Video Ingest Engine

The video ingest engine ingests video and audio files and streams, producing image and audio tracks that can be processed by other engines. The engine automatically detects the properties of the source, but you can override the detected properties by setting parameters in the task configuration section.

Configuration Parameter Description
Channels The number of audio channels in the source.
Decode A Boolean value that specifies whether Media Server decodes the ingested video.
DeinterlaceType Specifies whether to deinterlace the video.
EnabledStreamTypes A comma-separated list of the types of data that you want to ingest, for example video and audio.
EnableGPU Specifies whether to use a graphics card for decoding, instead of the CPU.
Format The format of the video source.
FrameRate The frame rate of the video source.
GPUDeviceID The device ID of the graphics card to use for decoding video.
IngestDateTime The ingest start time that is used to produce record timestamps.
MaximumDuration The maximum amount of video and audio to ingest, before stopping ingestion.
MaxNumParallel The maximum number of threads to use for decoding the source media.
OpenSourceTimeout The maximum amount of time that Media Server should continue attempting to read a file or stream.
PixelFormat The pixel format of the video source.
RTSPTransport The transport protocol to use when the source is an RTSP stream.
SampleRate The sample rate of the audio source.
StartOffset The position in a video file at which to start processing.
StreamTimeout The maximum amount of time to wait for a stream to produce a record, before stopping ingestion.
Type The type of ingest engine to use. Set this parameter to Video.
VideoSize The display size of the video source.

The video ingest engine produces a proxy track, named taskName.Proxy, where taskName is the name of the ingest task.

Additionally, depending on the source, the engine produces the following tracks:

  • Image tracks named taskName.Image_n, where n is a unique number starting from 1.
  • Image tracks named taskName.Closed_Caption_lang_n, where lang is the language and n is a unique number starting from 1. These tracks contain the subtitle (closed caption) images.
  • Audio tracks named taskName.Audio_lang_n, where lang is the language and n is a unique number starting from 1. If the language is unknown, each track is named Audio__n, where n is a unique number (note the double underscore).
  • KLV tracks, named taskName.KLV_n, where n is a unique number starting from 1.

The first image track can be referred to using the aliases Default_Image and Image_1. The first audio track can be referred to using the alias Default_Audio. The first closed caption track can be referred to using the alias Default_Closed_Caption.
