|
void | FILE_Dump_Task (void *param) |
| this function is a task that writes data to the SD card
|
|
static uint8_t | filesink_sink_pad_activation_handler (StreamPad *pad, uint8_t active) |
| This function activates the sink pad and allocates memory for the file sink element.
|
|
static FlowReturn | filesink_sink_pad_chain_handler (StreamPad *pad, StreamBuffer *buf) |
| This pad function accumulates data from the decoder and pushes it onto the selected audio driver. The audio sink maintains a double buffer and starts sending data once both the buffers are full. It blocks if the previous data is not sent out by the driver for some reason.
|
|
static int32_t | filesink_sink_pad_process_handler (StreamPad *pad) |
| File sink pad process handler.
|
|
static uint8_t | filesink_sink_pad_event_handler (StreamPad *pad, StreamEvent *event) |
| This function is the calls the specified audio device driver implementation of the sink pad event handler.
|
|
static int32_t | filesink_change_state (StreamElement *element, PipelineState new_state) |
| This function changes the file sink state and calls the appropriate apis for that state and takes the actions and then returns. PipelineState Transition: NULL to READY: Open file READY to PAUSE: Activate sink pads and their peer pads PAUSE to PLAY: Start Writing PAUSE to READY: Deactivate sink pads and their peer pads READY to NULL: Close file.
|
|
static uint8_t | filesink_sink_pad_query_handler (StreamPad *pad, StreamQuery *query) |
| This pad function handles query from the pipeline. If not able to handle the query then it pushes the query to its peer.
|
|
static int32_t | filesink_set_property (StreamElement *element_ptr, uint16_t prop, uint32_t val) |
| This function sets audio sink element's properties.
|
|
static int32_t | filesink_get_property (StreamElement *element_ptr, uint16_t prop, uint32_t *val_ptr) |
| This function gets audio sink element's properties.
|
|
int32_t | filesink_init_element (StreamElement *element) |
| this function initializes the audio sink element and sink pads
|
|
int32_t | filesink_set_location (ElementHandle element, char *path) |
| This function sets a destiniaiton file to be writen by file sink.
|
|
int32_t | filesink_set_write_mode (ElementHandle element, uint8_t write_mode) |
| Set the raw write mode or the packet header mode to write to file.
