interface IMediaSample

Extends com.amazon.apmf.IStandard MediaSample holds the audio/video encoded bitstream data and all the related meta data. MediaSample contains the following information:

• Presentation timestamp, the time at which the MediaSample needs to be displayed/rendered.
• Duration, the duration of the MediaSample
• Decoding timeStamp, the time at which the MediaSample needs to be decoded.
• Sync/Non-Sync frame, indicates if the MediaSample is key frame or not.
• Encryption info, contains the encryption related information for encrypted MediaSample.
