The VPU (video processing unit) in the Jupiter’s SpaceMIT K1(1.6GHz)/M1(1.8GHz) SoC supports H.265/H.264/VP8/VP9/MPEG4/MPEG2 video decoding 4K@60fps, but it does not support AV1.
Recently (2024-03) support in dav1d was improved for RISC-V (riscv64 standards compliant RVV 1.0+).
Can this board, and it’s Octa-core X60 with RVV 1.0, playback AV1 video using software decoding only ? And if so, can it do it at 1920x1080@30Hz ? The maximum resolution supported by HDMI on the Jupiter is 1920x1440@60Hz, so how about 1920x1080@60Hz ?
EDIT: I better include a few links to some sample videos in AV1 format.
From Netflix’s opencontent (9 minute 11 second duration):

Some small 10 second duration AV1 in WebM format can be downloaded from:
