bool True if the operation succeeded. False otherwise.
Appends sample frames to the specified audio track.
Keep the number of video frames and audio samples aligned so that each track is syncrhonized as much as possible. For instance, a file with 30FPS video and 48KHz video, each addition of one video frame should be followed by the addition of a buffer of 1600 sample frames.
