C# Class HCS_Encoder.Utilities.EncoderController

This class provides a simplified way to start and stop an encode process, using a configuration file for the details.

Inheritance: IDisposable

Public Methods

Method	Description
ClearBuffers ( ) : void	Clear all captured frames from all attached buffers. Buffers will refill if capture devices are running.
ContinueCapture ( ) : void	Resumes capture devices after a call to 'PauseCapture()'
ContinueOutput ( int MinimumChunkIndex ) : void	Resumes output sending (if 'EnableOutput' is false). Any chunks with an index below 'MiniumumChunkIndex' will be dropped.
Dispose ( ) : void
EncoderController ( Configuration Config ) : System	Create and initialise a new encoder job with the given config
ForceInsertFrame ( System VideoFrame, double SimulatedCaptureTime ) : void	Force a timed frame into the encoder's buffers. May cause unexpected operation. Use with caution!
ForceInsertFrame ( TimedSample AudioFrame ) : void	Force a timed frame into the encoder's buffers. May cause unexpected operation. Use with caution!
PauseCapture ( ) : void	Pauses all capture devices, but allows the encoder loop to continue (will sleep while buffers are empty)
RegisterPlugin ( IAudioProcessor PlugIn ) : void	Add a plug-in to the audio buffer's plug-in list
RegisterPlugin ( IVideoProcessor PlugIn ) : void	Add a plug-in to the video buffer's plug-in list
Start ( ) : void	Start the encoding process. This will start to over-write any existing encodes made with the configuration being used.
Stop ( ) : void	Stop the encoding process

Private Methods

Method	Description
AdjustFrameSleep ( ) : void	Work out a resonable sleep duration (over which we'd expect a new frame in at least one buffer)
BuffersEmpty ( ) : bool	Returns true if any of the active capture buffers are below their encoding theshold.
CalculateScales ( int Width, int Height, List ScaleFactors ) : List	Given a set of linear scale factors, create a set of scaled (w*h) sizes. Scaling the height and width directly will result in pixel count being reduced by the square of the scale factor, so instead we apply a rough factor to get a linear scaled pixel count.
CaptureSetup ( ) : void	Initialise capture devices and connect the appropriate buffers
ConnectPackageToBuffers ( EncoderPackage Package, PackageSpec Spec ) : void	Create encoder buffers for each package, and add to capture buffer lists.
EncoderCoreLoop ( object Package ) : void	This loop does the actual work of reading caches into the encoder and firing actions. This loop controls Multiple-bit-rate encoding
EncoderSetup ( ) : void	Initialise an encoder job based on previously setup capture devices. Need to have one job per 'ReductionFactor' in the config.
Halt ( ) : void	Stop the encode process, from within the core loop
InitAudioCapture ( ) : void
InitVideoCapture ( ) : void
InnerStartup ( ) : void	Start encoder threads & capture devices for each job.
ListRequiredPackages ( ) : List	Creates a list of encoder packages requires to fulfill the configured job.
NewEncoderThread ( EncoderPackage pkg ) : Thread	Create, start and return a new core encoder thread.
WaitAndCompensateCaptureTimes ( ) : void	Wait for first frames in buffer, and use those to compensate timecodes.
WaitForSyncFlag ( ) : void	Wait for the sync flag to be set by WaitAndCompensateCaptureTimes()
