Field Documentation

◆ hMarkTargetComponent

OMX_HANDLETYPE OMX_BUFFERHEADERTYPE::hMarkTargetComponent

◆ nAllocLen

OMX_U32 OMX_BUFFERHEADERTYPE::nAllocLen

size of the buffer allocated, in bytes

Definition at line 404 of file OMX_Core.h.

Referenced by base_port_AllocateBuffer(), and base_port_UseBuffer().

◆ nFilledLen

◆ nFlags

◆ nInputPortIndex

◆ nOffset

OMX_U32 OMX_BUFFERHEADERTYPE::nOffset

start offset of valid data in bytes from the start of the buffer

Definition at line 407 of file OMX_Core.h.

Referenced by audiomixerEmptyBufferDone(), omx_video_scheduler_component_BufferMgmtCallback(), and volcEmptyBufferDone().

◆ nOutputPortIndex

◆ nSize

OMX_U32 OMX_BUFFERHEADERTYPE::nSize

size of the structure in bytes

Definition at line 400 of file OMX_Core.h.

◆ nTickCount

OMX_U32 OMX_BUFFERHEADERTYPE::nTickCount

Optional entry that the component and application can update with a tick count when they access the component. This value should be in microseconds. Since this is a value relative to an arbitrary starting point, this value cannot be used to determine absolute time. This is an optional entry and not all components will update it.

Definition at line 422 of file OMX_Core.h.

◆ nTimeStamp

OMX_TICKS OMX_BUFFERHEADERTYPE::nTimeStamp

Timestamp corresponding to the sample starting at the first logical sample boundary in the buffer. Timestamps of successive samples within the buffer may be inferred by adding the duration of the of the preceding buffer to the timestamp of the preceding buffer.

◆ nVersion

OMX_VERSIONTYPE OMX_BUFFERHEADERTYPE::nVersion

OMX specification version information

Definition at line 401 of file OMX_Core.h.

◆ pAppPrivate

OMX_PTR OMX_BUFFERHEADERTYPE::pAppPrivate

pointer to any data the application wants to associate with this buffer

Definition at line 409 of file OMX_Core.h.

◆ pBuffer

◆ pInputPortPrivate

OMX_PTR OMX_BUFFERHEADERTYPE::pInputPortPrivate

pointer to any data the input port wants to associate with this buffer

Definition at line 413 of file OMX_Core.h.

◆ pMarkData

OMX_PTR OMX_BUFFERHEADERTYPE::pMarkData

Application specific data associated with the mark sent on a mark event to disambiguate this mark from others.

◆ pOutputPortPrivate

OMX_PTR OMX_BUFFERHEADERTYPE::pOutputPortPrivate

pointer to any data the output port wants to associate with this buffer
