Ingestion
Ingestion brings media into Media Server so that it can be processed. For example, if you ingest video then Media Server must extract the video and audio from the container and decode the streams so that they can be analyzed and transcoded.
Your configuration must include exactly one ingest task. For example:
[Session] Engine0=Ingest [Ingest] Type=Video
This example has a task named Ingest. The engine used to complete the task is specified by the Type parameter, in this case the Video ingest engine. Notice that no source file or stream is specified in the configuration. You provide the path of a file or the URL of a stream to Media Server in the Process action when you start processing.
Ingest engines produce one or more image tracks and possibly audio tracks:
- Each image track is named
taskName.Image_n, wheretaskNameis the name of the task andnis a unique number. Tracks are numbered from 1. - Each audio track is named
taskName.Audio_lang_n, wheretaskNameis the name of the task,langis the language, andnis a unique number. If the language is unknown, each track is namedAudio__n(note the double underscore), wherenis a unique number. The tracks are numbered from 1.
For example, if you ingest video from a TV broadcast, Media Server might produce an image track named taskName.Image_1, and three audio tracks: taskName.Audio_French_1, taskName.Audio_English_2, and taskName.Audio_German_3.
When you configure Media Server, the first image track produced by the ingest task can be specified by the alias Default_Image. The first audio track produced by an ingest engine can be specified by the alias Default_Audio.
