Note that an output or mem2mem device is not implemented yet, so this sink pad currently has no links. For more info, refer to the latest versions of the i. The IRT carries out 90 and degree image rotation operations. The CSI supports cropping the incoming raw sensor frames. The VDIC subdev supports motion compensated de-interlacing, with three motion compensation modes:

The VDIC also contains a Combiner that combines two image planes, with alpha blending and color keying. This is the IC pre-processing encode entity.
The deinterlaced output frames from the VDIC cxi be sent to the IC pre-process viewfinder task for further conversions. When this happens, the IPU triggers csu mechanism to re-establish vertical sync by adding 1 dummy line every frame, which causes a rolling effect from image to image, and can last a long time before a stable image is recovered. Note that an output or mem2mem device is not implemented yet, so this sink pad currently has no links.
This can be used to discard really high interval errors that might be due to interrupt latency from high system load.

Guidelines for Video4Linux pixel format 4CCs 2. This can reduce noise caused by interrupt latency. The lnux driver They have two or more sink pads to select from either camera sensors with a parallel interface, or from MIPI CSI-2 virtual channels from imx6-mipi-csi2 entity.
This pipeline routes frames from the CSI direct pad to the VDIC entity to support motion-compensated de-interlacing high motion mode onlyscaling up to x, CSC, flip, and rotation:. To aid in configuration and for backward compatibility with V4L2 applications that access controls only from video device nodes, the capture device interfaces inherit controls from the active entities in the current pipeline, so controls can be accessed either directly from the subdev or from the active capture mippi interface.
The IRT carries out 90 and degree image rotation operations.

The CSI supports cropping the incoming raw sensor frames. Setup links media-ctl -l “‘adv ‘: The VDIC carries out motion compensated de-interlacing, with three motion compensation modes: The VDIC subdev supports motion compensated ,ipi, with three motion compensation modes: Scaling, color-space conversion, horizontal and vertical kinux, and image rotation via IC task subdevs.
The CSI also supports fixed divide-by-two downscaling indepently in width and height. If one of these controls is changed during streaming, the FIM will be reset and will continue at the new settings.

If any intervals are higher than this value, those samples are discarded and do not enter into the average. MX6 Quad, there are two video mux entities. Concurrent independent streams, by configuring pipelines to multiple video capture interfaces using independent entities.
Input capture requires hardware support. The Virtual Video Test Driver vivid These controls will configure an input capture channel as the method for measuring frame intervals. This is a Synopsys DesignWare core. This is the IC pre-processing entity.

For more info, refer to the latest versions of the i. Using without lircd 5. Multiple source pads can mip enabled to independently stream from multiple virtual channels. The bttv driver 8. This pipeline uses the preprocess encode entity to route frames directly from the CSI to the IC, to carry out scaling up to x resolution, CSC, flipping, and image rotation:.
With this link the VDIC can only operate in high motion mode. With this pipeline, it can also operate in low and medium modes, fsi these modes require receiving frames from memory buffers.
