Changing settings in frame chunks vs. separate chunks

[steveanton]

As of #14 the mechanism for changing encoder settings is to bundle a dictionary with the input frame. An alternative discussed was to have a separate chunk type that only has changed settings (no input frame).

[steveanton]

Pros/cons I could come up with:

Bundling setting changes with inputs:

Pros:

• Obvious how it works with backpressure.

Cons:

• Prevents settings from being changed early which could impact performance if the setting change requires some time.

Separate setting change chunks:

Pros:

• Allows settings to be changed early without new input.

Cons:

• Backpressure on setting change chunks doesn't really make sense.

I think this is should be addressed in the bigger issue at #35

[steveanton]

I think these are two different issues. #20 here refers to dynamic settings which I believe do not have any objections to being in band. #35 refers to static settings which require a re-initialization. I would not be surprised if we support dynamic vs. static setting changes differently.
