Mpeg4SampleDescription

Valid for: CANoe DE • CANoe4SW DE

Property

Contains the sample description box for an MP4 or 3GP file.

byte[]

The sample description box describes the encoding used for a stream in the file.
The MPEG-4 file source sets this attribute on the media type for each stream. The value of the property is the raw data in the sample description box. If the MPEG-4 file source can parse the sample description, it also adds the format details to the media type. Otherwise, the application or the decoder must parse the sample description from the Mpeg4SampleDescription property.
When setting this property on a sink writer accessing a MPEG-4 sink through the MediaSetMediaType function, the data for the property Mpeg4SampleDescription should not change after one or more samples have been sent to the sink writer via the MediaWrite function.
