As part of the ongoing enablement of AMD’s next generation RDNA 3 GPUs, the company has released a series of patches for Linux that reveal details about the company’s upcoming video engines, the Video Codec Next version 4.x. For now, VCN 4.x supports decoding of virtually all modern codecs, but for some reason AV1 encoding is not supported.
AMD’s VCN 4.0 engine appears to support H.264/MPEG 4 AVC, H.265, VP9, AV1, and JPEG decoding, but only H.264 and H.265 encoding. For now, VCN does not appear to support AV1 encoding as well as H.266/VVC (versatile video coding) decoding/encoding.
