I'm working on the V4L2 DocBook spec and when reading through the "Device
Naming"
subsection of the "Opening and Closing Devices" section in the first chapter I
realized that it is really out of date. The text is in this file:
Documentation/DocBook/v4l/common.xml
With udev pretty much everything in that section is useless (and probably
confusing
for first-time readers).
I propose that we replace it with something short like this:
-----------------------------------------------------
Device Naming
V4L2 drivers create one or more device nodes with major number 81 and a minor
number
between 0 and 255. Three types of devices can be created:
/dev/videoX Used for video capture/output/overlay.
/dev/radioX Used for radio and RDS tuning/modulating.
/dev/vbiX Used for VBI capture and output.
-----------------------------------------------------
Is there anything else that should be in here?
BTW, I'm working on editing the 'Related Devices', 'Multiple Opens' and
'Shared Data Streams' as well.
Regards,
Hans
