IPvH264AccessUnit
Generic, read-only H264 access unit interface.
Definition: PvH264AccessUnit.h:32
IPvH264AccessUnit::Free
virtual void Free()=0
Frees (de-allocates) the buffer's internal memory.
IPvH264AccessUnit::GetNALCount
virtual uint32_t GetNALCount() const =0
Returns how many NALs are currently stored in the access unit.
IPvH264AccessUnit::GetHeight
virtual uint32_t GetHeight() const =0
Width of the image represented by this access unit.
IPvH264AccessUnit::GetNALDataPtr
virtual const uint8_t * GetNALDataPtr() const =0
Returns a pointer to the raw NAL data buffer.
IPvH264AccessUnit::Alloc
virtual PvResult Alloc(uint64_t aPayloadLength, uint32_t aMaximumChunkLength=0)=0
Allocates memory for this access unit.
IPvH264AccessUnit::GetWidth
virtual uint32_t GetWidth() const =0
Width of the image represented by this access unit.
IPvH264AccessUnit::AddNAL
virtual PvResult AddNAL(const uint8_t *aPtr, uint32_t aLength)=0
Copies a NAL to this access unit.
IPvH264AccessUnit::GetSize
virtual uint32_t GetSize() const =0
Returns the total buffer size, including chunk and/or unused space.
IPvH264AccessUnit::CopyNALData
virtual PvResult CopyNALData(const uint8_t *aPtr, uint32_t aLength, uint32_t aWidth, uint32_t aHeight)=0
Copies NAL data to the buffer.
IPvH264AccessUnit::GetNALDataSize
virtual uint32_t GetNALDataSize() const =0
Returns the total raw NAL data size.
IPvH264AccessUnit::GetNALPtr
virtual PvResult GetNALPtr(uint32_t aIndex, const uint8_t **aPtr, uint32_t &aLength) const =0
Returns a pointer to a NAL stored in this access unit.
