This is the jellyfish h264 demo on a #librem5 using the #imx8mq's #hantro VPU.

Using the CPU we take 300% of CPU time, using the VPU instead we take 10% (and even that can be optimized further). Using the VPU also saves ~1.5W of power. Thanks go to the #gstreamer and #linux kernel folks for making this possible!

@agx, I hope that this means that we will soon have H.265 decoding soon as well:

@amosbatto at some point yes, but afaik #gstreamer devs are still working on support for that (but they merged Ezequiel Garcia #h264 changes today so it will be part of future gstreamer releases, yay!)
