[QUESTION] Does ffmpeg use hardware acceleration on Linux about nwjs-ffmpeg-prebuilt

[iteufel]

@M4TH76
Try adding --ignore-gpu-blacklist to your chromium-args
Open chrome://gpu/ with nw.js and check if your GPU is blacklisted.
You can also try Installing the mesa and libva-intel-driver packages.

I've already added the arguments to chromium

Vainfo list h264 as supported

chrome://media-internals list video_decoder:ffmpeg... Instead of gpu..
That's why a asked if ffmpeg can use the gpu to decode video like it does on Windows

@M4TH76 Any chance you enabled hardware acceleration of h264 decode on MAC? If yes, whats the approach you used?

[M4TH76]

@Ajeey sorry not a Mac user...

Bump...
Can nwjs-ffmpeg-prebuilt use HW acceleration?

From what I understand, you actually need to apply a patch to chromium in order to enable H.264 hardware accelerated decoding. I played around with it a little bit a while back and managed to produce a version of nwjs with H.264 hardware decode enabled.

I put up a repo that has the patches for nwjs 15 (I uploaded a binary version of nwjs also): https://github.com/mocudev/nwjs_linux_hwdecode

There's also a branch where I started down the path of applying a newer patch to nwjs 25, however I had some issues getting it working and haven't had time to continue with it. This is where the patches are that I started going off of for the nwjs 25 branch: https://chromium-review.googlesource.com/c/chromium/src/+/532294

If the issue still exists just write it down and I will reopen the issue.
