From what I found on the web, people seem to be having issues with hardware acceleration on the pi 4 running Buster (CPU does the decoding instead of GPU). Is hardware acceleration not supported? If it's not, why? Will it be supported in the next release of Raspbian? And what about the H.265 hardware decoder, is that supported or will it ever be?

  • what makes you believe the GPU is not doing its job? Dec 4, 2019 at 3:33
  • I've seen issues with older versions of Rasbian that caused the hardware acceleration not to work at all (if the corresponding option in the config was enabled, the minecraft demo would not start), but after a recent driver update, everything seems to be fine.

  • I saw some YouTube videos and forum posts. I guess the Raspbian developers disabled hardware acceleration after finding a bug, but it looks like it's been enabled in the latest release

  • But I believe the H.265 hardware decoder is still not working

The foundation has their own (downstream) version of ffmpeg with HEVC decode (!) acceleration:


HEVC acceleration in VLC is currently being beta tested : https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=257395

I suppose patches for Chromium will come after that ...
