This attribute contains the sequence header. The default value is 1:1.Īfter the output type is set, the video encoder updates the type by adding the MF_MT_MPEG_SEQUENCE_HEADER attribute. For more information about profile and level constraints, refer to Annex A of ITU-T H.264.

The encoder can derive the proper level for a given video stream, taking into account the format constraints and the characteristics of the video. It is recommended not to set the level in the media type, and allow the encoder to select the level. The default value is –1, indicating that the encoder will select the encoding level.
