org.gstreamer.elements.RGBDataFileSink

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 encoderStr,
               java.lang.String[] encoderPropertyNames,

               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 immediately 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 StateChangeReturn start()

Sets the state of the pipeline to PLAYING.

stop

public StateChangeReturn stop()

Sets the state of the pipeline to NULL and closes the stream.

Overrides:

stop in class Element

setPreQueueSize

public void setPreQueueSize(int nFrames)

Sets the size of the pre-encoding queue, which is stored on the Java side.

Parameters:

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

getPreQueueSize

public int getPreQueueSize()

Returns the size of the pre-encoding queue.

getNumQueuedFrames

public int getNumQueuedFrames()

Returns the number of frames currently stored in pre-encoding queue, still not sent to the encoding pipeline.

setSrcQueueSize

public void setSrcQueueSize(int nFrames)

Sets the size of the AppSrc queue.

Parameters:

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

getSrcQueueSize

public int getSrcQueueSize()

Returns the current size of the AppSrc queue.

getNumDroppedFrames

public int getNumDroppedFrames()

Returns the number of dropped frames until now.
