Source ContentΒΆ
We'll be packaging the original content for playback and delivery. The source content consists of a combination audio tracks and video tracks. The video is available in different bitrates (for adaptive streaming) and the audio has been encoded using a variety of audio codecs to support the best quality audio for the different devices.
The following is a list of all the files that we use as input for the packaging. Source content:

| audio_he-aac.mp4 | HE-AAC (High Efficiency AAC) audio track |
| audio_dts-express.mp4 | DTS Express 5.1 audio track |
| audio_ac3.mp4 | AC-3 (Dolby Digital) audio track |
