This API lets you add additional audio track to the video file. While playing the video user can switch between these tracks.
The files can be of different formats or use different codecs - the result file format depend on the extension of the result file. You can set encoding of the result file to any supported codec or you can leave it default.
The user can also set different time options for the audio track such as starting position, ending position and offset. These options determine at what time point of the video the new audio will start playing and when it will stop.
