Definition of a port. A port is the entity that is exposed by components to receive or transmit buffer headers (MMAL_BUFFER_HEADER_T). A port is defined by its MMAL_ES_FORMAT_T.
It may be possible to override the buffer requirements of a port by using the MMAL_PARAMETER_BUFFER_REQUIREMENTS parameter.
| uint32_t MMAL_PORT_T::buffer_alignment_min |
Minimum alignment requirement for the buffers (Read Only). A value of zero means no special alignment requirements. This is set by the component.
| uint32_t MMAL_PORT_T::buffer_num |
Actual number of buffers the port will use. This is set by the client.
| uint32_t MMAL_PORT_T::buffer_num_min |
Minimum number of buffers the port requires (Read Only). This is set by the component.
| uint32_t MMAL_PORT_T::buffer_num_recommended |
Number of buffers the port recommends for optimal performance (Read Only). A value of zero means no special recommendation. This is set by the component.
| uint32_t MMAL_PORT_T::buffer_size |
Actual maximum size of the buffers that will be sent to the port. This is set by the client.
| uint32_t MMAL_PORT_T::buffer_size_min |
Minimum size of buffers the port requires (Read Only). This is set by the component.
| uint32_t MMAL_PORT_T::buffer_size_recommended |
Size of buffers the port recommends for optimal performance (Read Only). A value of zero means no special recommendation. This is set by the component.
| uint32_t MMAL_PORT_T::capabilities |
Flags describing the capabilities of a port (Read Only). Bitwise combination of Port capabilities values.
Component this port belongs to (Read Only)
Format of the elementary stream
| uint16_t MMAL_PORT_T::index |
Index of the port in its type list (Read Only)
| uint16_t MMAL_PORT_T::index_all |
Index of the port in the list of all ports (Read Only)
| uint32_t MMAL_PORT_T::is_enabled |
Indicates whether the port is enabled or not (Read Only)
| const char* MMAL_PORT_T::name |
Port name. Used for debugging purposes (Read Only)
| struct MMAL_PORT_PRIVATE_T* MMAL_PORT_T::priv |
Private member used by the framework
Type of the port (Read Only)
| struct MMAL_PORT_USERDATA_T* MMAL_PORT_T::userdata |
Field reserved for use by the client
