        The file type hint is a constant defined in AVMediaFormat.h whose value is a UTI for a file format. e.g. AVFileTypeAIFF. Sometimes the type of a file cannot be determined from the data, or it is actually corrupt. The file type hint tells the parser what kind of data to look for so that files which are not self identifying or possibly even corrupt can be successfully parsed.

        public long numberOfLoops()
        "numberOfLoops" is the number of times that the sound will return to the beginning upon reaching the end. A value of zero means to play the sound just once. A value of one will result in playing the sound twice, and so on.. Any negative number will loop indefinitely until stopped.

      • play

        public boolean play()

      • playAtTime

        public boolean playAtTime​(double time)
        This method starts the audio hardware synchronously (if not already running), and triggers the sound playback which is streamed asynchronously at the specified time in the future. Time is an absolute time based on and greater than deviceCurrentTime.

      • setNumberOfLoops

        public void setNumberOfLoops​(long value)
        "numberOfLoops" is the number of times that the sound will return to the beginning upon reaching the end. A value of zero means to play the sound just once. A value of one will result in playing the sound twice, and so on.. Any negative number will loop indefinitely until stopped.

      • setRate

        public void setRate​(float value)
        See enableRate. The playback rate for the sound. 1.0 is normal, 0.5 is half speed, 2.0 is double speed.
