As we know, The framebased format can be used to support a lot of formats other than YUV and MJPEG, for example: H264 or H265. And Nowadays, the H264 and H265 is used more and more compared to the MJPEG, so there is a need to support such usecase, although the new UVC 1.5 and the UVC1.1 extensions already support H264, but they are much more expensive and most of the time, what we need is just a channel to stream the video frames. In this patch, we implement the framebased format and set it to H264 by default, and the users could change the video format as they need through the guid configfs attribute node.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
