[Android] 使用dd及還原工具進行Android系統的還原
因美國專案人員使用fastboot命令更新rom導致開機失敗(燒壞)，亦無法繼續更新
需線上提供dd image進行緊急燒路更新。 以dd來說是以整張SD卡磁區作為備份image
再利用工具Wim32DiskImager 將備份之image還原至另一張SD卡的方法。適合用於緊急狀況
但也需要相對大的空間(因為是將燒錄後展開的系統整張卡片打包成image的緣故)
dd if=/dev/sdb/ of=./aaa.img bs=512
Stpe2. 格式化SD卡
使用SD Card Formater : https://www.sdcard.org/downloads/index.html
Stpe3. Win32DiskImager : https://sourceforge.net/projects/win32diskimager/
或是使用 USB image tool : https://www.alexpage.de/usb-image-tool/download/

[Android]Camera debug for nv 21 and 12 format
RAW pixels viewer(免安裝的網路資源) : https://rawpixels.net/
7yuv(需下載安裝於電腦中) : http://datahammer.de/
類似RGB的概念 : YUV也是三種色彩元素代稱, Y=明亮度, U=色度, V=濃度
YUV為視訊影像的編碼格式 目前專案僅用到N21與N12兩種格式的驗證應用
YUV文獻 : https://www.itread01.com/content/1542704886.html
N21與N12根據定義為YUV中 UV順序相反，
N21為Y填完再用UV交替填完，例 : YYYYVUVUVU
YUV格式中又分為YUV444,YUV422,YUV420
1.YUV 4:4:4取樣，每一個Y對應一組UV分量,一個YUV佔8+8+8 = 24bits 3個位元組。
2.YUV 4:2:2取樣，每兩個Y共用一組UV分量,一個YUV佔8+4+4 = 16bits 2個位元組。
3.YUV 4:2:0取樣，每四個Y共用一組UV分量,一個YUV佔8+2+2 = 12bits 1.5個位元組。
YUV420中又分為，YUV420SP與YUV420P
在camera相關案子得應用中有平台影響推流的問題待釐清，就順勢追了一下code
private final Timer timer = new Timer();
private final TimerTask tickTask = new TimerTask() {
public void run() {
VirtualCameraCapturer.this.tick();
}};
private void tick() {
// Log.d("CAM_AntiPushEngine", "VirtualCameraCapturer frame=" + frame + " buffersize=" + frame.getBuffer().getHeight());
capturerObserver.onFrameCaptured(frame);
}
其中frame由另一函式放張圖片來更新再透過tick作推送
try {
Log.d(TAG, "VirtualCameraCapturer...1");
inputStream = context.getAssets().open("clip_480x360_Format-0.yuv");
int size = 480 * 360 * 3 / 2;
byte[] data = new byte[size];
inputStream.read(data, 0, size);
Log.v("NV12","KH123");
VideoFrame.Buffer frameBuffer = new NV12Buffer(480, 360, 480, 360, ByteBuffer.wrap(data), new Runnable() {
//VideoFrame.Buffer frameBuffer = new NV21Buffer(data, 480, 360, new Runnable() {
@Override
public void run() {
Log.d("lhq", "NV21Buffer release");
}
});
Log.v("NV12","KH456");
long captureTimeNs = TimeUnit.MILLISECONDS.toNanos(SystemClock.elapsedRealtime());
frame = new VideoFrame(frameBuffer, 0, captureTimeNs);
Log.v(TAG, "VirtualCameraCapturer...2");
} catch (IOException e) {
e.printStackTrace();
}
由上述程式碼可看到 應用程式新增一個timer tick去定期將camera擷取到的影像frame推送到onFrameCaptured裡面。
此時我們追到另一個code base使用Find in path看誰會去呼叫onFrameCaptured函式。
在webrtc中的Camera1Session.javad查詢到
private void listenForTextureFrames() {
private void listenForBytebufferFrames() {
會使用到onFrameCaptured
在 listenForTextureFrames()中可在以下程式碼段前後擷取出raw data看其格式及圖片檢查是否正確
inal VideoFrame modifiedFrame = new VideoFrame(
CameraSession.createTextureBufferWithModifiedTransformMatrix(
(TextureBufferImpl) frame.getBuffer(),
/* mirror= */ info.facing == android.hardware.Camera.CameraInfo.CAMERA_FACING_FRONT,
/* rotation= */ 0),
/* rotation= */ getFrameOrientation(), frame.getTimestampNs());
Log.v(TAG, "Modified frame");

[Android]BitmapFactory.decodeResource在設定圖檔發生大小不一致的問題
最近在開發android media player的專輯封面圖檔
發現會有圖檔設定大小不符合預期的情形 如下面所述程式碼
mBitmap = getMirrorBitmap(BitmapFactory.decodeResource(getResources(), R.drawable.cluster_media_music_icon_albums_disable) , percent);
埋log發現不符合大小是該行程式碼所引起,因此特別去搜尋 找到網路上有些關文章討論跟我發生一樣狀況的文章
BitmapFactory.decodeResource之坑 ：https://www.itread01.com/content/1546283285.htmlBitmap resize api
public Bitmap getResizedBitmap(Bitmap bm, int newWidth, int newHeight) { int width = bm.getWidth(); int height = bm.getHeight(); float scaleWidth = ((float) newWidth) / width; float scaleHeight = ((float) newHeight) / height; // CREATE A MATRIX FOR THE MANIPULATION Matrix matrix = new Matrix(); // RESIZE THE BIT MAP matrix.postScale(scaleWidth, scaleHeight); // "RECREATE" THE NEW BITMAP Bitmap resizedBitmap = Bitmap.createBitmap( bm, 0, 0, width, height, matrix, false); //bm.recycle(); return resizedBitmap;}

[Android]Android BT avrcp framework層巡禮
爬了一整圈Android BT framework的sourcecode 看到這篇，有些坑也提到了就引用分享一下 :

接收intent註冊
IntentFilter filter2 = new IntentFilter();
private BroadcastReceiver mBTReceiver = new BroadcastReceiver() {
上層打通回控的程式
在media的page建立回控程式 我參考了網址:

看一下棒棒糖版本的回控 瞭解了 除了接收要註冊AVRCP相關的intent及Receiver外 傳送部分控件的建立必須先部屬BTAdapter 接著
