Data Fields
rmff_object_t	obj
uint16_t	id
	The track number. It is unique regarding the file.
uint32_t	max_bit_rate
	The maximum bitrate in bits/second.

uint32_t	duration
char *	name
	The track's name.
char *	mime_type
	The track's MIME type.
uint32_t	type_specific_size
	The size of the track specific data in bytes.
unsigned char *	type_specific_data
	Track type specific data.

Detailed Description

The MDPR track headers.

Each track in a RealMedia file contains the MDPR header. The values are stored in big endian byte order. The application should use the functions rmff_get_uint16_be, rmff_get_uint32_be, rmff_put_uint16_be and rmff_put_uint32_be for accessing the members.

Field Documentation

uint32_t rmff_mdpr_t::avg_packet_size

The average packet size in bytes. When creating a file this value will be updated automatically by the library.

uint32_t rmff_mdpr_t::max_bit_rate

The maximum bitrate in bits/second. When creating a file this value will be updated automatically by the library.

uint32_t rmff_mdpr_t::max_packet_size

The maximum packet size in bytes. When creating a file this value will be updated automatically by the library.

char* rmff_mdpr_t::mime_type

The track's MIME type. Use the rmff_set_track_data function for setting it.

char* rmff_mdpr_t::name

The track's name. Use the rmff_set_track_data function for setting it.

unsigned char* rmff_mdpr_t::type_specific_data

Track type specific data. Use the rmff_set_type_specific_data function for setting it. It usually contains a ::real_video_props_t or ::real_audio_v4_props_t structure.
