Document administration details about CEC devices. This was formerly
documented in a cec-status.txt I kept on my website, but this really
belongs here as an admin guide.

Updated the original cec-status.txt, and converted it to .rst.

media: visl: add virtual stateless decoder driver

2022-11-25T07:32:16+00:00

A virtual stateless device for stateless uAPI development purposes.

This tool's objective is to help the development and testing of
userspace applications that use the V4L2 stateless API to decode media.

A userspace implementation can use visl to run a decoding loop even when
no hardware is available or when the kernel uAPI for the codec has not
been upstreamed yet. This can reveal bugs at an early stage.

This driver can also trace the contents of the V4L2 controls submitted
to it.  It can also dump the contents of the vb2 buffers through a
debugfs interface. This is in many ways similar to the tracing
infrastructure available for other popular encode/decode APIs out there
and can help develop a userspace application by using another (working)
one as a reference.

Note that no actual decoding of video frames is performed by visl. The
V4L2 test pattern generator is used to write various debug information
to the capture buffers instead.

media: vivid.rst: loop_video is set on the capture devnode

2022-10-25T15:43:54+00:00

The example on how to use and test Capture Overlay specified
the wrong video device node. Back in 2015 the loop_video control
moved from the output device to the capture device, but this
example code is still referring to the output video device.
