Hello linux-media.
I use cx231xx driver with my August Vgb100 USB video grabber. It works
great. It automatically detects my device and I can watch the video
from analog camera on my Raspberry Pi, and I am very happy about how
it works.
But there is a catch. I want to connect 3 such cameras to my
To improve image quality, entities involved within the image partition

requirements and to take consideration of the number of taps in their
filters.

Provide a helper to describe when the partition algorithm is in use on a
given pipeline. This improves readability to the purpose of the code,
rather than obtusely checking the number of partitions.

The UDS and SRU (and SHP) require expanded partition windows to support
overlapping partition windows as a means of discarding discontinous pixel data,

The 'mp' value is used through several calculations in determining the

The image partition algorithm operates on the image dimensions as input

This is v6 of the Allegro DVT H.264 encoder driver found in the EV
family of the Xilinx ZynqMP platform.
Only minor changes this time. I dropped the implementation of the
selection api, removed all references mentioning the decoder, and fixed
a few issues reported by sparse and smatch.

The allegro hardware encoder does not write SPS/PPS nal units into the
encoded video stream. Therefore, we need to write the units in software.
The implementation follows Rec. ITU-T H.264 (04/2017) to allow to
