4 This driver emulates video4linux hardware of various types: video capture, video
27 - Support for various pixel aspect ratios and video aspect ratios
83 By default the driver will create a single instance that has a video capture
84 device with webcam, TV, S-Video and HDMI inputs, a video output device with

152 vid_cap_nr: give the desired videoX start number for each video capture device.
154 you to map capture video nodes to specific videoX device nodes. Example:

181 ccs_cap_mode: specify the allowed video capture crop/compose/scaling combination
204 ccs_out_mode: specify the allowed video output crop/compose/scaling combination
255 This is probably the most frequently used feature. The video capture device
313 The pixel aspect ratio will depend on the TV standard. The video aspect ratio
315 Choices are '4x3', '16x9' which will give letterboxed widescreen video and
317 video that will need to be scaled accordingly.
358 The video aspect ratio can be selected through the 'DV Timings Aspect Ratio'
361 result in pillarboxed or letterboxed video.
373 The video output device can be configured by using the module options
379 Like with video capture the framerate is also exact in the long term.
535 The following controls are specific to video capture.
539 video input has its own brightness value, so changing input will restore
540 the brightness for that input. In addition, each video input uses a different

872 The vivid driver supports looping of video output to video input, VBI output
873 to VBI input and RDS output to RDS input. For video/VBI looping this emulates
874 as if a cable was hooked up between the output and input connector. So video
889 The way to enable video/VBI looping is currently fairly crude. A 'Loop Video'
890 control is available in the "Vivid" control class of the video
891 output and VBI output devices. When checked the video looping will be enabled.
892 Once enabled any video S-Video or HDMI input will show a static test pattern
893 until the video output has started. At that time the video output will be
894 looped to the video input provided that:
897 video from the S-Video output.
899 - the video resolution of the video input must match that of the video output.
909 Bottom' when the output video is set to 'Field Alternate'. This combination,
922 valid signal is passed to the video input.
926 By default you will see the OSD text superimposed on top of the looped video.
927 This can be turned off by changing the "OSD Text Mode" control of the video

1099 capabilities will slow down the video loop considerably as a lot of checks have
1110 - Some support for testing compressed video
1113 - Fix sequence/field numbering when looping of video with alternate fields
1114 - Add support for V4L2_CID_BG_COLOR for video outputs
