One additional topic: The V4L2 API has a number of experimental API elements, see: http://hverkuil.home.xs4all.nl/spec/media.html#experimental The following have been in use for a considerable amount of time I and propose to drop the experimental tag: Video Output Overlay (OSD) Interface, the section called “Video Output Overlay Interface”. V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY, enum v4l2_buf_type, Table 3.3, “enum v4l2_buf_type”. V4L2_CAP_VIDEO_OUTPUT_OVERLAY, VIDIOC_QUERYCAP ioctl, Table A.92, “Device Capabilities Flags”. VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS ioctls. VIDIOC_G_ENC_INDEX ioctl. VIDIOC_ENCODER_CMD and VIDIOC_TRY_ENCODER_CMD ioctls. VIDIOC_DECODER_CMD and VIDIOC_TRY_DECODER_CMD ioctls. While the (TRY_)DECODER_CMD ioctls are strictly speaking new to V4L2 (appearing in 3.4) they started life as identical ioctls (although with a different name) in dvb/video.h. Other than being renamed and folded into the V4L2 specification they are quite old as well.
