Public Member Functions
virtual VIDStreamResult	Read (uint8 *pRequestedDataBuffer, uint32 requestedDataBytes, uint32 &actualDataBytes)=0
virtual bool	IsEof ()=0

Detailed Description

Interface for stream communcation between decoder and actual data provider.

Member Function Documentation

IsEof()

virtual bool vdecmpeg4::VIDStreamIO::IsEof ( )

pure virtual

Check if stream is at eof

Returns

True if stream is at eof

Implemented in AVEncoder::FVideoDecoderMPEG4_Impl.

Read()

virtual VIDStreamResult vdecmpeg4::VIDStreamIO::Read ( uint8 *  pRequestedDataBuffer, uint32  requestedDataBytes, uint32 &  actualDataBytes  )

pure virtual

Read data from stream

The decoder calls this method for reading 'requestedDataBytes' from the stream to the memory pointed via 'pRequestedDataBuffer'. The real amount of data which can be returned needs to be assigned to 'actualDataBytes' and a proper VIDStreamResult must be returned.

Parameters

pRequestedDataBuffer	where to put the read data
requestedDataBytes	actual size request of the decoder
actualDataBytes	available number of bytes in buffer after read

Returns

VIDStreamResult

Implemented in AVEncoder::FVideoDecoderMPEG4_Impl.
