Vivaldi won't reproduce some YouTube videos
-
@andorea Thanks very much for reporting this!
Please ensure that the "Use hardware acceleration when available" option is enabled. Currently, Vivaldi is not able to play certain types of media on macOS if hardware acceleration is disabled.
One other thing: Are you using an extension (such as "h264ify") that prioritizes H.264 (MPEG-4 AVC) over other codecs? If so, try disabling that. The YouTube video in your original post should play with the VP9 codec by default, and should play fine on your iMac with or without hardware acceleration.

I was having this problem on a MacPro 1,1 with an upgraded Radeon 5770 under 10.9.5. Overriding the GPU blacklist solved this for me.
edit: played two videos then happened again. Blacklist is still disabled. Not even disabling HW accel solves it.

@tigas Thanks very much for posting this information.
Videos can be encoded and packaged in many different ways. Some types of video play fine on macOS with or without hardware acceleration; some require it.
The problem the devs are working to resolve at the moment are with Macs that currently won't play some media types, with or without hardware acceleration enabled in Vivaldi. The ideal fix has to decode video in the most efficient way possible, work with or without a blacklisted GPU, and take into account that the hardware decoding capabilities across Mac models are different.

I'm having this problem with twitter videos since forever, now.
It's the only reason V is not my main browser. Is there a surefire, maybe hacky, workaround for it while the devs don't fix it? Maybe extract the codecs from a chrome instalation or compiling a mac version from some linux repos or something?

@bohemiadrinker Unfortunately, it doesn't work that way on macOS. If
vivaldi://gpu
says that hardware acceleration is enabled but some types of media still won't play on your system, there really aren't any other viable workarounds.The fastest way (REALLY!) of getting focus on this issue and getting it fixed is to:
- File a bug report at https://vivaldi.com/bugreport/ -- be sure to include a URL to a video that won't play on your system.
- Go the the
vivaldi://gpu
page and save a copy using Tools / Capture / Page to File. - When you get a confirmation email from the bug tracker, reply to it, attach the
vivaldi://gpu
stats, and send the file to Vivaldi.
Posting to the Forums isn't enough; If lots and lots of people actually file bugs, including those that need to override the blacklist to get video playback working, the necessary resources will get dedicated to fixing this.

@xyzzy Thanks for the answer
The hardware acceleration option is enabled and I don't have any extension that prioritizes H.264.
I don't think this is a hardware problem, I can open any video with all other browsers, This seem to be a Vivaldi only bug on macOS...
Please try to fix it, I don't want to go back to Firefox, it's too memory expensive...
-
@andorea Thanks very much for the update. Hopefully we'll see some improvements to the media playback situation on macOS soon.

Oh, I have filed the bug some times now ( every two or three snapshots). No dice so far, that's why I was looking into macgvering something.

@bohemiadrinker Are you still using Snapshots or are you currently using the Stable release? There haven't been any announcements in the changelog but a few little fixes have actually already been implemented.
Snapshot users with blacklisted GPUs (and no hardware acceleration) should be able to play the videos on this test site: https://www.quirksmode.org/html5/tests/video.html
That said, some video playback still requires hardware acceleration to be enabled (or forced on by overriding the GPU blacklist in
vivaldi://flags
)Some media playback issues are also very hardware specific and only affect a few Mac models; that's why the developers need to know what sites are still broken and which specific Mac models and macOS versions are affected.

I'm always on the latest snapshot, and I can play the videos on the site. What doesn't work for me is Twitter and (I just discovered this) Gamespot. Youtube, Vimeo and the likes are fine.
