OMX_IN is used to identify inputs to an OMX function. This designation will also be used in the case of a pointer that points to a parameter that is used as an output. OMX_OUT is used to identify outputs from an OMX function. This designation will also be used in the case of a pointer that points to a parameter that is used as an input. OMX_INOUT is used to identify parameters that may be either inputs or outputs from an OMX function at the same time. This designation will also be used in the case of a pointer that points to a parameter that is used both as an input and an output. OMX_ALL is used to as a wildcard to select all entities of the same type when specifying the index, or referring to a object by an index. (i.e. use OMX_ALL to indicate all N channels). When used as a port index for a config or parameter this OMX_ALL denotes that the config or parameter applies to the entire component not just one port.

| #define OMX_API extern |
OMX_Types.h - OpenMax IL version 1.1.1 The OMX_Types header file contains the primitive type definitions used by the core, the application and the component. This file may need to be modified to be used on systems that do not have "char" set to 8 bits, "short" set to 16 bits and "long" set to 32 bits. The OMX_API and OMX_APIENTRY are platform specific definitions used to declare OMX function prototypes. They are modified to meet the requirements for a particular platform

| #define OMX_TICKS_PER_SECOND 1000000 |
Definition at line 292 of file OMX_Types.h.
| typedef unsigned char* OMX_BYTE |
The OMX_BYTE type is intended to be used to pass arrays of bytes such as buffers between the application and the component and core. The OMX_BYTE type is a 32 bit pointer to a zero terminated string. The pointer is word aligned and the string is byte aligned.
Definition at line 215 of file OMX_Types.h.
| typedef void* OMX_HANDLETYPE |
Define the public interface for the OMX Handle. The core will not use this value internally, but the application should only use this value.
Definition at line 297 of file OMX_Types.h.
| typedef void* OMX_NATIVE_DEVICETYPE |
OMX_NATIVE_DEVICETYPE is used to map a OMX video port to the platform & operating specific object used to reference the display or can be used by a audio port for native audio rendering
Definition at line 313 of file OMX_Types.h.
| typedef void* OMX_NATIVE_WINDOWTYPE |
OMX_NATIVE_WINDOWTYPE is used to map a OMX video port to the platform & operating specific object used to reference the window
Definition at line 317 of file OMX_Types.h.
| typedef void* OMX_PTR |
The OMX_PTR type is intended to be used to pass pointers between the OMX applications and the OMX Core and components. This is a 32 bit pointer and is aligned on a 32 bit boundary.
Definition at line 201 of file OMX_Types.h.
| typedef signed short OMX_S16 |
OMX_S16 is a 16 bit signed quantity that is 16 bit word aligned
Definition at line 144 of file OMX_Types.h.
| typedef signed long OMX_S32 |
OMX_S32 is a 32 bit signed quantity that is 32 bit word aligned
Definition at line 150 of file OMX_Types.h.
| typedef signed long long OMX_S64 |
OMX_S64 is a 64 bit signed quantity that is 64 bit word aligned
Definition at line 181 of file OMX_Types.h.
| typedef signed char OMX_S8 |
OMX_S8 is an 8 bit signed quantity that is byte aligned
Definition at line 138 of file OMX_Types.h.
| typedef char* OMX_STRING |
The OMX_STRING type is intended to be used to pass "C" type strings between the application and the core and component. The OMX_STRING type is a 32 bit pointer to a zero terminated string. The pointer is word aligned and the string is byte aligned.
Definition at line 208 of file OMX_Types.h.
Structure representing some time or duration in microseconds. This structure must be interpreted as a signed 64 bit value. The quantity is signed to accommodate negative deltas and preroll scenarios. The quantity is represented in microseconds to accomodate high resolution timestamps (e.g. DVD presentation timestamps based on a 90kHz clock) and to allow more accurate and synchronized delivery (e.g. individual audio samples delivered at 192 kHz). The quantity is 64 bit to accommodate a large dynamic range (signed 32 bit values would allow only for plus or minus 35 minutes).
Implementations with limited precision may convert the signed 64 bit value to a signed 32 bit value internally but risk loss of precision.

| typedef unsigned short OMX_U16 |
OMX_U16 is a 16 bit unsigned quantity that is 16 bit word aligned
Definition at line 141 of file OMX_Types.h.
| typedef unsigned long OMX_U32 |
OMX_U32 is a 32 bit unsigned quantity that is 32 bit word aligned
Definition at line 147 of file OMX_Types.h.
| typedef unsigned long long OMX_U64 |
OMX_U64 is a 64 bit unsigned quantity that is 64 bit word aligned
Definition at line 178 of file OMX_Types.h.
| typedef unsigned char OMX_U8 |
OMX_U8 is an 8 bit unsigned quantity that is byte aligned
Definition at line 135 of file OMX_Types.h.
| typedef unsigned char OMX_UUIDTYPE[128] |
OMX_UUIDTYPE is a very long unique identifier to uniquely identify at runtime. This identifier should be generated by a component in a way that guarantees that every instance of the identifier running on the system is unique.
Definition at line 221 of file OMX_Types.h.
| enum OMX_BOOL |
The OMX_BOOL type is intended to be used to represent a true or a false value when passing parameters to and from the OMX core and components. The OMX_BOOL is a 32 bit quantity and is aligned on a 32 bit word boundary.
Definition at line 191 of file OMX_Types.h.
| enum OMX_DIRTYPE |
The OMX_DIRTYPE enumeration is used to indicate if a port is an input or an output port. This enumeration is common across all component types.
Definition at line 226 of file OMX_Types.h.
| enum OMX_ENDIANTYPE |
The OMX_ENDIANTYPE enumeration is used to indicate the bit ordering for numerical data (i.e. big endian, or little endian).
Definition at line 236 of file OMX_Types.h.
The OMX_NUMERICALDATATYPE enumeration is used to indicate if data is signed or unsigned
| OMX_NumericalDataSigned | signed data |
