Enumeration Type Documentation

enum OMX_ERRORTYPE

The OMX_ERRORTYPE enumeration defines the standard OMX Errors.

These errors should cover most of the common failure cases. However, vendors are free to add additional error messages of their own as long as they follow these rules: 1. Vendor error messages shall be in the range of 0x90000000 to 0x9000FFFF. 2. Vendor error messages shall be defined in a header file provided with the component. No error messages are allowed that are not defined.

Enumerator:

OMX_ErrorNone
OMX_ErrorInsufficientResources	There were insufficient resources to perform the requested operation.
OMX_ErrorUndefined	There was an error, but the cause of the error could not be determined.
OMX_ErrorInvalidComponentName	The component name string was not valid.
OMX_ErrorComponentNotFound	No component with the specified name string was found.
OMX_ErrorInvalidComponent	The component specified did not have a "OMX_ComponentInit" or "OMX_ComponentDeInit entry point.
OMX_ErrorBadParameter	One or more parameters were not valid.
OMX_ErrorNotImplemented	The requested function is not implemented.
OMX_ErrorUnderflow	The buffer was emptied before the next buffer was ready.
OMX_ErrorOverflow	The buffer was not available when it was needed.
OMX_ErrorHardware	The hardware failed to respond as expected.
OMX_ErrorInvalidState	The component is in the state OMX_StateInvalid.
OMX_ErrorStreamCorrupt	Stream is found to be corrupt.
OMX_ErrorPortsNotCompatible	Ports being connected are not compatible.
OMX_ErrorResourcesLost	Resources allocated to an idle component have been lost resulting in the component returning to the loaded state.
OMX_ErrorNoMore	No more indicies can be enumerated.
OMX_ErrorVersionMismatch	The component detected a version mismatch.
OMX_ErrorNotReady	The component is not ready to return data at this time.
OMX_ErrorTimeout	There was a timeout that occurred.
OMX_ErrorSameState	This error occurs when trying to transition into the state you are already in.
OMX_ErrorResourcesPreempted	Resources allocated to an executing or paused component have been preempted, causing the component to return to the idle state.
OMX_ErrorPortUnresponsiveDuringAllocation	A non-supplier port sends this error to the IL client (via the EventHandler callback) during the allocation of buffers (on a transition from the LOADED to the IDLE state or on a port restart) when it deems that it has waited an unusually long time for the supplier to send it an allocated buffer via a UseBuffer call.
OMX_ErrorPortUnresponsiveDuringDeallocation	A non-supplier port sends this error to the IL client (via the EventHandler callback) during the deallocation of buffers (on a transition from the IDLE to LOADED state or on a port stop) when it deems that it has waited an unusually long time for the supplier to request the deallocation of a buffer header via a FreeBuffer call.
OMX_ErrorPortUnresponsiveDuringStop	A supplier port sends this error to the IL client (via the EventHandler callback) during the stopping of a port (either on a transition from the IDLE to LOADED state or a port stop) when it deems that it has waited an unusually long time for the non-supplier to return a buffer via an EmptyThisBuffer or FillThisBuffer call.
OMX_ErrorIncorrectStateTransition	Attempting a state transtion that is not allowed.
OMX_ErrorIncorrectStateOperation
OMX_ErrorUnsupportedSetting	The values encapsulated in the parameter or config structure are not supported.
OMX_ErrorUnsupportedIndex	The parameter or config indicated by the given index is not supported.
OMX_ErrorBadPortIndex	The port index supplied is incorrect.
OMX_ErrorPortUnpopulated	The port has lost one or more of its buffers and it thus unpopulated.
OMX_ErrorComponentSuspended	Component suspended due to temporary loss of resources.
OMX_ErrorDynamicResourcesUnavailable	Component suspended due to an inability to acquire dynamic resources.
OMX_ErrorMbErrorsInFrame	When the macroblock error reporting is enabled the component returns new error for every frame that has errors.
OMX_ErrorFormatNotDetected	A component reports this error when it cannot parse or determine the format of an input stream.
OMX_ErrorContentPipeOpenFailed	The content open operation failed.
OMX_ErrorContentPipeCreationFailed	The content creation operation failed.
OMX_ErrorSeperateTablesUsed	Separate table information is being used.
OMX_ErrorTunnelingUnsupported	Tunneling is unsupported by the component.
OMX_ErrorKhronosExtensions	Reserved region for introducing Khronos Standard Extensions.
OMX_ErrorVendorStartUnused	Reserved region for introducing Vendor Extensions.
OMX_ErrorMax

enum OMX_EXTRADATATYPE

The OMX_EXTRADATATYPE enumeration is used to define the possible extra data payload types.

NB: this enum is binary backwards compatible with the previous OMX_EXTRADATA_QUANT define. This should be replaced with OMX_ExtraDataQuantization.

Enumerator:

OMX_ExtraDataNone	Indicates that no more extra data sections follow.
OMX_ExtraDataQuantization	The data payload contains quantization data.
OMX_ExtraDataKhronosExtensions	Reserved region for introducing Khronos Standard Extensions.
OMX_ExtraDataVendorStartUnused	Reserved region for introducing Vendor Extensions.

Functions
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_Init (void)
	The OMX_Init method is used to initialize the OMX core.
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_Deinit (void)
	The OMX_Deinit method is used to deinitialize the OMX core.
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_ComponentNameEnum (OMX_OUT OMX_STRING cComponentName, OMX_IN OMX_U32 nNameLength, OMX_IN OMX_U32 nIndex)
	The OMX_ComponentNameEnum method will enumerate through all the names of recognised valid components in the system.
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_GetHandle (OMX_OUT OMX_HANDLETYPE pHandle, OMX_IN OMX_STRING cComponentName, OMX_IN OMX_PTR pAppData, OMX_IN OMX_CALLBACKTYPE pCallBacks)
	The OMX_GetHandle method will locate the component specified by the component name given, load that component into memory and then invoke the component's methods to create an instance of the component.
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_FreeHandle (OMX_IN OMX_HANDLETYPE hComponent)
	The OMX_FreeHandle method will free a handle allocated by the OMX_GetHandle method.
OMX_API OMX_ERRORTYPE OMX_APIENTRY	OMX_SetupTunnel (OMX_IN OMX_HANDLETYPE hOutput, OMX_IN OMX_U32 nPortOutput, OMX_IN OMX_HANDLETYPE hInput, OMX_IN OMX_U32 nPortInput)
	The OMX_SetupTunnel method will handle the necessary calls to the components to setup the specified tunnel the two components.
