* which will have one or many adapt processes that are provided by the input object
|
|
* and are responsible for converting the frame data to the format required for
|
|
* the selected video encoder.

* This video source should be contained within a FVideoSourceGroup which is responsible
|

* for telling each source to push a frame to EpicRtc at the expected rate. This source
|
|
* will make sure that the adapter has valid output and if so will create a frame
|
|
* for EpicRtc. Otherwise it will continue to wait until the next frame.
