Public Methods

Method Description
AddFrame ( Bitmap bmp ) : void

Add one frame to a new stream

This works only with uncompressed streams, and compressed streams that have not been saved yet. Use DecompressToNewFile to edit saved compressed streams.

DecompressToNewFile ( String fileName, bool recompress, VideoStream &newStream2 ) : AviManager

Copy all frames into a new file

Use this method if you want to append frames to an existing, compressed stream

ExportBitmap ( int position, String dstFileName ) : void

Export a frame into a bitmap file
ExportStream ( String fileName ) : void

Copy the stream into a new file
GetBitmap ( int position ) : Bitmap

Export a frame into a bitmap
GetFrameClose ( ) : void

Free ressources that have been used by GetFrameOpen
GetFrameOpen ( ) : void

Prepare for decompressing frames

This method has to be called before GetBitmap and ExportBitmap. Release ressources with GetFrameClose.

VideoStream ( int aviFile, Avi compressOptions, double frameRate, Bitmap firstFrame ) : System

Initialize a new VideoStream and add the first frame
VideoStream ( int aviFile, IntPtr aviStream ) : System

Initialize a VideoStream for an existing stream
VideoStream ( int aviFile, bool writeCompressed, double frameRate, Bitmap firstFrame ) : System

Initialize a new VideoStream and add the first frame
VideoStream ( int aviFile, bool writeCompressed, double frameRate, int frameSize, int width, int height, PixelFormat format ) : System

Initialize an empty VideoStream

Private Methods

Method Description
ConvertBitCountToPixelFormat ( int bitCount ) : PixelFormat

Returns a PixelFormat value for a specific bit count
ConvertPixelFormatToBitCount ( PixelFormat format ) : Int16

Get the count of bits per pixel from a PixelFormat value
CreateCompressedStream ( ) : void

Create a compressed stream from an uncompressed stream
CreateCompressedStream ( Avi options ) : void

Create a compressed stream from an uncompressed stream
CreateStream ( ) : void

Create a new stream
CreateStream ( Avi options ) : void

Create a new stream
CreateStreamWithoutFormat ( ) : void

Create a new stream
GetRateAndScale ( double &frameRate, int &scale ) : void
GetStreamInfo ( IntPtr aviStream ) : Avi.AVISTREAMINFO
Initialize ( int aviFile, bool writeCompressed, double frameRate, Bitmap firstFrameBitmap ) : void

Initialize a new VideoStream

Used only by constructors

SetFormat ( IntPtr aviStream ) : void

Apply a format to a new stream

The format must be set before the first frame can be written, and it cannot be changed later.

VideoStream ( int frameSize, double frameRate, int width, int height, Int16 countBitsPerPixel, int countFrames, Avi compressOptions, bool writeCompressed ) : System

Copy all properties from one VideoStream to another one

Used by EditableVideoStream
