html5 video encoded as WebM or Ogg play just fine. This problem exists since some time and all things I tried so far didn't work out. This is for example a problem on www.imdb.com where I can't see any trailers (I get a red error message reading: "Sorry, this video is unsupported on this browser"). The test page at [url=http://www.quirksmode.org/html5/tests/video.html]http://www.quirksmode.org/html5/tests/video.html[/url] doesn't render the h.264 video, I only see (inactive) player controls. Some details: [ul] [li]- I'm running Windows 10 (x64)[/li] [li]- Graphics card is an (old) Intel 945 Express[/li] [li]- the problem is present in Vivaldi 1.1.453.45 (x86), Vivaldi 1.0.380.2 (x86, standalone), Vivaldi 1.1.453.47 (x64, standalone)[/li] [li]- Chrome 50.0.2661.87 plays h.264 videos just fine (and so does MS Edge)[/li] [li]- booting into Ubuntu 15.10 and running Vivaldi for Linux, the h.264 videos play without problems[/li] [li]- I tried with a clean profile & without any extensions but to no avail[/li] [li]- installing the latest K-lite codec pack didn't change anything[/li] [li]- I tried disabling the video hardware-acceleration in flags and also tried with --disable-gpu-sandbox option[/li] [/ul] I thought it might be a driver problem (due to the very dated hardware), or maybe a codec problem, but since Chrome 50 does render those videos without problems, I'm really out of ideas what's wrong here.

No external codec needed on windows to get vivaldi working, although the LAV filters, usually, won't mess anything unless specifically instructed.

Pleas check if the MS codecs are set as default and registered correctly with one of the many codec setup tools.

Also uninstalling the Klite package, usually resets the windows settings to the stock status

Thanks a lot for your suggestions. I tried with the CodecTweakTool to fix potential problems (General->Fixes) and also had a look at the DirectShow codecs, they are all installed and activated. I also tried to set the preferred splitters to the ones recommended by the tool (in most cases LAV). Windows Media Player correctly plays any h264 or mp4 video, so I think the codecs should be set up correctly. Additionally I ran a scan with the quite old tool "Filmerit" which reported no problems with the installed codecs. Also trying to uninstall (+reboot) K-Lite didn't change the problems.

The page chrome://gpu in fact shows quite a number of problems - like I wrote, my graphics chip is quite dated… See the spoiler for the reported problems:

So yes, there are in fact problems with my graphics card, however since everything else (Chrome, Edge, Vivaldi @Linux, WMP) render those videos without problems, it's really quite strange why Vivaldi (on Windows) and only Vivaldi has this problem. :unsure:

Out of curiosity try the current Opera .

As a rule of thumb. If Opera Plays the videos it's a Vivaldi problem, If opera shows the same problem, your problem is in windows/drivers/codecs/ or maybe unsupported HW, as you told.

Anyway I'm using a no so recent Intel GMA4500 That while newer than yours isn't surely the latest novelty, and Vivaldi://gpu as a fairly long list of compatibility issues and disabled features.

Thanks a lot to both of you for your ideas.

Well, the current Opera developer doesn't play h264/mp4 videos as well. So it really seems to be an issue with my (old) graphics device not supporting hardware acceleration for the codecs used by Vivaldi/Opera. It's really a pity and with more and more sites switching to html5 video instead of flash (which in general is a good development imho) it would be great to have a solution for this problem…

Hope I'm not hijacking anything, but can I ask what Vivaldi should or shouldn't play vs other browsers, specifically Chrome ?

Have been experimenting a bit with media player Emby in Vivaldi and it doesn't play an awful lot of media - doesn't like MKV files as far as I can tell. Would that be my PC or can't Vivaldi do that (yet) ? Can play this stuff fine in Chrome.

Thanks very much.
