| void* omx_audio_mixer_BufferMgmtFunction | ( | void * | param | ) |
This is the central function for component processing,overridden for audio mixer. It is executed in a separate thread, is synchronized with semaphores at each port, those are released each time a new buffer is available on the given port.
