2017-04-14[media] v4l: Clearly document interactions between formats, controls and buffersLaurent Pinchart
V4L2 exposes parameters that influence buffers sizes through the format ioctls (VIDIOC_G_FMT, VIDIOC_TRY_FMT, VIDIOC_S_FMT, and possibly VIDIOC_G_SELECTION and VIDIOC_S_SELECTION). Other parameters not part of the format structure may also influence buffer sizes or buffer layout in general. One existing such parameter is rotation, which is implemented by the V4L2_CID_ROTATE control and thus exposed through the V4L2 control ioctls. The interaction between those parameters and buffers is currently only partially specified by the V4L2 API. In particular interactions between controls and buffers isn't specified at all. The behaviour of the VIDIOC_S_FMT and VIDIOC_S_SELECTION ioctls when buffers are allocated is also not fully specified. This patch clearly defines and documents the interactions between formats, selections, controls and buffers. The preparatory discussions for the documentation change considered completely disallowing controls that change the buffer size or layout, in favour of extending the format API with a new ioctl that would bundle those controls with format information. The idea has been rejected, as this would essentially be a restricted version of the upcoming request API that wouldn't bring any additional value. Another option we have considered was to mandate the use of the request API to modify controls that influence buffer size or layout. This has also been rejected on the grounds that requiring the request API to change rotation even when streaming is stopped would significantly complicate implementation of drivers and usage of the V4L2 API for applications. Applications will however be required to use the upcoming request API to change at runtime formats or controls that influence the buffer size or layout, because of the need to synchronize buffers with the formats and controls. Otherwise there would be no way to interpret the content of a buffer correctly.

2017-04-10[media] dev-capture.rst/dev-output.rst: video standards ioctls are optionalHans Verkuil
The documentation for video capture and output devices claims that the video standard ioctls are required. This is not the case, they are only required for PAL/NTSC/SECAM type inputs and outputs. Sensors do not implement this at all and e.g. HDMI inputs implement the DV Timings ioctls. Just drop the mention of 'video standard' ioctls.

2017-03-22[media] videodev2.h: map xvYCC601/709 to limited range quantizationHans Verkuil
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.

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.

2017-01-30[media] rc: change wakeup_protocols to list all protocol variantsSean Young
For IR wakeup, a driver has to program the hardware to wakeup at a specific IR sequence, so it makes no sense to allow multiple wakeup protocols to be selected. In the same manner the sysfs interface only allows one scancode to be provided. In addition, we need to know the specific variant of the protocol. In short, these changes are made to the wakeup_protocols sysfs entry: - list all the protocol variants rather than the protocol groups, e.g. "nec nec-x nec-32" rather than just "nec". - only allow one protocol variant to be selected rather than multiple - wakeup_filter can only be set once a protocol has been selected in wakeup_protocols. This is an API change, however the only user of this API is the img-ir, but the wakeup code was never merged to mainline, so it was never used.

2016-11-30docs-rst: replace the selection.png by a SVG imageMauro Carvalho Chehab
bitmap images don't scale too well. So, replace it by a SVG image, written in inkscape. I'm using the 2009's temporary logo.svg image from 8032b526d1a3 ("linux.conf.au 2009: Tuz"), with a Tasmanian Devil wearing a tux mask.

2016-11-30docs-rst: convert pipeline to SVG formatMauro Carvalho Chehab
The pipeline image was produced from some dot file that has long missed. Create a pipeline.dot with the graph and convert it to SVG. As we're planning to add future support for graphviz graphics, also store the .dot file on the tree, as this will make easier when we add such Sphinx extension.

2016-11-30svg files: cleanup themMauro Carvalho Chehab

2016-11-30convert more media images to SVGMauro Carvalho Chehab
Using vectorial graphics provide a better visual. As those images are originally using a vectorial graphics input at the pdf files, use them, from an old media tree repository, converting them to SVG.

The formats added by this patch are: V4L2_PIX_FMT_SBGGR16 V4L2_PIX_FMT_SGBRG16 V4L2_PIX_FMT_SGRBG16 V4L2_PIX_FMT_SRGGB16 already existed before the patch.

2016-11-16docs-rst: auto-generate PDF image filesMauro Carvalho Chehab
The PDF files that contain media images were actually generated offline from their SVG or PNG source files. Sphinx can handle PNG sources automatially. So, let's just drop their PDF counterparts. For SVG, however, Sphinx doesn't produce the right tags to use the TexLive SVG support. Also, the SVG support is done via shell execution, with is not nice. So, while we don't have any support for SVG inside Sphinx core or as an extension, move the logic to build them to Makefile, producing the PDF images on runtime. NOTE: due to the way Sphinx works, the PDF images should be generated inside the Kernel source tree, as otherwise Sphinx won't find it, not obeying what's specified by "O=" makefile parameter.

2016-11-16docs-rst: convert gif files to pngMauro Carvalho Chehab
Right now, media is using two different formats for bitmap images: GIF and PNG. Let's use just one, to make it simpler when building with Sphinx. As PNG is usually better than GIF, let's use it.
