6 This driver emulates video4linux hardware of various types: video capture, video
7 output, vbi capture and output, metadata capture and output, radio receivers and
8 transmitters, touch capture and a software defined radio receiver. In addition a
9 simple framebuffer device is available for testing capture and output overlays.
13 Each input can be a webcam, TV capture device, S-Video capture device or an HDMI
14 capture device. Each output can be an S-Video output device or an HDMI output
35 - Raw and Sliced VBI capture and output support
38 - Capture and output overlay support
39 - Metadata capture and output support
40 - Touch capture support
47 By default the driver will create a single instance that has a video capture
49 S-Video and HDMI outputs, one vbi capture device, one vbi output device, one
66 - bit 0: Video Capture node
67 - bit 2-3: VBI Capture node: 0 = none, 1 = raw vbi, 2 = sliced vbi, 3 = both
74 - bit 17: Metadata Capture node
76 - bit 19: Touch Capture node
78 So to create four instances, the first two with just one video capture
89 are created for each video capture device. At most 16 inputs can be created,

442 Like with video capture the framerate is also exact in the long term.

482 There are three types of VBI capture devices: those that only support raw

582 The Metadata capture generates UVC format metadata. The PTS and SCR are

1273 Capture Overlay
1276 Note: capture overlay support is implemented primarily to test the existing
1277 V4L2 capture overlay API. In practice few if any GPUs support such overlays
1284 This driver has support for a destructive capture overlay with bitmap clipping
