The Raspberry PI 5 and 4B apparently support HEVC decoding in GPU using “v4l2 stateless API”
Apparently ffmpeg (at least version supplied with R Pi OS) has built in support.
since gstreamer-libav is a wrapper for ffmpeg that suggests it might be possible to to get this working through gstreamer, if it doesnt do it already.
Any thoughts or advice?
EDIT: information on the R Pi addition to ffmpeg (that uses stateless v4l2) can be found here: please identify where to find the stateless v4l2 code here? · Issue #94 · jc-kynesim/rpi-ffmpeg · GitHub
