static int32_t | memsrc_src_pad_process (StreamPad *pad) |
| Function is the loop function of the memsrc source pad which runs in the task thread. It reads the chunk_size of data from the memory and pushes it to peer element sink pad. When EOF memory is reached, the task goes to PAUSE state.
|
|
static int32_t | memsrc_change_state (StreamElement *element, PipelineState state) |
| Function handles the state change of the element in a pipeline.
|
|
static uint8_t | memsrc_handle_src_event (StreamPad *pad, StreamEvent *event) |
| Function handles the events of the element source pad.
|
|
static uint8_t | memsrc_handle_src_query (StreamPad *pad, StreamQuery *query) |
| Function Description: This function is the empty impl of the src pad query handler.
|
|
static uint8_t | memsrc_src_activate_push (StreamPad *pad, uint8_t active) |
| Function activates or deactivates the memsrc source pad in PUSH mode.
|
|
static uint8_t | memsrc_src_activate_pull (StreamPad *pad, uint8_t active) |
| Function activates or deactivates the memsrc source pad in PULL mode.
|
|
static uint8_t | memsrc_src_activate (StreamPad *pad, uint8_t active) |
| queue src pad activatation handler. Activation is handled by the peer sink pad, this should just handle the deactivation.
|
|
static FlowReturn | memsrc_pull (StreamPad *pad, StreamBuffer *buffer, uint32_t size, uint32_t offset) |
| Function is the pull function of the memsrc source pad in SCHEDULING_PULL mode. It reads the size of data from the offset to buffer.
|
|
static int32_t | memsrc_get_property (StreamElement *element_ptr, uint16_t prop, uint32_t *val_ptr) |
| This function get memory source element properties.
|
|
static int32_t | memsrc_set_property (StreamElement *element_ptr, uint16_t prop, uintptr_t val) |
| This function set memory source element properties.
|
|
int32_t | memsrc_init (StreamElement *element) |
| this function initializes the memory source element and source pad. all the pad's handlers are intialized.
|
|
int32_t | memsrc_set_buffer (ElementHandle element, int8_t *location, uint32_t size) |
| This function sets a destiniaiton buffer to be read by memory source element.
|
|
int32_t | memsrc_set_push_chunk_size (ElementHandle element, uint32_t chunk_size) |
| This function sets the chunk size in which the momery source sends the data in push mode.
|
|
int32_t | memsrc_get_push_chunk_size (ElementHandle element, uint32_t *chunk_size) |
| This function gets the chunk size.
|
|
static FlowReturn | memsrc_read (ElementMemSrc *memsrc, int32_t offset, int32_t length, StreamBuffer *buf) |
| Reads the data from the memory array specified by the element. NOTE: Function may or may not be able to read the required length of data. Returns FLOW_OK or FLOW_EOS when EOF file is encountered.
