RPI4 Chromium and video acceleration

[MatheCheck]

I got my Raspberry Pi 4 model B 8GB on monday and installed Arch Linux Arm aarch64. I followed the installation guide with the minor tweak of running rpi-update on the SD card, otherwise the pi would return mmc1 -110 error on boot. Now it works like a charm, 3D acceleration and Vulkan included but I'm really struggling to enable hardware video decode on Chromium: no matter what combination of configuration options and flags + enahancedH264ify I use on chromium, it always uses software decoding (FfmpegVideoDecoder, VpxVideoDecoder). I thought it just wasn't supported for aarch64 but last news is older than a year. Am I missing something?

Not sure about chromium but vlc and kodi on RPi4 use hw acceleration for video but a requirement is the linux-rpi kernel (RPi Foundation fork) not vanilla kernel.

You are a hero. There's something odd with my installation of chromium but after following [url=https://archlinuxarm.org/forum/viewtopic.php?f=65&t=15128]Fresh Raspberry Pi 4B Install with linux-raspberrypi4 Kernel[/url] (linux-raspberrypi4 has become linux-rpi) my chromium settings pactically removed the huge amount of lag lag when cloud gaming, left no cpu usage spiking up and youtube 1080p is really smooth. Thanks!

Glad you're happy with the distro. Enjoy.
