127 		- 0: this is an S-Video output
128 		- 1: this is an HDMI output

448 This output supports audio outputs as well: "Line-Out 1" and "Line-Out 2".
449 The S-Video output supports all TV standards.
451 This output supports all combinations of the field setting.
460 The HDMI output supports all CEA-861 and DMT timings, both progressive and

473 An HDMI output has a valid EDID which can be obtained through VIDIOC_G_EDID.
499 There are three types of VBI output devices: those that only support raw
503 The sliced VBI output supports the Wide Screen Signal and the teletext signal
506 The VBI device will only work for the S-Video output, it will give
507 back an error if the current output is HDMI.
592 The Metadata output can be used to set brightness, contrast, saturation and hue.
594 The Metadata device will only work for the Webcam output, it will give

1136 The vivid driver supports looping of video output to video input, VBI output
1137 to VBI input and RDS output to RDS input. For video/VBI looping this emulates
1138 as if a cable was hooked up between the output and input connector. So video
1157 until the video output has started. At that time the video output will be
1160 - the input type matches the output type. So the HDMI input cannot receive
1161   video from the S-Video output.
1163 - the video resolution of the video input must match that of the video output.
1164   So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz
1165   (720x480) S-Video input, or a 720p60 HDMI output to a 1080p30 input.

1344 Note: output overlays are primarily implemented in order to test the existing
1345 V4L2 output overlay API. Whether this API should be used for new drivers is
1348 This driver has support for an output overlay and is capable of:
1379 has that number of inputs. Each HDMI output will also create a
1382 this is the equivalent of hooking up each output device to an input port of
1383 the TV. Any remaining output devices remain unconnected.
1385 The EDID that each output reads reports a unique CEC physical address that is
1387 receiver has physical address A.B.0.0, then each output will see an EDID
1401 - Add support to loop raw VBI output to raw VBI input
1402 - Add support to loop teletext sliced VBI output to VBI input
1408 - Add support to loop from a specific output to a specific input across
