static uint8_t | audiosink_sink_pad_activation_handler (StreamPad *pad, uint8_t active) |
| This function activates the sink pad and allocates memory for the audio sink element.
|
|
static FlowReturn | audiosink_sink_pad_chain_handler (StreamPad *pad, StreamBuffer *buffer) |
| 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 | audiosink_sink_pad_process_handler (StreamPad *pad) |
| Function is the loop function of the audio sink pad which runs in the task thread. It reads the chunk_size of data and pushes it to peer element sink pad.
|
|
static uint8_t | audiosink_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 | audiosink_change_state (StreamElement *element, PipelineState new_state) |
| This function changes the audio sink state and calls the appropriate apis for that state and takes the actions and then returns. PipelineState Transition: NULL to READY: Initialize audio device (now, playback only) READY to PAUSE: Activate sink pads and their peer pads PAUSE to PLAY: Start Playing.
|
|
static uint8_t | audiosink_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 | audiosink_get_property (StreamElement *element_ptr, uint16_t prop, uint32_t *val_ptr) |
| This function gets audio sink element's properties.
|
|
static int32_t | audiosink_set_property (StreamElement *element_ptr, uint16_t prop, uint32_t val) |
| This function sets audio sink element's properties.
|
|
int32_t | audiosink_init_element (StreamElement *element) |
| This function initializes audio sink element and its sink pads.
|
|
AudioSinkStreamErrorType | audiosink_set_device_driver_type (ElementHandle element, AudioSinkDeviceDriverType device_driver_type) |
| This function sets the audio driver type as SSI or ALSA. Now, only a SSI interface is implemented.
|
|
AudioSinkStreamErrorType | audiosink_set_device_name (ElementHandle element, AudioSinkDeviceName device_name) |
| This function sets the audio device name. This API is provided just in case an enumeration is done by ALSA or OSS probably before opening the device.
|
|
AudioSinkStreamErrorType | audiosink_set_device_string_name (ElementHandle element, char *device_string_name) |
| This function sets the audio device string name.
