# Raspberry Pi (VC4 and PiSP) specific vendor controls
vendor: rpi
controls:
- StatsOutputEnable:
type: bool
description: |
Toggles the Raspberry Pi IPA to output the hardware generated statistics.
When this control is set to true, the IPA outputs a binary dump of the
hardware generated statistics through the Request metadata in the
Bcm2835StatsOutput control.
\sa Bcm2835StatsOutput
- Bcm2835StatsOutput:
type: uint8_t
size: [n]
description: |
Span of the BCM2835 ISP generated statistics for the current frame.
This is sent in the Request metadata if the StatsOutputEnable is set to
true. The statistics struct definition can be found in
include/linux/bcm2835-isp.h.
\sa StatsOutputEnable
- ScalerCrops:
type: Rectangle
size: [n]
description: |
An array of rectangles, where each singular value has identical
functionality to the ScalerCrop control. This control allows the
Raspberry Pi pipeline handler to control individual scaler crops per
output stream.
The order of rectangles passed into the control must match the order of
streams configured by the application. The pipeline handler will only
configure crop retangles up-to the number of output streams configured.
All subsequent rectangles passed into this control are ignored by the
pipeline handler.
If both rpi::ScalerCrops and ScalerCrop controls are present in a
ControlList, the latter is discarded, and crops are obtained from this
control.
Note that using different crop rectangles for each output stream with
this control is only applicable on the Pi5/PiSP platform. This control
should also be considered temporary/draft and will be replaced with
official libcamera API support for per-stream controls in the future.
