10. Media

ARGear provides image or video capture through ARGMedia. Users can take a photo or shoot a video in the available ratios, 16:9, 4:3, 1:1.
10.1 Take a Photo
Using the takePicture function in ARGMedia, users can take a photo.
The function must be called in gl thread environment.
Sample code is written below.
Java
Kotlin
Java
ARGMedia argmedia = new ARGMedia(argsession);
​
GLView.GLViewListener glViewListener = new GLView.GLViewListener() {
​
    @Override
    public void onDrawFrame(GL10 gl, int width, int height) {
​
        ARGFrame frame = mARGSession.drawFrame(gl, width, height);
        if (argmedia != null) {
            if (mIsShooting) {
                String path = Environment.getExternalStorageDirectory() + "/" + System.currentTimeMillis() + ".jpg";
                argmedia.takePicture(frame.getTextureId(), path, ARGMedia.Ratio.RATIO_4_3);
            }
        }
​
    }
};
Kotlin
var argmedia = ARGMedia(argsession)
​
override fun onDrawFrame(gl: GL10?, width: Int?, height: Int?) {
​
    val localWidth = width ?: 0
    val localHeight = height ?: 0
    val frame = argsession.drawFrame(gl, localWidth, localHeight)
    frame?.let {
        if (isShooting) {
            val path = mediaPath + "/" + System.currentTimeMillis() + ".jpg"
            argmedia.takePicture(textureId, path, ARGMedia.Ratio.RATIO_4_3)
        }
    }
    
}

10.2 Record a Video
ARGMedia provides several functions to record a video. Through the functions you can control bitrate, silent mode, and video frame size ratio.
Sample code to record a video is written below.
Java
Kotlin
Java
ARGMedia argmedia = new ARGMedia(argsession);
​
private void startRecording() {
    int bitrate = 10 * 1000 * 1000; // 10M
    int [] previewSize = mCamera.getPreviewSize();
    mVideoFilePath = Environment.getExternalStorageDirectory() + "/" + System.currentTimeMillis() + ".mp4";
​
   // Initiate Recorder
    argmedia.initRecorder(mVideoFilePath, 
                                        previewSize[0], previewSize[1], bitrate,
                                        false, false, false, ARGMedia.Ratio.RATIO_4_3);
    // Start Recording
    argmedia.startRecording();
}
​
private void stopRecording() {
    // Stop Recording
    argmedia.stopRecording();
}
​
GLView.GLViewListener glViewListener = new GLView.GLViewListener() {
​
    @Override
    public void onDrawFrame(GL10 gl, int width, int height) {
​
        ARGFrame frame = mARGSession.drawFrame(gl, width, height);
        if (argmedia != null && argmedia.isRecording()) {
            // Update Recording Frame
            argmedia.updateFrame(frame.getTextureId());
        }
​
    }
};
Kotlin
var argmedia = new ARGMedia(argsession);
​
private fun startRecording() {
    val bitrate = 10 * 1000 * 1000 // 10M
    val previewSize: IntArray? = camera.previewSize
    val videoFilePath = mediaPath + "/" + System.currentTimeMillis() + ".mp4"
​
    argMedia.initRecorder(
        videoFilePath, previewSize[0], previewSize[1], bitrate,
        false, false, false, ARGMedia.Ratio.RATIO_4_3
    )
​
    argMedia.startRecording()
}
​
private fun stopRecording() {
    argmedia.stopRecording()
}
​
override fun onDrawFrame(gl: GL10?, width: Int?, height: Int?) {
​
    val localWidth = width ?: 0
    val localHeight = height ?: 0
    val frame = argsession.drawFrame(gl, localWidth, localHeight)
    frame?.let {
        if (argmedia.isRecording) argmedia.updateFrame(it.textureId)
    }
}
