iohann.s.titov@gmail.com Ivan S. Titov rocDecode decodes video on the dedicated VCN block of AMD GPUs through VA-API, covering H.264, HEVC, AV1 and VP9. Decoded frames stay in device memory, so a decode-then-infer pipeline never copies them back through the host. It is the video counterpart to media-libs/rocJPEG and ships a bitstream parser and demuxer helpers alongside the decoder itself. Build the additional host-side software decoder, which falls back to media-video/ffmpeg for streams the hardware block cannot handle ROCm/rocm-systems
