MPV (license GPLv2, https://github.com/mpv-player) is the first video player with Vulkan support since 0.28. Wayland is supported by default since 0.29.
pacman -Sy mpv
To use Vulkan, you need to run MPV with or modify the start menu entry:
mpv --gpu-api=vulkan --player-operation-mode=pseudo-gui -- %U
At least on Plasma Wayland mpv 0.30 works fine with Vulkan in a Wayland window.
The AV1(BSD Clause 2, https://aomedia.googlesource.com) media codec has been officially released royalty-free by the Open Media Alliance (https://aomedia.org) on 2018-03-28 with broad support from all the major internet companies, read https://www.phoronix.com/scan.php?page=news_item&px=AV1-Released. On 2018-06-26 the version 1.0 has been released. AV1 claims to offer 30% better compression at 4K then the other media codec’s like VP9.
- DAV1D 0.1 (license BSD, https://code.videolan.org/videolan/dav1d) is a AV1 decoder from the VLC and ffmpeg communities. The decoding speed has been improved drastically in the last time.
- Firefox Nightly 59+ can decode and play AV1 already https://demo.bitmovin.com/public/firefox/av1. Firefox switched to dAV1d with Firefox 67.
- Experimental Vulkan branch with GPU offloading is available
- FFmpeg 4.2 supports AV1 via DAV1D. FFmpeg added in August 2019 the AMD advanced media framework (AMF) which is based on Vulkan initialization. With 4.3 Vulkan support should be in good shape.
