Detailed Description

Private message definitions, defining the message API between the host and VideoCore.

Macro Definition Documentation

#define MMAL_FORMAT_EXTRADATA_MAX_SIZE 128

Maximum size of the format extradata. FIXME: should probably be made bigger and maybe be passed separately from the info.

#define MMAL_MAX_PORTS 8

Max ports per component

#define MMAL_VC_CORE_STATS_NAME_MAX 32

Length of the name in the core stats message

#define MMAL_VC_SHORT_DATA 128

Size of space reserved in a buffer message for short messages.

#define MMAL_WORKER_EVENT_SPACE 256

Maximum number of event data bytes that can be passed in the message. More than this and the data is passed in a bulk message.

#define MMAL_WORKER_MSG_LEN 28

A MMAL_CONTROL_SERVICE_T gets space for a single message. This is the space allocated for these messages.

Typedef Documentation

typedef struct mmal_worker_buffer_from_host mmal_worker_buffer_from_host

Receive a buffer from the host.

See also: mmal_port_send_buffer()

typedef struct mmal_worker_event_to_host mmal_worker_event_to_host

Send an event buffer from the host.

See also: mmal_port_send_event()

Enumeration Type Documentation

enum MMAL_WORKER_CMD_T

Message ids sent to worker thread.

enum MMAL_WORKER_PORT_ACTIONS

List of actions for a port

Enumerator
MMAL_WORKER_PORT_ACTION_UNKNOWN	Unkown action
MMAL_WORKER_PORT_ACTION_ENABLE	Enable a port
MMAL_WORKER_PORT_ACTION_DISABLE	Disable a port
MMAL_WORKER_PORT_ACTION_FLUSH	Flush a port
MMAL_WORKER_PORT_ACTION_CONNECT	Connect 2 ports together
MMAL_WORKER_PORT_ACTION_DISCONNECT	Disconnect 2 ports connected together
MMAL_WORKER_PORT_ACTION_SET_REQUIREMENTS	Set buffer requirements
MMAL_WORKER_PORT_ACTION_MAX	Make the enum 32bits
