Detailed Description

This class loads video files and save them into a 3D texture.

This class can load video files into a BYTE-Array and transfer this array into a 3D texture. It is derived from the CVideoFrameLoader class. It uses the windows media foundation framework and should work under Windows 7, 8 and later. It can load all frames of a video file, all frames after an offset or single frames with a given distance to the last loaded frame.

Constructor & Destructor Documentation

CVideoFrameToTextureLoader::CVideoFrameToTextureLoader ( )

This is the default constructor.

It simple initialises the object. To open a video file you can use the other constructor, the setVideoPath(PWSTR filePath) method or the setVideoURL(PWSTR fileURL) method.

See Also: CVideoFrameToTextureLoader(PWSTR filePath), setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL)

Definition at line 3 of file VideoFrameToTextureLoader.cpp.

CVideoFrameToTextureLoader::CVideoFrameToTextureLoader ( PWSTR filePath)

Constructor to load a file.

Initialises the object and loads the specified file.

Parameters

filePath a pointer to a WSTR which contains the path to the video file in windows syntax

See Also: CVideoFrameToTextureLoader(), setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL)

Definition at line 8 of file VideoFrameToTextureLoader.cpp.

CVideoFrameToTextureLoader::~CVideoFrameToTextureLoader ( void )

Destructor.

Cleans up all reserved memory.

Member Function Documentation

VFLResult CVideoFrameToTextureLoader::loadAllFramesIntoTexture ( )

Loads all video frames of the opend video file and transfers it into the bound texture.

The frames will be saved into a BYTE buffer. The buffer is then transfered into a 3D texture. You have to bind an apropriate texture before calling this method.

Returns: returns VFL_NO_MORE_FRAMES if the operation succeded and the video has ended.

See Also: loadAllFramesIntoTexture(int offset, int distanceBetween), loadAllFramesIntoTexture(int offset, int distanceBetween, int lastFrame); setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL), CVideoFrameToTextureLoader(PWSTR filePath); transferVideoBufferToTexture()

Definition at line 18 of file VideoFrameToTextureLoader.cpp.

VFLResult CVideoFrameToTextureLoader::loadAllFramesIntoTexture	(	int	offset,
		int	distanceBetween
	)

Loads all video frames with offset and distance between and transfers it into the bound texture.

The frames will be saved into a BYTE buffer. The buffer is then transfered into a 3D texture. You have to bind an apropriate texture before calling this method.

Parameters

offset	an integer value starting by 0 that specifies the offset of frames from the start of the video
distanceBetween	an integer value the specifies the number of frames between to frames, that are left out

Returns: returns VFL_NO_MORE_FRAMES if the operation succeded and the video has ended.

See Also: loadAllFramesIntoTexture(), loadAllFramesIntoTexture(int offset, int distanceBetween, int lastFrame); setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL), CVideoFrameToTextureLoader(PWSTR filePath); transferVideoBufferToTexture()

Definition at line 23 of file VideoFrameToTextureLoader.cpp.

VFLResult CVideoFrameToTextureLoader::loadAllFramesIntoTexture	(	int	offset,
		int	distanceBetween,
		int	lastFrame
	)

Loads all video frames with offset, distance between and sets a last frame and transfers it into the bound texture.

The frames will be saved into a BYTE buffer. The buffer is then transfered into a 3D texture. You have to bind an apropriate texture before calling this method.

Parameters

offset	an integer value starting by 0 that specifies the offset of frames from the start of the video
distanceBetween	an integer value the specifies the number of frames between to frames, that are left out
lastFrame	an inteber value specifying the last frame that should be read; if 0 the method reads till the last frame of the video file

Returns: returns VFL_OK if the operation succeded or VFL_NO_MORE_FRAMES if the operation succeded and the video has ended

See Also: loadAllFramesIntoTexture(), loadAllFramesIntoTexture(int offset, int distanceBetween); setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL), CVideoFrameToTextureLoader(PWSTR filePath); transferVideoBufferToTexture()

Definition at line 28 of file VideoFrameToTextureLoader.cpp.

VFLResult CVideoFrameToTextureLoader::resetProperties ( )

protectedvirtual

Completly resets the object.

This virtual method is called to reset the reset all neccessary member properties bevor a new video file is loaded. Overwrite this method to reset your own properties before a new video file is loaded, if you derive from this class.

Returns: returns VFL_OK;

See Also: reset(); setVideoPath(PWSTR filePath), setVideoURL(PWSTR fileURL), CVideoFrameLoader(PWSTR filePath)

Reimplemented from CVideoFrameLoader.

Definition at line 79 of file VideoFrameToTextureLoader.cpp.

VFLResult CVideoFrameToTextureLoader::transferVideoBufferToTexture ( )

Transfers the video buffer byte array into a previously bound texture.

The video array is transfered into a 3D texture. You have to bind an apropriate texture before calling this method.

Returns: returns VFL_OK if the operation succeeded

See Also: loadAllFramesIntoBuffer(), loadAllFramesIntoBuffer(int offset, int distanceBetween), loadAllFramesIntoBuffer(int offset, int distanceBetween, int lastFrame); addNextFrameToBuffer(), addNextFrameToBuffer(int distanceFromLast)
