public class RGBDataFileSink
extends Bin

This bin encapsulates a pipeline that allows to encode RGB buffers into a video file. It uses the AppSrc element to inject the buffers into the gst pipeline.

Constructor Detail

RGBDataFileSink

public RGBDataFileSink(java.lang.String name,
                       int width,
                       int height,
                       int fps,

                       java.lang.String muxerStr,
                       java.io.File file)

Creates a new RGBDataFileSink.

Parameters:

name - The name used to identify this RGBDataFileSink.

width - The width of the buffers that will be sent.

height - The height of the buffers that will be sent.

fps - The framerate with which the buffers should be saved to file.

encoderStr - The name of the encoder to use.

encoderPropertyNames - Array of property names for the encoder.

encoderPropertyData - Array of property values for the encoder.

muxerStr - The name of the muxer to use

file - Output file where the stream is saved to.

Method Detail

pushRGBFrame

public void pushRGBFrame(Buffer buf)

Pushes a buffer down the pipeline.

Parameters:

buf - The buffer to push. Actually, it is not immediatelly pushed into the gst pipeline, but it is added to a fifo linked list that holds the buffer temporarily until the AppSrc requests more data for its internal queue.

start

public void start()

Sets the state of the pipeline to PLAYING.

stop

public void stop()

Sets the state of the pipeline to PAUSED.

setQueueSize

public void setQueueSize(int nFrames)

Sets the size of the AppSrc queue.

Parameters:

nFrames - Size of the queue expressed in number of frames.

getQueueSize

public int getQueueSize()

Returns the current size of the AppSrc queue.

getNumQueuedFrames

public int getNumQueuedFrames()

Returns the number of buffers currently stored in the fifo linked list (still not pushed down the pipeline).
