ExoPlayer extension function that calculates the DK (Dropped to Keyframe Count), that represents the number of times all buffers to a keyframe were dropped. Each time buffers to a keyframe are dropped, this counter is increased by one, and the dropped buffer counters are increased by one (for the current output buffer) plus the number of buffers dropped from the source to advance to the keyframe.

ExoPlayer extension function that calculates the metric to evaluate the rendering performance called Video Frame Processing Offset (VFPO). VFPO measures how early the player processes a video frame compared to its presentation time, in microseconds.
