Function Documentation
| int jitter_buffer_ctl | ( | JitterBuffer * | jitter, |
| int | request, | ||
| void * | ptr | ||
| ) |
Used like the ioctl function to control the jitter buffer parameters.
- Parameters:
-
jitter Jitter buffer state request ioctl-type request (one of the JITTER_BUFFER_* macros) ptr Data exchanged to-from function
- Returns:
- 0 if no error, -1 if request in unknown
| void jitter_buffer_destroy | ( | JitterBuffer * | jitter ) |
Destroys jitter buffer.
- Parameters:
-
jitter Jitter buffer state
| int jitter_buffer_get | ( | JitterBuffer * | jitter, |
| JitterBufferPacket * | packet, | ||
| spx_int32_t * | start_offset | ||
| ) |
Get one packet from the jitter buffer.
- Parameters:
-
jitter Jitter buffer state packet Returned packet current_timestamp Timestamp for the returned packet
| int jitter_buffer_get_pointer_timestamp | ( | JitterBuffer * | jitter ) |
Get pointer timestamp of jitter buffer.
- Parameters:
-
jitter Jitter buffer state
| JitterBuffer* jitter_buffer_init | ( | int | tick ) |
Initialises jitter buffer.
- Parameters:
-
tick Number of samples per "tick", i.e. the time period of the elements that will be retrieved
- Returns:
- Newly created jitter buffer state
| void jitter_buffer_put | ( | JitterBuffer * | jitter, |
| const JitterBufferPacket * | packet | ||
| ) |
Put one packet into the jitter buffer.
- Parameters:
-
jitter Jitter buffer state packet Incoming packet
| void jitter_buffer_reset | ( | JitterBuffer * | jitter ) |
Restores jitter buffer to its original state.
- Parameters:
-
jitter Jitter buffer state
| void jitter_buffer_tick | ( | JitterBuffer * | jitter ) |
Advance by one tick.
- Parameters:
-
jitter Jitter buffer state
