When trying to build ffmpeg 8, the building process fails with these error messages:
libavdevice/v4l2.c: In function ‘device_open’:
libavdevice/v4l2.c:191:35: error: ‘V4L2_CAP_VIDEO_CAPTURE_MPLANE’ undeclared (first use in this function)
} else if (cap.capabilities & V4L2_CAP_VIDEO_CAPTURE_MPLANE) {

Other similar error messages related to planes or VIDEO_MAX_PLANES also appears.
FFmpeg 7.0.3 builds fine.
