Can't play Youtube videos.
-
I forgot to mention that I disabled all plugins. So there does not appear to be a conflict with a plugin.
-
@mmynsted Google sure is not making it easy to play YouTube videos with the Flash Player anymore...
YouTube is trying to play the video that you linked to using their HTML5 player but this H.264-encoded video cannot (currently) be played by Vivaldi on your Mac. This issue (and a temporary workaround for some Macs) has been discussed at length in the Mac Forums for a while now; look for the "Vivaldi can't play videos on [some] site" topics. All of us with blacklisted GPUs or older iMacs with Radeon GPUs are waiting for Vivaldi to finish implementing a fix.

Thank you. I read those and tried the black-list fix, and the hardware acceleration disable fix, but neither worked. I guess I just need to wait for a new version of Vivaldi.

@mmynsted At the moment, video formats (such as H.264) can currently only be played by Vivaldi on macOS when hardware acceleration is enabled and there is an active GPU Helper process. You can check this by opening vivaldi://gpu
If hardware acceleration is not available, some video formats simply will not play in Vivaldi on macOS.
This primarily occurs if the Chromium developers discover a graphics driver bug that affects their code and blacklist the driver. Some MacBook users also disable hardware acceleration intentionally with the hope that this will extend their battery life. Disabling hardware acceleration will partially break video playback.
Overriding the blacklist is not an ideal fix on some Macs because it can result in rendering glitches, degrade performance on some sites, or cause outright breakage. A fix truly is in the works that will enable proprietary media playback in these situations without having to resort to workarounds.
The other issue (affecting primarily older iMacs) is that a different decoding strategy is required for some Mac hardware. On those systems, some video formats will not play... with or without hardware acceleration. I hope that we're close to seeing a fix for this too.
I hope that this provides some additional clarity.

@detlevski After playing around with Vivaldi for a week now, I was very excited at first with all its features, especially with regards to bookmarks, tabs and session management. But with all the issues related to Videos not playing and the lack of Synchronisation... I'm forced to go back to Opera or Chrome. As a normal user, I am not concerned with the techno mumbo jumbo. First and foremost it must WORK ! Then the additional features come in play but if its not fully functional then its worthless to me. It's really a shame because had it not been for those 2 major functionality issues, Vivaldi would have become my first choice immediately
Its disconcerting that it does things so well that no other browser does... but then it can't do the basic things that ALL other browsers do ?!? -
I have found one "solution" , I think this problem are direct related with this new clean google like interface that youtube updated weeks ago.
Im selected to go back to old version of youtube and installed this userscript using tempermonkey = > YoubuteCenter
Now the broken videos are playing like a charm
I hope vivaldi fix this soon . Cya guys -
Hey guys, we are very much aware of this issue and are working on it. The underlying problem is that on Mac we use the Chromium hardware decoder to decode some h264 videos. When the GPU has been blacklisted by Chromium this decoder cannot be used. We are implementing a new mechanism where we hope to reuse our regular platform media decoding also in this case. This is a feature we haven't had before and it will take longer than a bug fix. We realize that this is a big inconvenience for Mac users with blacklisted GPUs and we will release it the moment we have it working and tested. Thanks for your patience!

Any news on this? Still having the issue 10.12.6 with 1.14.1077.55 (Stable channel) (64-bit).
Safari and Chromium (!!) are working well.
-
@vyedmic I asked the Vivaldi team about this over the weekend. The good news is that they haven't forgotten about us -- the work is still ongoing and they're making good progress. I don't know when the fix will be ready but I'm still happy that things are moving forward.
-
Are there any other tips for mac users to playback video in a reliable manner? I often have a video play only the first 20 seconds or so, then refuse to play in Vivaldi. Fire up Chrome, put in the same URL, and the entire video plays without issue.
-
Moving forward? Hey, it is now 2019 and i still have the same issue... so any idea when it will be fixed?
-
I too am waiting for a fix, been following this topic for a while and attempting any solutions I could find but none have seemed to work. Was about to make my own post as it seems all these topics are a year or so old; posting my specs here since I dug them up. Really would love to see Vivaldi work because I love using it but for the having to open Chrome to watch pretty much any video anywhere on the net.
Vivaldi Version: 2.3.1440.41
Mac OS: 10.10.5 (Mac Pro - Early 2009)
Graphics: NVIDIA GeForce GT 120 512 MBAttempted Solutions:
Updated Flash Player
Refreshed Profile (No change)
Installed Vivaldi Version 2.4 (Use preventing errors occurred, unrelated to video issues)
Hardware-accelerated video decode set to Enabled -
@rajjawa A fix for this issue just got released for testing in the 1455.4 Snapshot build:
[Mac][Media] AVC does not work with MSE on Mac if HWA is disabled (VB-40546)
We're now using a different method to decode H.264/AVC media streams that should work on all Macs, even when GPU hardware acceleration has been disabled. If testing continues to go well, hopefully the Vivaldi team can make this available to all Mac users in the next Vivaldi 2.3 Stable update.

@xyzzy I have just installed this version (I had also installed it previously) but the video errors continue to persist.
Vivaldi Version: 2.4.1455.4
Video Experiencing Issue: https://www.youtube.com/watch?v=dBuYczA1QjYAttempted Solutions:
Disabled and Reenabled Hardware Acceleration
Cleared Cache from All Time -
@rajjawa Welcome to the Vivaldi Community! Thanks very much for testing and thanks for the report; we're very sorry to hear that AVC video playback still is not working for you. Are you able to play this video with Safari?
-
@xyzzy Just tested that specific link and that video has no issues playing in:
Safari v0.1.2 (10603.3.8)
Chrome v76.0.3626.109
Firefox v65.0.1 -
@rajjawa Thanks again! I'll pass this info on to the Vivaldi team. This fix is still a work in progress and we really appreciate your feedback.
-
@rajjawa One other question: In vivaldi://flags were all flags at their default setting? You don't need to override the GPU blacklist anymore to get media playback working, and there's currently a bug where changing
#disable-accelerated-video-decode
will disable the new decoder, so that flag should be left at its default. -
@xyzzy I believe all flags were at default, however, I did hit the "Reset all to default" button and cleared the cache but the issue with that video and many others persist. I appreciate your escalation to the Vivaldi team, looking forward to the solution.
-
@xyzzy I also concur that this latest snapshot hasn't fixed playback for certain YouTube videos for me either, even after clearing cache + resetting flags
Mac OS = 10.13.6, iMac (27-inch, Mid 2010)
Graphics: ATI Radeon HD 5750 1024 MBThe affected videos that don't play in Vivaldi play just fine in Safari + Firefox
I did use an alternative front-end Invidious (basically replace "youtube.com" with "invidio.us" in the video URL) that so far seems to get around the problem in Vivaldi, which at least is better than nothing
