Detailed Description

MPEG sample auxiliary information functions.

Function Documentation

◆ MP4AddSampleAuxiliaryInformation()

MP4Err MP4AddSampleAuxiliaryInformation	(	MP4Media	theMedia,
		u8	isUsingAuxInfoPropertiesFlag,
		u32	aux_info_type,
		u32	aux_info_type_parameter,
		MP4Handle	dataH,
		u32	sampleCount,
		MP4Handle	sizesH
	)

Add sample auxiliary information data for a range of samples.

The first three parameters are used to identify the type of sample auxiliary information.

Note: before adding data, MP4SetupSampleAuxiliaryInformation() has to be called with the same parameters.

◆ MP4GetSampleAuxiliaryInformation()

MP4Err MP4GetSampleAuxiliaryInformation	(	MP4Media	theMedia,
		u32 *	outCount,
		MP4Handle	isUsingAuxInfoPropertiesFlags,
		MP4Handle	aux_info_types,
		MP4Handle	aux_info_type_parameters
	)

Get information about all sample auxiliary information for a track.

The MP4Handles will contain an array of u8 and u32, which will represent the description of each instance of sample auxiliary information inside a track.

Parameters

outCount	the number of different sample auxiliary information.
isUsingAuxInfoPropertiesFlags
aux_info_types
aux_info_type_parameters

◆ MP4SetupSampleAuxiliaryInformation()

MP4Err MP4SetupSampleAuxiliaryInformation	(	MP4Media	theMedia,
		u8	isUsingAuxInfoPropertiesFlag,
		u32	aux_info_type,
		u32	aux_info_type_parameter,
		u8	default_sample_info_size
	)

Setup and initialize sample auxiliary information for a track.

It must be called before adding sample auxiliary data. It can be called multiple times with different type, parameter combinations to setup multiple sample auxiliary information for a single track. To add sample auxiliary data for a sample use MP4AddSampleAuxiliaryInformation()
