Previously, if renderFramesAutomatically = false, DefaultVideoFrameProcessor
may call onInputStreamProcessedListener after all frames have been
onOutputFrameAvailableForRendering, but before they had all been rendered and
freed.
Delay onInputStreamProcessedListener being called and subsequent DVFP
reconfiguration of effects, until all frames are rendered.
Tested using exoplayer setVideoEffects demo with playlist
