SDK / exoplayer

[Problem]
CC1 is shown even when CC2-3-4 is selected

[Solution]
 * use incoming channel and frame information
 * Misc Codes need to handle use Frame information
 * Add checks everywhere

[Test]
* Live channels and already existing test should not show any difference
in behavior when CC1 is selected.
* Live channels might have CC2-CC3-CC4
* Sarnoff test content has specific test cases for channel support
