addSink

open fun addSink(sink: VideoSink)

Adds a VideoSink to the track. A track can have any number of VideoSinks. VideoSinks will replace renderers. However, converting old style texture frames will involve costly conversion to I420 so it is not recommended to upgrade before all your sources produce VideoFrames.
