MediaPin¶

The MediaPin class represents an elementary media stream.

MediaPin objects can exist for audio, video, or any other type of stream. However, AVBlocks can process only audio and video streams. MediaPin objects are used as inputs and outputs of the Transcoder.

Class¶

class avblocks.MediaPin¶

Bases: IImmutable

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.

clone() → MediaPin¶

Creates a deep copy of this object.

Returns:: A new MediaPin object

property connection: int¶

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.

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.

property immutable: bool¶

Returns whether the object is immutable. An immutable object cannot be modified and all modifying methods fail to produce a result.

An immutable object can be modified by the AVBlocks library. Object immutability spreads to all nested objects. Therefore it is not possible to add/set an immutable object to a mutable object. When cloned an immutable object becomes mutable.

property params: ParameterList¶

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 ParameterList.

property stream_info: StreamInfo | None¶

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.media_type 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.
