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 convert between a C struct and the RBSP representation of the SPS and PPS nal units. The allegro driver writes the nal units into the v4l2 capture buffer in front of the actual video data which is written at an offset by the IP core. The remaining gap is filled with a filler nal unit.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
