2007-01-15V4L/DVB (5023): Fix compilation on ppc32 architectureMauro Carvalho Chehab
There's a problem, pointed by Meelis Roos <mroos@linux.ee>, that, on ppc32 arch, with some gcc versions (noticed with prerelease 4.1.2 20061115), compilation fails, due the lack of __ucmpdi2 to do the required 64-bit comparision. This patch takes some sugestions made by Andrew Morton <akpm@osdl.org>, Stelian Pop <stelian@popies.net> and Segher Boessenkool <segher@kernel.crashing.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-10-03V4L/DVB (4673): Mark the two newer ioctls as experimentalMauro Carvalho Chehab
VIDIOC_ENUM_FRAMESIZES and VIDIOC_ENUM_FRAMEINTERVALS ioctls are meant to be used to provide better support for webcams. Currently, it is not yet used on kernel drivers. Better to keep it marked as experimental, until we have several kernel drivers supporting those features. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-09-26V4L/DVB (4585): VIDIOC_G_SLICED_VBI_CAP now accepts a v4l2_buf_type, make it ↵Hans Verkuil
IOWR The VIDIOC_G_SLICED_VBI_CAP needs to receive the v4l2_buf_type field before it can return a result. Hence this ioctl must be IOWR, not IOR. Since this ioctl is still marked experimental we can make this change. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-09-10V4L/DVB (4605): Fixes an issue with V4L1 and make headers-installMauro Carvalho Chehab
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.

2006-07-29V4L/DVB (4342): Fix ext_controls align on 64 bit architecturesMauro Carvalho Chehab
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 <mchehab@infradead.org>
2006-06-26V4L/DVB (4223): Add V4L2_CID_MPEG_STREAM_VBI_FMT controlHans Verkuil
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.

2006-06-26V4L/DVB (4221): Add HM12 YUV format define.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).

2006-06-25V4L/DVB (4203): Explicitly set the enum values.Hans Verkuil

2006-06-25V4L/DVB (4188): Add new MPEG control/ioctl definitions to videodev2.hHans Verkuil

2006-06-25V4L/DVB (4108): Fixes some userspace dependencies at V4L2 public api headerMauro Carvalho Chehab

2006-06-25V4L/DVB (4070): Zoran strncpy() fixEric Sesterhenn
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.

2006-06-25V4L/DVB (4068): Removed all references to kernel stuff from videodev.h and ↵Mauro Carvalho Chehab
videodev2.h 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.

2006-06-25V4L/DVB (4065): Several improvements at videodev.cMauro Carvalho Chehab
Videodev now is capable of better handling V4L2 api, by processing V4L2 ioctls and using callbacks to the driver. The drivers should be migrated to the newer way and the older one will be obsoleted soon. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-06-25V4L/DVB (4046): Trivial videodev2.h patchDavid Mosberger-Tang
linux/videodev2.h uses types such as __u8 but it fails to include <linux/types.h>. Within the kernel, that's not a problem because <linux/time.h> already includes <linux/types.h>. However, there are user apps that try to include videodev2.h (e.g., ekiga) and at least on ia64, it causes compilation failures since <linux/types.h> 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 <akpm@osdl.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-05-12V4L/DVB (3774): Create V4L1 config optionsMauro Carvalho Chehab
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 <mchehab@infradead.org>

2006-03-24V4L/DVB (3584): Implement V4L2_TUNER_MODE_LANG1_LANG2 audio modeHans Verkuil
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.

2006-01-09V4L (926_2): Moves compat32 functions from fs to v4l subsystemArnd Bergmann
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.

2005-09-13[PATCH] v4l: experimental Sliced VBI API supportMauro Carvalho Chehab
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.
