Class VideoEncoderCore

java.lang.Object

app.library.linkflow.rtmp.encoder.VideoEncoderCore

public class VideoEncoderCore
extends java.lang.Object

This class wraps up the core components used for surface-input video encoding.

Once created, frames are fed to the input surface. Remember to provide the presentation time stamp, and always call drainEncoder() before swapBuffers() to ensure that the producer side doesn't get backed up.

This class is not thread-safe, with one exception: it is valid to use the input surface on one thread, and drain the output on a different thread.

Constructor Detail

VideoEncoderCore

public VideoEncoderCore(int width,
                        int height,
                        int bitRate,
                        int frameRate)
                 throws java.io.IOException

Configures encoder and muxer state, and prepares the input Surface.

Throws:

java.io.IOException

                        int height,
                        int bitRate,
                        int frameRate,

                 throws java.io.IOException

Throws:

java.io.IOException

Method Detail

getInputSurface

public android.view.Surface getInputSurface()

Returns the encoder's input surface.

release

public void release()

Releases encoder resources.

drainEncoder

public void drainEncoder(boolean endOfStream)

Extracts all pending data from the encoder and forwards it to the muxer.

If endOfStream is not set, this returns when there is no more data to drain. If it is set, we send EOS to the encoder, and then iterate until we see EOS on the output. Calling this with endOfStream set should be done once, swipe_right before stopping the muxer.

We're just using the muxer to get a .mp4 file (instead of a raw H.264 stream). We're not recording audio.

stopMuxer

public void stopMuxer()
