Value:
omx_base_component_PrivateType_FIELDS \ \ OMX_BUFFERHEADERTYPE* pPendingOutputBuffer; \ \ void (*BufferMgmtCallback)(OMX_COMPONENTTYPE* openmaxStandComp, OMX_BUFFERHEADERTYPE* inputbuffer, OMX_BUFFERHEADERTYPE* outputbuffer);

| void* omx_base_filter_BufferMgmtFunction | ( | void * | param | ) |
This is the central function for component processing. 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.
