This is an MP4 Parser which extracts CEA-708 packets from Fragmented MP4 streams.
The Closed Caption Parser (shaka.media.ClosedCaptionParser) will own this MP4 Parser, and will initialize it and call it as shown. As data comes in, the parser will parse this data, and the caption packets data then be returned in a callback (on708Data), as shown. Here, a theoretical decoder (future pull request, mentioned as a Todo comment) will decode and extract the parsed captions from these packets.
Issue #2648
This fixes all the license headers in the main library, which corrects
the appearance of the main license in the compiled output.
It seems that the `!` in the header forces the compiler to keep it in
the output. I believe older compiler releases did this purely based
on `@license`.

This reflects changes in Google's policy on JavaScript license
headers, which should be smaller to avoid increasing the size of the
binary unnecessarily.
This also updates the company name from "Google, Inc" to "Google LLC".

Using "new Uint8Array" with a TypedArray creates a copy of the buffer;
this is unnecessarily expensive for large buffers. This adds a rule
to disallow using it in favor of a new utility that correctly creates
a new "view" on the same buffer.
Note it is fine to pass an ArrayBuffer to "new Uint8Array" and it won't
copy; but there there are many cases where the type is BufferSource,
so it could be a TypedArray. Unfortunately, there are many other cases
where we explicitly pass an ArrayBuffer; but the compiler rules don't
allow us to whitelist this case (since ArrayBuffer is part of
BufferSource).

This changes the network API to use BufferSource instead of ArrayBuffer,
which allows plugins to return a "view" on a buffer instead of the
whole buffer. This also adds some utilities for changing between
views and buffers.
Lastly this forbids the use of the "buffer" property of TypedArrays
since it doesn't work with partial "views". This audits and fixes the
usages of the "buffer" property to ensure correct usage.
It should be noted that both MSE and EME accept a BufferSource as input,
so we don't need to convert a "view" into an ArrayBuffer before passing
to it.

This is a fully automated change. The linter will fail because the
extra indentation caused line-length errors. These won't be fixed
automatically. They are fixed in a follow-up to make this one fully
automated.

- Disallow mixing different types of some operators (e.g. && ||).
- Disallow useless constructors.
- Require a newline between class members.
- Require spacing around arrow functions.
- Require using the compound assignment when possible (e.g. +=).
- Check for possible errors in assignments involving "await".

To make it clearer that the CloseCaptionParser uses MuxJS (and therefore
it requires MuxJS) it has been renamed to be MuxJSClosedCaptionParser. To
further isolate the dependency on MuxJS, the support check that we must do
before using the Caption Parser has been moved to a static function on the
parser.

Similar to Transmuxer, adding a Caption Parser class as a wrapper of
mux.js's Caption Parser, and move all relevant operations from Media
Source Engine to Caption Parser wrapper class.
