Fix compilation of user processes which includes videodev*.h but not includes linux/ioctl.h: v4l2ext_helper.c: In function 'process_ioctl': v4l2ext_helper.c:183: warning: implicit declaration of function '_IOWR' v4l2ext_helper.c:183: error: expected expression before 'struct' v4l2ext_helper.c:183: error: case label does not reduce to an integer constant Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-22V4L/DVB (6321): Remove obsolete VIDIOC_S/G_MPEGCOMP ioctlsHans Verkuil
Remove the obsolete VIDIOC_G_MPEGCOMP and VIDIOC_S_MPEGCOMP ioctls from the V4L2 API as per the removal schedule (October 2007). Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-10-09V4L/DVB (6108): videodev2.h: add new pixel formats for the cx23415 OSDHans Verkuil
The Conexant cx23415 MPEG encoder/decoder supports some unusual pixelformats for the On-Screen Display. Add new defines to videodev2.h for these formats. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-08-20V4L/DVB (5968): videodev2.h: remove superfluous FBUF GLOBAL_INV_ALPHA supportHans Verkuil
There is no need for a global inverted alpha capability since all the application has to do is to pass '255-alpha' as the global alpha value. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-07-20V4L/DVB (5867): videodev2.h: add missing <sys/time.h> for userspaceHans Verkuil
When videodev2.h is included by an application, it needs to include <sys/time.h> for the timeval struct. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-06-08V4L/DVB (5736): Add V4L2_FBUF_CAP/FLAG_LOCAL/GLOBAL_INV_ALPHAHans Verkuil
Michael Schimek requested the addition of inverted alpha framebuffer caps/flags to support such hardware. 'Normal' alpha uses this formula to mix the framebuffer and video: output = fb pixel * fb alpha + video pixel * (1 - fb alpha) and the 'inverted' alpha uses this formula: output = fb pixel * (1 - fb alpha) + video pixel * fb alpha Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-06-08V4L/DVB (5730): Remove unused V4L2_CAP_VIDEO_OUTPUT_POSHans Verkuil
V4L2_CAP_VIDEO_OUTPUT_POS was initially introduced for 2.6.22 but never actually used: remove it before the final 2.6.22 is made. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-05-22V4L/DVB (5670): Adding new fields to v4l2_pix_format broke the ABI, reverted ↵Hans Verkuil
that change Reverted the change to struct v4l2_pix_format. I completely missed that this struct was used by existing ioctls so that changing it broke the ABI. I will have to think of another way of setting the top/left coordinates but for now this change is reverted to preserve compatibility.

2007-04-27V4L/DVB (5306): Add support for VIDIOC_G_CHIP_IDENTHans Verkuil
VIDIOC_G_CHIP_IDENT improves debugging of card problems: it can be used to detect which chips are on the board and based on that information selected register dumps can be made, making it easy to debug complicated media chips containing tens or hundreds of registers. This ioctl replaces the internal VIDIOC_INT_G_CHIP_IDENT ioctl. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5289): Add support for video output overlays.Hans Verkuil
Add V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY support. Also add support for local and global alpha overlays. Add new field enums V4L2_FIELD_INTERLACED_TB and V4L2_FIELD_INTERLACED_BT. These changes are needed to support the ivtv On Screen Display features. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5272): Add V4L2_CAP_VIDEO_OUTPUT_POS capabilityHans Verkuil
Add V4L2_CAP_VIDEO_OUTPUT_POS capability and x, y position coordinates to struct v4l2_pix_format. This is needed to support positioning the MPEG/YUV output of the cx23415. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-04-27V4L/DVB (5268): Add support for three new MPEG controls.Hans Verkuil
Added V4L2_CID_MPEG_AUDIO_MUTE, V4L2_CID_MPEG_VIDEO_MUTE and V4L2_CID_MPEG_CX2341X_STREAM_INSERT_NAV_PACKETS controls together with their implementation in the cx2341x module. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-03-01V4L/DVB (5305): Mark VIDIOC_DBG_S/G_REGISTER as experimentalHans Verkuil

2007-03-01V4L/DVB (5304): Improve chip matching in v4l2_registerHans Verkuil
The chip matching in struct v4l2_register for VIDIOC_DBG_G/S_REGISTER was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5204): Change videodev2.h licence to dual GPL/BSDMichael Schimek
videodev2.h contains just the V4L2 API structs and defines. By allowing this header file to be dual GPL/BSD will enable sharing userspace apps between Linux and *BSD systems. It will also allow developing newer BSD licensed drivers that can be shared on Linux and *BSD. It should be noticed that most of the current V4L drivers, and v4l core itself are GPL only. This won't be changed by this patch. Signed-off-by: Michael H.

2007-02-21V4L/DVB (5182): Remove #if 0 section from videodev2.hHans Verkuil
Remove a section containing basically ideas for future sliced VBI standards. This can be resurrected should any of this be actually implemented. For now it only pollutes this header file. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5181): Sliced VBI API no longer marked experimental.Hans Verkuil
The Sliced VBI API is no longer marked experimental. Introduced in 2.6.14 and with only a single modification in 2.6.19 I think we can consider this API to be solid. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5162): Change VIDIOC_DBG_[SG]_REGISTER ioctls' reg address to 64 bitsTrent Piepho
Maybe someday there will be a device with a register address space > 32-bits, or maybe an i2c device which uses a protocol > 4 bytes long to address its registers. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21V4L/DVB (5068): Fix authorship referencesMauro Carvalho Chehab
Bill Dirks asked me to update his entries at kernel files, since he change his e-mail. I've also updated a few web broken links or obsolete info to the curent sites where V4L drivers and API are being discussed currently.

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>
2006-10-03V4L/DVB (4672): Frame format enumeration (1/2)Laurent Pinchart

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
It's better to use explicit enums. It reduces the chance of someone inserting new enums in the middle which would break things. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-06-25V4L/DVB (4198): Avoid newer usages of obsoleted experimental MPEGCOMP APIHans Verkuil

2006-06-25V4L/DVB (4188): Add new MPEG control/ioctl definitions to videodev2.hHans Verkuil
The old, experimental, VIDIOC_S/G_CODEC API to pass MPEG parameters is now obsolete and is replaced by 'extended controls' which offer more flexibility and are hopefully more future proof. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
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. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
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>

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.
