Detailed Description

MediaPin represents an elementary media stream.

MediaPin object can exist for audio, video or any other type of stream. However, AVBlocks can process only the audio and video streams.

MediaPin objects are used as inputs and outputs of Transcoder.

Property Documentation

int Connection

getset

Connection ID.

This should not be confused with the stream ID that is defined for certain stream types.

A Transcoder object matches and connects input and output pins by their connection ID. The Transcoder processes the connected pins and ignores the unconnected pins.

Pins are connected to one another according to the following rules:

• Input pins with connection ID greater than PinConnection.Auto are connected to output pins with the same connection ID. In this case the Transcoder requires that a single unique connection ID is used by exactly one input and one output pin.
• Input and output pins with connection ID equal to PinConnection.Auto are connected automatically based on their media type (audio or video).
• Input and output pins with connection ID equal to PinConnection.Disabled are ignored.

IDictionary<string,object> Params

getset

A collection of pin parameters.

These parameters affect the processing of the elementary stream represented by this pin. The default value of this property is an empty list. A System.Collections.Generic.Dictionary instance can be used to set the parameters.

StreamInfo StreamInfo

getset

Information about the elementary stream represented by this pin.

The Transcoder ignores pins that are not audio or video elementary streams. If the value of StreamInfo.MediaType is MediaType.Audio, it is safe to cast this property to AudioStreamInfo. If the media type is MediaType.Video, it is safe to cast this property to VideoStreamInfo.
