V4L1 support should be disabled when no CONFIG_VIDEO_V4L1_COMPAT is defined, to allow checking for broken V4L2 ports. This is very important during the migration phase for V4L2 API. However, userspace apps should be capable of using both APIs, since they need to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when __KERNEL__ is not defined, those ioctls and corresponding structs should be visible. This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT and CONFIG_VIDEO_V4L2.

Support for audio/video capture and overlay devices and FM radio

cards. The exact capabilities of each device vary.

This kernel includes support for the new Video for Linux Two API,
|
|
(V4L2) as well as the original system. Drivers and applications
|
|
need to be rewritten to use V4L2, but drivers for popular cards
|
|
and applications for most video capture functions already exist.

This api were developed to be used at Kernel 2.2 and 2.4, but

lacks support for several video standards. There are several

drivers at kernel that still depends on it.
