u64 is aligned as 128bits on x86_64 architetures, requiring an special
handling to ioctls that depends on v4l2_ext_control.
Let's fix this before ext controls go to kernel mainstream to avoid one
more compat32 stuff.Signed-off-by: Mauro Carvalho Chehab

V4L2_CID_MPEG_STREAM_VBI_FMT controls if and how VBI data is embedded in
an MPEG stream. Currently only one format is supported: the format designed
for the ivtv driver. This should be extended with new standard formats
(such as defined for DVB) in the future.Signed-off-by: Hans Verkuil

HM12 is a YUV 4:1:1 format used by the cx2341x MPEG encoder/decoder for
the raw YUV input/output. The Y and UV planes are broken up in 16x16
macroblocks and each macroblock is transmitted in turn (row by row).Signed-off-by: Hans Verkuil

The zoran driver uses strncpy() in an unsafe way. This patch uses the proper
sizeof()-1 size parameter. Since all strncpy() targets are initialised with
memset() the trailing '\0' is already set. Where std->name was the target for
the strncpy() we overwrote 8 Bytes of the std structure with zeros.Signed-off-by: Eric Sesterhenn

The videodev.h and videodev2.h describe the public API for V4L and V4L2.
It shouldn't have there any kernel-specific stuff. Those were moved to
v4l2-dev.h.
This patch removes some uneeded headers and include v4l2-common.h on all
V4L driver. This header includes device implementation of V4L2 API provided
on v4l2-dev.h as well as V4L2 internal ioctls that provides connections
between master driver and its i2c devices.Signed-off-by: Mauro Carvalho Chehab

Videodev now is capable of better handling V4L2 api, by

linux/videodev2.h uses types such as __u8 but it fails to include
. Within the kernel, that's not a problem because
already includes . However, there are
user apps that try to include videodev2.h (e.g., ekiga) and at least
on ia64, it causes compilation failures since doesn't
get included for any other reason, leaving __u8 etc. undefined. The
attached patch fixes the problem for me.Signed-off-by: Andrew Morton

V4L1 API is depreciated and should be removed soon from kernel. This patch
adds two new options, one to disable V4L1 drivers, and another to disable
V4L1 compat module. This way, it would be easy to check what still depends
on V4L1 stuff, allowing also to test if app works fine with V4L2 only support.Signed-off-by: Mauro Carvalho Chehab

Add a new audio mode V4L2_TUNER_MODE_LANG1_LANG2 (used by VIDIOC_G/S_TUNER).
This mode allows the user to select both languages of a bilingual transmission,
one language on the left, one on the right audio channel. If there is no
bilingual transmission, or it is not supported, then this mode should act like
V4L2_TUNER_MODE_STEREO.
This mode is introduced for PVR-like drivers where it is useful to be able to
record both languages of a bilingual broadcast.Signed-off-by: Hans Verkuil

This moves the 32 bit ioctl compatibility handlers for
Video4Linux into a new file and adds explicit calls to them
to each v4l device driver.Unfortunately, there does not seem to be any code handling
the v4l2 ioctls, so quite often the code goes through two
separate conversions, first from 32 bit v4l to 64 bit v4l,
and from there to 64 bit v4l2. My patch does not change
that, so there is still much room for improvement.Also, some drivers have additional ioctl numbers, for
which the conversion should be handled internally to
that driver.Signed-off-by: Arnd Bergmann

Adds all defines, ioctls and structs needed for the sliced VBI API
VBI = Vertical Blank Interval.
It is related with the way TV signals work. It sends a line, then, it has a
retrace time to allow the tube to move electrons to the beginning of the next
line. This was the main reason at the beginning of analog B&W TV.There is a lot of bandwidth lost on VBI. So, lots of TV systems use it to
send other information such as Closed Captions and Teletext. Also,
broadcasters uses this as a channel to exchange information from the content
producer to their subsidiaries at each city.There's already a raw VBI interface on V4L2 api, used for Closed Captions and
Teletext. The decoding is doing at userlevel space and it is mostly for
analog TV signals, non encoded.Encoded signals (MPEG, for example), may need also to transmit other
information (like, for example, display aspect, i.e. 4x3, widescreen...).
Sliced VBI interface is a method to allow the video stream to transmit this
kind of information.Signed-off-by: Hans Verkuil
