C# 클래스 AForge.Video.MJPEGStream

MJPEG video source.

The video source downloads JPEG images from the specified URL, which represents MJPEG stream.

Sample usage:

 // create MJPEG video source MJPEGStream stream = new MJPEGStream( "some url" ); // set event handlers stream.NewFrame += new NewFrameEventHandler( video_NewFrame ); // start the video source stream.Start( ); // ... // signal to stop stream.SignalToStop( );

Some cameras produce HTTP header, which does not conform strictly to standard, what leads to .NET exception. To avoid this exception the useUnsafeHeaderParsing configuration option of httpWebRequest should be set, what may be done using application configuration file.

 <configuration> <system.net> <settings> <httpWebRequest useUnsafeHeaderParsing="true" /> </settings> </system.net> </configuration>

메소드	설명
MJPEGStream ( ) : System	Initializes a new instance of the MJPEGStream class.
MJPEGStream ( string source ) : System	Initializes a new instance of the MJPEGStream class.
SignalToStop ( ) : void	Signal video source to stop its work. Signals video source to stop its background thread, stop to provide new frames and free resources.
Start ( ) : void	Start video source. Starts video source and return execution to caller. Video source object creates background thread and notifies about new frames with the help of NewFrame event.
Stop ( ) : void	Stop video source. Stops video source aborting its thread. Since the method aborts background thread, its usage is highly not preferred and should be done only if there are no other options. The correct way of stopping camera is signaling it stop and then waiting for background thread's completion.
WaitForStop ( ) : void	Wait for video source has stopped. Waits for source stopping after it was signalled to stop using SignalToStop method.
