OMX_BOOL 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 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.

OMX_DIRTYPE eDir

Direction (input or output) of this port

Domain of the port. Determines the contents of metadata below.

union { ... } format

OMX_U32 nBufferCountMin

The minimum number of buffers this port requires

OMX_U32 nBufferSize

Size, in bytes, for buffers to be used for this channel

OMX_U32 nPortIndex

Port number the structure applies to

OMX_U32 nSize
