Class MediaVideoBufferEncoder

java.lang.Object

com.serenegiant.encoder.MediaEncoder

com.serenegiant.encoder.MediaVideoBufferEncoder

All Implemented Interfaces:

IVideoEncoder, java.lang.Runnable

public class MediaVideoBufferEncoder
extends MediaEncoder
implements IVideoEncoder

This class receives video images as ByteBuffer(strongly recommend direct ByteBuffer) as NV21(YUV420SP) and encode them to h.264. If you use this directly with IFrameCallback, you should know UVCCamera and it backend native libraries never execute color space conversion. This means that color tone of resulted movie will be different from that you expected/can see on screen.
