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:
