The differences between Annex A and Annex C is that Annex C uses a subset of the modulation types, and uses a different rolloff factor. A different rolloff means that the bandwidth required is slicely different, and may affect the saw filter configuration at the tuners. Also, some demods have different configurations, depending on using Annex A or Annex C. So, allow userspace to specify it, by changing the rolloff factor.

+ + Experimental API for cropping, composing and scaling + + + Experimental + + This is an experimental +interface and may change in the future. + + +
+ Introduction + +Some video capture devices can sample a subsection of a picture and +shrink or enlarge it to an image of arbitrary size. Next, the devices can +insert the image into larger one. Some video output devices can crop part of an +input image, scale it up or down and insert it at an arbitrary scan line and +horizontal offset into a video signal. We call these abilities cropping, +scaling and composing. + +On a video capture device the source is a video +signal, and the cropping target determine the area actually sampled. The sink +is an image stored in a memory buffer. The composing area specifies which part +of the buffer is actually written to by the hardware. + +On a video output device the source is an image in a +memory buffer, and the cropping target is a part of an image to be shown on a +display. The sink is the display or the graphics screen. The application may +select the part of display where the image should be displayed. The size and +position of such a window is controlled by the compose target. + +Rectangles for all cropping and composing targets are defined even if the +device does supports neither cropping nor composing. Their size and position +will be fixed in such a case. If the device does not support scaling then the +cropping and composing rectangles have the same size. + +
+ +
+ Selection targets + +
+ Cropping and composing targets + + + + + + Targets used by a cropping, composing and scaling + process + + +
+
+ +
+ + Configuration + +Applications can use the selection +API to select an area in a video signal or a buffer, and to query for +default settings and hardware limits. + +Video hardware can have various cropping, composing and scaling +limitations. It may only scale up or down, support only discrete scaling +factors, or have different scaling abilities in the horizontal and vertical +directions. Also it may not support scaling at all. At the same time the +cropping/composing rectangles may have to be aligned, and both the source and +the sink may have arbitrary upper and lower size limits. Therefore, as usual, +drivers are expected to adjust the requested parameters and return the actual +values selected. An application can control the rounding behaviour using constraint flags . + +
+ + Configuration of video capture + +See figure for examples of the +selection targets available for a video capture device. It is recommended to +configure the cropping targets before to the composing targets. + +The range of coordinates of the top left corner, width and height of +areas that can be sampled is given by the V4L2_SEL_TGT_CROP_BOUNDS + target. It is recommended for the driver developers to put the +top/left corner at position (0,0) . The rectangle's +coordinates are expressed in driver dependant units, although the coordinate +system guarantees that if sizes of the active cropping and the active composing +rectangles are equal then no scaling is performed. + +The top left corner, width and height of the source rectangle, that is +the area actually sampled, is given by the V4L2_SEL_TGT_CROP_ACTIVE + target. It uses the same coordinate system as +V4L2_SEL_TGT_CROP_BOUNDS . The active cropping area must lie +completely inside the capture boundaries. The driver may further adjust the +requested size and/or position according to hardware limitations. + +Each capture device has a default source rectangle, given by the + V4L2_SEL_TGT_CROP_DEFAULT target. This rectangle shall +over what the driver writer considers the complete picture. Drivers shall set +the active crop rectangle to the default when the driver is first loaded, but +not later. + +The composing targets refer to a memory buffer. The limits of composing +coordinates are obtained using V4L2_SEL_TGT_COMPOSE_BOUNDS +. All coordinates are expressed in natural unit for given formats. +Pixels are highly recommended. The rectangle's top/left corner must be located +at position (0,0) . The width and height are equal to the +image size set by VIDIOC_S_FMT . + +The part of a buffer into which the image is inserted by the hardware is +controlled by the V4L2_SEL_TGT_COMPOSE_ACTIVE target. +The rectangle's coordinates are also expressed in the same coordinate system as +the bounds rectangle. The composing rectangle must lie completely inside bounds +rectangle. The driver must adjust the composing rectangle to fit to the +bounding limits. Moreover, the driver can perform other adjustments according +to hardware limitations. The application can control rounding behaviour using + constraint flags . + +For capture devices the default composing rectangle is queried using + V4L2_SEL_TGT_COMPOSE_DEFAULT . It is usually equal to the +bounding rectangle. + +The part of a buffer that is modified by the hardware is given by + V4L2_SEL_TGT_COMPOSE_PADDED . It contains all pixels +defined using V4L2_SEL_TGT_COMPOSE_ACTIVE plus all +padding data modified by hardware during insertion process. All pixels outside +this rectangle must not be changed by the hardware. The +content of pixels that lie inside the padded area but outside active area is +undefined. The application can use the padded and active rectangles to detect +where the rubbish pixels are located and remove them if needed. + +
