3 The Virtual Video Test Driver (vivid)
6 This driver emulates video4linux hardware of various types: video capture, video
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
29 - Support for various pixel aspect ratios and video aspect ratios
47 By default the driver will create a single instance that has a video capture
48 device with webcam, TV, S-Video and HDMI inputs, a video output device with
49 S-Video and HDMI outputs, one vbi capture device, one vbi output device, one
52 The number of instances, devices, video inputs and outputs and their types are
66 - bit 0: Video Capture node
70 - bit 8: Video Output node
78 So to create four instances, the first two with just one video capture
79 device, the second two with just one video output device you would pass
89 are created for each video capture device. At most 16 inputs can be created,
102 - 10: this is an S-Video input
105 So to create a video capture device with 8 inputs where input 0 is a TV
106 tuner, inputs 1-3 are S-Video inputs and inputs 4-7 are HDMI inputs you
116 are created for each video output device. At most 16 outputs can be
127 - 0: this is an S-Video output
130 So to create a video output device with 8 outputs where outputs 0-3 are
131 S-Video outputs and outputs 4-7 are HDMI outputs you would use the
140 give the desired videoX start number for each video capture device.
142 you to map capture video nodes to specific videoX device nodes. Example:
148 This will attempt to assign /dev/video2 for the video capture device of
155 give the desired videoX start number for each video output device.
200 specify the allowed video capture crop/compose/scaling combination
201 for each driver instance. Video capture devices can have any combination
232 specify the allowed video output crop/compose/scaling combination
233 for each driver instance. Video output devices can have any combination
320 Video Capture
323 This is probably the most frequently used feature. The video capture device
326 but by default four inputs are configured: a webcam, a TV tuner, an S-Video
352 TV and S-Video Inputs
355 The only difference between the TV and S-Video input is that the TV has a
378 The initially selected colorspace when you switch to the TV or S-Video input
381 The pixel aspect ratio will depend on the TV standard. The video aspect ratio
383 Choices are '4x3', '16x9' which will give letterboxed widescreen video and
385 video that will need to be scaled accordingly.
426 The video aspect ratio can be selected through the 'DV Timings Aspect Ratio'
429 result in pillarboxed or letterboxed video.
442 Video Output
445 The video output device can be configured by using the module options
448 an S-Video and an HDMI input, one output for each output type. Those are
451 Like with video capture the framerate is also exact in the long term.
454 S-Video Output
458 The S-Video output supports all TV standards.
462 The initially selected colorspace when you switch to the TV or S-Video input
498 it will generate the Wide Screen Signal which is based on the actual Video
501 The VBI device will only work for the S-Video and TV inputs, it will give

634 User Controls - Video Capture
637 The following controls are specific to video capture.
641 video input has its own brightness value, so changing input will restore
642 the brightness for that input. In addition, each video input uses a different

718 adds a SAV (Start of Active Video) code to the image.
724 does the same for the EAV (End of Active Video) code.
726 - Insert Video Guard Band
728 adds 4 columns of pixels with the HDMI Video Guard Band code at the
731 to the HDMI Video Guard Band code that precedes each active video line
732 (see section 5.2.2.1 in the HDMI 1.3 Specification). To test if a video
733 receiver has correct HDMI Video Guard Band processing, enable this
735 That will result in video lines that start with multiple pixels that
736 have the same value as the Video Guard Band that precedes them.
737 Receivers that will just keep skipping Video Guard Band values will
738 now fail and either loose sync or these video lines will shift.
744 These controls are all specific to video capture.
761 S-Video input should be 4x3, 16x9 or anamorphic widescreen. This may
818 be limited or full range. This combines with the Digital Video 'Rx RGB

1138 Video, Sliced VBI and HDMI CEC Looping
1141 Video Looping functionality is supported for devices created by the same
1143 The vivid driver supports looping of video and Sliced VBI data between an S-Video output
1144 and an S-Video input. It also supports looping of video and HDMI CEC data between an
1147 To enable looping, set the 'HDMI/S-Video XXX-N Is Connected To' control(s) to select
1152 XXX will be 000. And N is the Nth S-Video/HDMI input or output of that instance.
1153 If vivid is loaded without module options, then you can connect the S-Video 000-0 input
1154 to the S-Video 000-0 output, or the HDMI 000-0 input to the HDMI 000-0 output.
1158 If an 'HDMI/S-Video XXX-N Is Connected To' control selected an output, then the video
1159 output will be looped to the video input provided that:
1166 - the video resolution of the video input must match that of the video output.
1167 So it is not possible to loop a 50 Hz (720x576) S-Video output to a 60 Hz
1168 (720x480) S-Video input, or a 720p60 HDMI output to a 1080p30 input.
1176 Bottom' when the output video is set to 'Field Alternate'. This combination,
1187 - on the input side the "Standard Signal Mode" for the S-Video input or the
1189 valid signal is passed to the video input.
1195 By default you will see the OSD text superimposed on top of the looped video.
1196 This can be turned off by changing the "OSD Text Mode" control of the video

1285 Video output will also honor any data_offset that the application set.

1317 capabilities will slow down the video loop considerably as a lot of checks have
1347 - Some support for testing compressed video
1350 - Fix sequence/field numbering when looping of video with alternate fields
1351 - Add support for V4L2_CID_BG_COLOR for video outputs
