Vivaldi not playing some gifv files
This is probably related to https://forum.vivaldi.net/topic/10686/video-and-gifvs-does-not-work-after-1-3-582-3-64-bit-update but I wanted to see if there's any update about this.
Here's an example of a file that doesn't work for me. I see a quick snapshot of the image and then the pag goes white:
I'd say it happens 90% of the time and it's bad enough that I don't even bother opening some links with vivaldi but have to copy and paste in firefox.
@llaen Your example works for me (and so do all the "problem" links on the old thread).
Vivaldi 1.8.770.25 (Official Build) dev (64-bit) on Mint 18.1 KDE.
As mentioned on the old thread, what does vivaldi://gpu show ( section "Graphics Feature Status" )?
I'm on 1.7.735.46.
Here's the output for Graphics Feature Status:

I'm not into GIFV format investigation. But, as far as I understand that's not real format like real GIF. Site like Imgur or Gfycat use a renamed HTML5 MP4 video without playing sound, then call it GIFV. A lot of people seem just mistakenly think they're a new format High Definition GIF.
That http://i.imgur.com/eYTBvRU.gifv doesn't play for me at first too. And my DevTools Console shouts that mp4 being "block". Only after I disable all my extensions the file just play. Currently, I don't have time to investigate which the culprit on my side.
Ugh, faster than I thought.
On my side it's "Disable HTML5 Autoplay" extension was the cause.
You need some chrome-codecs-ffmpeg package to play all videos.
Gwen-Dragon has already provided the solution but FYI, the file being played downloads as an mp4 and can be opened in VLC to show the codec (h264) needed.
@CantankRus You're right. It's h264 support that's missing.
Unfortunately installing chrome-codecs-ffmpeg on my system (opensuse; the package is chromium-ffmpegsumo) was a little more finicky. It required downgrading chromium to v54 and even then it didn't work.
ruario's latest-proprietary-media.sh script didn't seem to make a difference either.
I'll have to fiddle with this some more.
Thanks for all the great pointers!
Just another note... vivaldi-stable is using chrome v56 while vivaldi-snapshot is using chrome v57.
