Public Methods

Method	Description
Dispose ( ) : void	Releases all managed and unmanaged resources
FFmpegMedia ( string filePath, MediaErrorOccurredCallback errorCallback ) : FFmpeg.AutoGen	Initializes a new instance of the FFmpegMedia class.
FFmpegMedia ( string filePath, MediaErrorOccurredCallback errorCallback, string referer, string userAgent ) : FFmpeg.AutoGen	Initializes a new instance of the FFmpegMedia class.
RenderAudioBuffer ( byte bufferToFill, int &bytesWritten ) : bool	Renders the audio buffer. This is the implementation of IAudioDataProvider.RenderAudioBufferMethod It basically gets the decoded PCM bytes from the audio buffer provider. This method is called by the audio device itself.

Private Methods

Method	Description
CreateMediaFrameFromDecodedPictureHolder ( ) : FFmpegMediaFrame
CreateMediaFrameFromDecodedWaveHolder ( ) : FFmpegMediaFrame
ExtractMediaFramesContinuously ( ) : void	Extracts the media frames continuously.
FillDecodedPictureHolderFrame ( AVPacket readingPacket, bool emptyPacket ) : bool
FillDecodedWaveHolderFrame ( AVPacket readingPacket, bool emptyPacket ) : bool
InitializeAudio ( ) : void	Initializes the audio.
InitializeMedia ( string filePath, string inputFormatName, string referer, string userAgent ) : void	Initializes the internal transcoder -- This create the input, processing, and output blocks that make up the video and audio decoding stream.
InitializeVideo ( ) : void
InternalFillFramesCache ( System.TimeSpan timeout ) : void
InternalLoadFrames ( decimal renderTime ) : void
InternalSeekInput ( decimal renderTime ) : void	Internals the seek input.
PullMediaFrame ( ) : FFmpegMediaFrame	Pulls the next-available frame. This does not queue the frame in either the video or audio queue. Please keep in mind that you will need to manually call the Release() method the returned object are done with it. If working with Media Caches, the cache will automatically release the frame
RenderVideoImage ( object sender, EventArgs e ) : void	Renders the video image. This method is called on a Dispatcher timer. It is responsible for rendering the decoded video image continuously. It also avoids rendering the same image again.
StartAudioRenderer ( ) : void
