Code:
Describes the type of presentation (if it is audio only or
audio and video). This setting allows different audio streams, one
that uses a higher bit rate for audio-only presentations and one that
uses a lower bit rate for audio-video presentations, to be assigned
in an audience. The setting is used at runtime to determine what
audio codec to use.
Default:
audio-video
Values:
audio-video, audio-only
Type:
string
Example:
<presentationType type="string">audio-video</presentationType>
I don't uderstand the codec selection thing they talk about. What if I use audio-video and I encode only audio? What if I encode video only and no audio?
