New constructs a new SampleBuilder.

WithMaxTimeDelay ensures that packets that are too old in the buffer get purged based on time rather than building up an extraordinarily long delay.

WithPacketHeadHandler set a head packet handler to allow inspecting the packet to extract certain information and return as custom metadata.

WithPacketReleaseHandler set a callback when the builder is about to release some packet.

WithPartitionHeadChecker is obsolete, it does nothing.

SampleBuilder buffers packets until media frames are complete.

An Option configures a SampleBuilder.
