* [media] vivid: use consistent colorspace/Y'CbCr Encoding stringsHans Verkuil2015-02-02
| | | | | | | | Keep the colorspace and encoding names consistent with what is used elsewhere (primarily the utilities in v4l-utils.git). Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: Y offset should depend on quant. rangeHans Verkuil2015-01-29
| | | | | | | | | | When converting to or from Y'CbCr and R'G'B' the Y offset depends on the quantization range: it's 0 for full and 16 for limited range. But in the code it was hardcoded to 16. This messed up the brightness of the generated pattern. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] vivid: fix CROP_BOUNDS typo for video outputHans Verkuil2014-12-16
| | | | | | | | | | | An error was returned if composing was not supported, instead of if cropping was not supported. A classic copy-and-paste bug. Found with v4l2-compliance.

* [media] vivid: add support for YCbCr encoding and quantizationHans Verkuil2014-12-02
| | | | | | | | Implement controls to set the YCbCr encoding and the quantization range for the colorspace. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: add new colorspacesHans Verkuil2014-12-02
| | | | | | | | | | | Add AdobeRGB and BT.2020 support. The colorspace control now orders the colorspaces according to how often they are used. So rarely used colorspaces are moved to the end. This makes it more logical when testing colorspace support. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid-tpg: improve colorspace supportHans Verkuil2014-12-02
| | | | | | | | Add support for the new AdobeRGB and BT.2020 colorspaces. Also support explicit Y'CbCr and quantization settings. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid-tpg-colors: add AdobeRGB and BT.2020 supportHans Verkuil2014-12-02
| | | | | | | | | | | | This extends the precalculated tpg_csc_colors matrix with AdobeRGB and BT.2020 colorspace support. It also adds two precalculated tables that convert between linear RGB and non-linear Rec.709 R'G'B' values, i.e. the Rec. 709 transfer function. This is needed to efficiently handle the BT.2020 Constant Luminance Yc'CbcCrc encoding and decoding.

* [media] vivid: enable vb2_expbuf supportHans Verkuil2014-11-25
| | | | | | | | | Now that vb2 supports DMABUF export for dma-sg and vmalloc memory modes, we can enable the vb2_expbuf support in vivid. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Reviewed-by: Pawel Osciak <pawel@osciak.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] vivid: add test array controlsHans Verkuil2014-11-11
| | | | | | | | | | | | Add array controls to test support for such controls. There is one array with just one element, one 8x16 matrix control and one 4 dimensional 2x3x4x5 control. This makes it possible to experiment with such controls without requiring hard-to-get hardware.

* [media] vivid: default to single planar device instancesHans Verkuil2014-11-03
| | | | | | | | | | | The default used to be that the first vivid device instance was single planar, the second multi planar, the third single planar, etc. However, that turned out to be unexpected and awkward. Change the driver to always default to single planar. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: fix buffer overrunHans Verkuil2014-10-21
| | | | | | | | | | | The random_line buffer must be twice the maximum width, but it only allocated the maximum width, so it was only half the size it needed to be. Surprisingly I never saw the kernel fail on this, but the same TPG code used in qv4l2 crashed and valgrind helped me track this bug down.

* [media] vivid: add teletext support to VBI captureHans Verkuil2014-09-21
| | | | | | | | | | | This is useful to test teletext capture applications like alevt and mtt. It also fixes a previously undetected bug where the PAL VBI start line of the second field was off by one. Using the new field start defines helps a lot fixing such bugs.

* [media] vivid-vid-out: use memdup_user()Mauro Carvalho Chehab2014-09-03

* [media] vivid: add support for radio receivers and transmittersHans Verkuil2014-09-02
| | | | | | | | | | | This adds radio receiver and transmitter support. Part of that is common to both and so is placed in the radio-common source. These drivers also support RDS. In order to generate valid RDS data a simple RDS generator is implemented in rds-gen. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] vivid: add the Test Pattern GeneratorHans Verkuil2014-09-02

* [media] vivid: add a simple framebuffer device for overlay testingHans Verkuil2014-09-02

* [media] vivid: add the kthread code that controls the video rateHans Verkuil2014-09-02
| | | | | | | | | | | | | | | | | Add the kthread handlers for video/vbi capture and video/vbi output. These carefully control the rate at which frames are generated (video capture) and accepted (video output). While the short-term jitter is around the order of a jiffie, in the long term the rate matches the configured framerate exactly. The capture thread handler also takes care of the video looping and of capture and overlay support. This is probably the most complex part of this driver due to the many combinations of crop, compose and scaling on the input and output, and the blending that has to be done if overlay support is enabled as well.

* [media] vivid: add VBI capture and output codeHans Verkuil2014-09-02
