TED Talks not playing again
Disclosure: I work for TED.
In the past, TED Talks did not play on Vivaldi, but that problem was resolved. Problems seems to have resurfaced. Try any talk, e.g., https://www.ted.com/talks/ray_dalio_how_to_build_a_company_where_the_best_ideas_win
It's probably Mac specific, the link you provided works in Vivaldi 1.12.947.3 -
Windows 7 32bit
@mmcwatters On macOS, Vivaldi uses the graphics card (GPU) on your system to decode certain types of video. However, it's likely that the GPU on your system was blacklisted by the Chromium developers.
You can check the hardware acceleration status by going to: vivaldi://gpu
If hardware acceleration is unavailable, please try the following:
Go to vivaldi://flags and Enable the "Override software rendering list" flag; it's the first entry on the page. Then hit the Relaunch button at the bottom of the page. This should enable the TED Talk (and other) videos to play again on your system.
The Vivaldi developers are working on a fix for this and other media-related issues on macOS.