+ +
+ + Configuration of video output + +For output devices targets and ioctls are used similarly to the video +capture case. The composing rectangle refers to the +insertion of an image into a video signal. The cropping rectangles refer to a +memory buffer. It is recommended to configure the composing targets before to +the cropping targets. + +The cropping targets refer to the memory buffer that contains an image to +be inserted into a video signal or graphical screen. The limits of cropping +coordinates are obtained using V4L2_SEL_TGT_CROP_BOUNDS . +All coordinates are expressed in natural units for a given format. Pixels are +highly recommended. The top/left corner is always point (0,0) +. The width and height is equal to the image size specified using + VIDIOC_S_FMT ioctl. + +The top left corner, width and height of the source rectangle, that is +the area from which image date are processed by the hardware, is given by the + V4L2_SEL_TGT_CROP_ACTIVE . Its coordinates are expressed +in in the same coordinate system as the bounds rectangle. The active cropping +area must lie completely inside the crop boundaries and the driver may further +adjust the requested size and/or position according to hardware +limitations. + +For output devices the default cropping rectangle is queried using + V4L2_SEL_TGT_CROP_DEFAULT . It is usually equal to the +bounding rectangle. + +The part of a video signal or graphics display where the image is +inserted by the hardware is controlled by V4L2_SEL_TGT_COMPOSE_ACTIVE + target. The rectangle's coordinates are expressed in driver +dependant units. The only exception are digital outputs where the units are +pixels. For other types of devices, the coordinate system guarantees that if +sizes of the active cropping and the active composing rectangles are equal then +no scaling is performed. The composing rectangle must lie completely inside +the bounds rectangle. The driver must adjust the area to fit to the bounding +limits. Moreover, the driver can perform other adjustments according to +hardware limitations. + +The device has a default composing rectangle, given by the +V4L2_SEL_TGT_COMPOSE_DEFAULT target. This rectangle shall cover what +the driver writer considers the complete picture. It is recommended for the +driver developers to put the top/left corner at position (0,0) +. Drivers shall set the active composing rectangle to the default +one when the driver is first loaded. + +The devices may introduce additional content to video signal other than +an image from memory buffers. It includes borders around an image. However, +such a padded area is driver-dependent feature not covered by this document. +Driver developers are encouraged to keep padded rectangle equal to active one. +The padded target is accessed by the V4L2_SEL_TGT_COMPOSE_PADDED + identifier. It must contain all pixels from the +V4L2_SEL_TGT_COMPOSE_ACTIVE target. + +
+ +
+ + Scaling control. + +An application can detect if scaling is performed by comparing the width +and the height of rectangles obtained using V4L2_SEL_TGT_CROP_ACTIVE + and V4L2_SEL_TGT_COMPOSE_ACTIVE targets. If +these are not equal then the scaling is applied. The application can compute +the scaling ratios using these values. + +
+ +
+ +
+ + Comparison with old cropping API. + +The selection API was introduced to cope with deficiencies of previous + API , that was designed to control simple capture +devices. Later the cropping API was adopted by video output drivers. The ioctls +are used to select a part of the display were the video signal is inserted. It +should be considered as an API abuse because the described operation is +actually the composing. The selection API makes a clear distinction between +composing and cropping operations by setting the appropriate targets. The V4L2 +API lacks any support for composing to and cropping from an image inside a +memory buffer. The application could configure a capture device to fill only a +part of an image by abusing V4L2 API. Cropping a smaller image from a larger +one is achieved by setting the field +&v4l2-pix-format;::bytesperline . Introducing an image offsets +could be done by modifying field &v4l2-buffer;::m:userptr + before calling VIDIOC_QBUF . Those +operations should be avoided because they are not portable (endianness), and do +not work for macroblock and Bayer formats and mmap buffers. The selection API +deals with configuration of buffer cropping/composing in a clear, intuitive and +portable way. Next, with the selection API the concepts of the padded target +and constraints flags are introduced. Finally, &v4l2-crop; + and &v4l2-cropcap; have no reserved +fields. Therefore there is no way to extend their functionality. The new + &v4l2-selection; provides a lot of place for future +extensions. Driver developers are encouraged to implement only selection API. +The former cropping API would be simulated using the new one. + +
