java – Sending video using rtmp

After my encoder, how can I send the video using rtmp? I found the “rtmp-rtsp-stream-client-java” library but only found examples using the device’s camera.
I already have the ant media server to receive this stream, my problem is just to send it using rtmp.

private void prepareVideoEncoder() {
        mVideoBufferInfo = new MediaCodec.BufferInfo();
        MediaFormat format = MediaFormat.createVideoFormat(VIDEO_MIME_TYPE, VIDEO_WIDTH, VIDEO_HEIGHT);
        int frameRate = 30; // 30 fps

        // Set some required properties. The media codec may fail if these aren't defined.
        format.setInteger(MediaFormat.KEY_COLOR_FORMAT,
                MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);
        format.setInteger(MediaFormat.KEY_BIT_RATE, 6000000); // 6Mbps
        format.setInteger(MediaFormat.KEY_FRAME_RATE, frameRate);
        format.setInteger(MediaFormat.KEY_CAPTURE_RATE, frameRate);
        format.setInteger(MediaFormat.KEY_REPEAT_PREVIOUS_FRAME_AFTER, 1000000 / frameRate);
        format.setInteger(MediaFormat.KEY_CHANNEL_COUNT, 1);
        format.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 1); // 1 seconds between I-frames

        // Create a MediaCodec encoder and configure it. Get a Surface we can use for recording into.
        try {
            mVideoEncoder = MediaCodec.createEncoderByType(VIDEO_MIME_TYPE);
            mVideoEncoder.configure(format, null, null, MediaCodec.CONFIGURE_FLAG_ENCODE);
            mInputSurface = mVideoEncoder.createInputSurface();
            mVideoEncoder.start();
        } catch (IOException e) {
            //releaseEncoders();
            Log.d("TAG", "Erro prepareVideoEncoder:" + e);
        }
    }
