* [media] vivid: use V4L2_DV_FL_IS_CE_VIDEO instead of V4L2_DV_BT_STD_CEA861Hans Verkuil2015-04-08
| | | | | | | | Don't rely on V4L2_DV_BT_STD_CEA861 since that include the 640x480p format, which is an IT format, not CE. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: allow s_dv_timings if it is the same as the currentHans Verkuil2015-04-02
| | | | | | | | | | | Allow setting the same timings as the current timings (i.e., do nothing in that case). The code was actually there, but the vb2_is_busy() call was done before the timings check instead of afterwards. Found by v4l2-compliance.

* [media] vivid: add downsampling supportHans Verkuil2015-04-02
| | | | | | | | Add support in vivid for downsampling. Most of the changes are in vivid_copy_buffer which needs to know about the right line widths. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: add support for single buffer planar formatsHans Verkuil2015-04-02
| | | | | | | | Make vivid aware of the difference of planes and buffers. Note that this does not yet add support for hor/vert downsampled formats. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] vivid: add new format fieldsHans Verkuil2015-04-02
| | | | | | | These fields are necessary to handle the new planar formats. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
* [media] drivers: media: platform: vivid: Fix possible null derefrenceTapasweni Pathak2015-04-02
| | | | | | | | | | | | Check for dev_fmt being null before derefrencing it, to assign it to planes. Found using Coccinelle.

* [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 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: remove duplicate and unused g/s_edid functionsHans Verkuil2014-09-08
| | | | | | | I'm not sure how I missed this, but they should be removed. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] vivid-vid-out: use memdup_user()Mauro Carvalho Chehab2014-09-03
| | | | | | | | | | Instead of allocating and coping from __user, do it using one atomic call. That makes the code simpler. Found by coccinelle. Acked-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
* [media] vivid: comment the unused g_edid/s_edid functionsMauro Carvalho Chehab2014-09-02
| | | | | | | | | | | | | | | | | Those non-static functions aren't used anywhere yet. Comment them while they're unused.

* [media] vivid: add the video capture and output partsHans Verkuil2014-09-02
This adds the ioctl and vb2 queue support for video capture and output. Part of this is common to both, so that is placed in a vid-common source. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
