As an addendum to this, I found out Chrome doesn't even have GPU acceleration enabled by default.

Type chrome://gpu in the address bar. If you've got of unavailable options there. Chances are it's off.

Type chrome://flags in the address bar. Click Enable on the first option under Experiments "Override software rendering list"

Saved me quite a few CPU cycles, voila.

It's enabled for most people. There might be a good reason why your GPU (or GPU drivers) are blacklisted; see https://chromium.googlesource.com/chromium/deps/gpu/software...

Weird. Not anything I can see immediately. However this is an ATI 6970 I EFI flashed to work on a 2008 MacPro.

Really? The fact that you hacked a GPU to work on your Mac didn't immediately raise red flags?

There's absolutely no reason to suspect that a web browser cares what kind of firmware you used to boot your OS.

No, because it's a supported GPU in Mac ATI drivers.

I'm on mac and it lists a bunch of mac specific issues for why certain hardware acceleration is disabled (multi-monitors, etc)

I've been using h264ify in Chrome on OSX for some time, but lately it started having problems with seeking/rewinding. Have to switch to Safari when I want to rewind. Managed to cobble together a chrome extension that opens the current url in Safari, also pausing the video and using the current playback time (too rough to share).

If you have mpv and youtube-dl, you can just `mpv http://youtube.com/whatever` and it'll play. Much better performance than anything in browser from my experience.

I just have a keybinding for `mpv $(xsel -o)` which plays whatever url I have in my clipboard in mpv.
