Detailed Description

Base class for the video-decoders.

All decoder classes must be derived from this class.

Constructor & Destructor Documentation

virtual CGUIVideoDecoder::~CGUIVideoDecoder ( )

inlinevirtual

Virtual destructor.

CGUIVideoDecoder::CGUIVideoDecoder ( )

inlineprotected

Constructor of CGUIImageDecoder, which sets all supported image types to False.

Member Function Documentation

virtual eC_Bool CGUIVideoDecoder::Decode ( CGUIVideoData &  kImageData, eC_File *  pTmpImgFile  )

pure virtual

Must be implemented in each derived class to decode an image.

Parameters

kImageData	The decoded image has to be stored here by each derived implementation.
pTmpImgFile	Pointer to image file to load.

Returns

Implementations must return True if the image was decoded successfully, False if anything went wrong and the contents of kImageData are invalid.

Implemented in CGUIVideoDecoderMJPEG.

virtual void CGUIVideoDecoder::DecodeFrame ( const eC_UByte *const  pkData, const eC_UInt &  uiLength, eC_UByte *  pkDestination  )

pure virtual

Decode a single frame

Parameters

pkData	pointer to data
uiLength	length of frame
pkDestination	destination-address

Implemented in CGUIVideoDecoderMJPEG.

virtual void CGUIVideoDecoder::SetBPP ( const eC_UByte &  ubBPP)

pure virtual

Set bytes per pixel

Parameters

ubBPP

Implemented in CGUIVideoDecoderMJPEG.

virtual void CGUIVideoDecoder::SetDestinationFormat ( const CGUICommonEnums::ImageType_t &  eDestinationFormat)

pure virtual

Set destination color-format. This will be used to convert the video data to the appropriate format.

Parameters

eDestinationFormat

Implemented in CGUIVideoDecoderMJPEG.

void CGUIVideoDecoder::SwapEndianess16 ( eC_UShort &  ubData)

inlineprotected

Swaps 16-bit endianess of the referenced value.

Parameters

[in,out]

ubData

Given value.

void CGUIVideoDecoder::SwapEndianess32 ( eC_UInt &  uiData)

inlineprotected

Swaps 32-bit endianess of the referenced value.

Parameters

[in,out]

uiData

Given value.
