OMX_BOOL OMX_PARAM_PORTDEFINITIONTYPE::bEnabled

Ports default to enabled and are enabled/disabled by OMX_CommandPortEnable/OMX_CommandPortDisable. When disabled a port is unpopulated. A disabled port is not populated with buffers on a transition to IDLE.

OMX_BOOL OMX_PARAM_PORTDEFINITIONTYPE::bPopulated

Port is populated with all of its buffers as indicated by nBufferCountActual. A disabled port is always unpopulated. An enabled port is populated on a transition to OMX_StateIdle and unpopulated on a transition to loaded.
