* License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman2017-11-021-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

* [media] videodev2.h: map xvYCC601/709 to limited range quantizationHans Verkuil2017-03-221-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The xvYCC601/709 encodings were mapped by default to full range quantization. This is actually wrong since these encodings use limited range quantization, but accept values outside of the limited range. This makes sense since for values within the limited range it behaves exactly the same as BT.601 or Rec. 709. The only difference is that with the xvYCC encodings the values outside of the limited range also produce value colors. Talking to people who know a lot more about this than I do made me realize that mapping xvYCC to full range quantization was wrong, so this patch corrects this and also improves the documentation. These formats are very rare, and since the formula for decoding these Y'CbCr encodings is actually fixed and independent of the quantization field value it is safe to make this change. The main advantage is that keeps the V4L2 specification in sync with the corresponding colorspace, HDMI and CEA861 standards when it comes to these xvYCC formats.

* [media] videodev2.h: go back to limited range Y'CbCr for SRGB and, ADOBERGBHans Verkuil2017-02-131-4/+3
| | | | | | | | | | | | | | | | | | | | This reverts 'commit 7e0739cd9c40 ("[media] videodev2.h: fix sYCC/AdobeYCC default quantization range"). The problem is that many drivers can convert R'G'B' content (often from sensors) to Y'CbCr, but they all produce limited range Y'CbCr. To stay backwards compatible the default quantization range for sRGB and AdobeRGB Y'CbCr encoding should be limited range, not full range, even though the corresponding standards specify full range. Update the V4L2_MAP_QUANTIZATION_DEFAULT define accordingly and also update the documentation.

* [media] videodev2.h: add VICs and picture aspect ratioHans Verkuil2016-11-161-2/+25
| | | | | | | | | | | | | | | Add picture aspect ratio information, the CEA-861 VIC (Video Identification Code) and the HDMI VIC to struct v4l2_bt_timings. The picture aspect was chosen rather than the pixel aspect since 1) the CEA-861 standard uses picture aspect, and 2) pixel aspect ratio can become tricky when dealing with pixel repeat timings. While we don't support those yet at the moment, this might become necessary. And in that case using picture aspect ratio makes more sense. And converting picture aspect ratio to pixel aspect ratio is easy enough. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

* [media] videodev2.h: fix copy-and-paste error in V4L2_MAP_XFER_FUNC_DEFAULTHans Verkuil2015-06-181-1/+1
| | | | | | | | The colorspace argument was compared against a V4L2_XFER_FUNC define instead of against a V4L2_COLORSPACE define, returning the wrong answer. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] videodev2.h: add support for transfer functionsHans Verkuil2015-06-051-1/+40
| | | | | | | | | | | | | In the past the transfer function was implied by the colorspace. However, it is an independent entity in its own right. Add support for explicitly choosing the transfer function. This change will allow us to represent linear RGB (as is used by openGL), and it will make it easier to work with decoded video material since most codecs store the transfer function as a separate property as well.

* [media] videodev2.h: add macros to map colorspace defaultsHans Verkuil2015-05-301-0/+30
| | | | | | | | | | | | The mapping of COLORSPACE_DEFAULT, YCBCR_ENC_DEFAULT or QUANTIZATION_DEFAULT to proper non-default values is fairly complex, and it is something that needs to be done both in the kernel and in userspace. So add macros that can do this conversion, making this available to both kernel and userspace.

* [media] videodev2.h: add COLORSPACE_RAWHans Verkuil2015-05-301-0/+3
| | | | | | | | | | | V4L2_COLORSPACE_RAW is added for raw image formats where the picture is minimally processed and is in the internal colorspace of the sensor. This is typically used in digital cameras where the image processing is done later. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] videodev2.h: add COLORSPACE_DEFAULTHans Verkuil2015-05-301-0/+6
| | | | | | | | | | | | V4L2_COLORSPACE_DEFAULT is added so we have a specific define for the default case where applications do not set it but leave it to 0. In that case the driver will set the colorspace based on what it captures. This is already used, but we never had a define for the value 0.

* [media] videodev2.h/v4l2-dv-timings.h: add V4L2_DV_FL_IS_CE_VIDEO flagHans Verkuil2015-04-081-0/+6
| | | | | | | | | | | | | | | | | | | | In the past the V4L2_DV_BT_STD_CEA861 standard bit was used to determine whether the format is a CE (Consumer Electronics) format or not. However, the 640x480p59.94 format is part of the CEA-861 standard, but it is *not* a CE video format. Add a new flag to make this explicit. This information is needed in order to determine the default R'G'B' encoding for the format: for CE video this is limited range (16-235) instead of full range (0-255). The header with all the timings has been updated with this new flag.
