Here a NPE can happen when you have alternative renderers in the factory, ie. having a FfmpegRenderer. In this case, when it's not selected by any track rendererConfigurations array will have a null entry in it.

Expected result

A null check should be added to avoid NPE.

Actual result

A NPE is thrown when invoking this method with FfmpegRenderer present.

Media

None
