G/S_PARM doesn't make sense for the capture queue of a stateful encoder, unless V4L2_FMT_FLAG_ENC_CAP_FRAME_INTERVAL is set to reserve HW resources. See https://hverkuil.home.xs4all.nl/spec/userspace-api/v4l/vidioc-enum-fmt.html#fmtdesc-flags That flags isn't used, so v4l2-compliance shouldn't complain.
