CameraX 視頻錄制凍結並生成空視頻文件

[英]CameraX video recording freezes and generates empty video file

問題描述

我使用以下兩種情況（預覽+視頻捕獲）使用 CameraX 實現了視頻錄制，如下所示：

@SuppressLint("RestrictedApi")
    @Override
    public android.view.View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        executor = Executors.newSingleThreadExecutor();
        android.view.View rootView = super.onCreateView(inflater, container, savedInstanceState);
        PreviewView previewView = rootView.findViewById(R.id.camera);
        ImageView capture = rootView.findViewById(R.id.capture);

        ListenableFuture<ProcessCameraProvider> cameraProviderFuture =
                ProcessCameraProvider.getInstance(getActivity());

        cameraProviderFuture.addListener(() -> {
            try {
                // Camera provider is now guaranteed to be available
                ProcessCameraProvider cameraProvider = cameraProviderFuture.get();

                // Set up the view finder use case to display camera preview
                Preview preview = new Preview.Builder().build();

                // Set up the capture use case to allow users to take photos
                videoCapture = new VideoCapture.Builder()
                        .setVideoFrameRate(30).setTargetAspectRatio(AspectRatio.RATIO_4_3)
                        .build();

                // Choose the camera by requiring a lens facing
                CameraSelector cameraSelector = new CameraSelector.Builder()
                        .requireLensFacing(CameraSelector.LENS_FACING_BACK)
                        .build();

                // Attach use cases to the camera with the same lifecycle owner
                Camera camera = cameraProvider.bindToLifecycle(
                        ((LifecycleOwner) this),
                        cameraSelector,
                        preview,
                        videoCapture);

                // Connect the preview use case to the previewView
                preview.setSurfaceProvider(
                        previewView.getSurfaceProvider());

                capture.setOnClickListener(onCaptureClick);

            } catch (InterruptedException | ExecutionException e) {
                // Currently no exceptions thrown. cameraProviderFuture.get()
                // shouldn't block since the listener is being called, so no need to
                // handle InterruptedException.
            }
        }, ContextCompat.getMainExecutor(getActivity()));

        return rootView;
    }

    private Boolean isRecording = false;

    private View.OnClickListener onCaptureClick = new View.OnClickListener() {
        @SuppressLint({"RestrictedApi", "MissingPermission"})
        @Override
        public void onClick(View view) {
            if(!isRecording){
                isRecording = true;
                SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyyMMddHHmmss", Locale.US);
                String timestamp = mDateFormat.format(new Date());
                File mediaFile = new File(GlobalConstants.TEMP_DIR(), "VID_" + timestamp + ".mp4");// File.createTempFile("IMG_", ".jpg", tempDir);
                VideoCapture.OutputFileOptions outputFileOptions = new VideoCapture.OutputFileOptions.Builder(mediaFile).build();
                videoCapture.startRecording(outputFileOptions, executor, new VideoCapture.OnVideoSavedCallback() {
                    @Override
                    public void onVideoSaved(@NonNull VideoCapture.OutputFileResults outputFileResults) {
                        Log.d(LOG_TAG, "videoSaved");
                    }

                    @Override
                    public void onError(int videoCaptureError, @NonNull String message, @Nullable Throwable cause) {
                        Log.d(LOG_TAG, "videoError");
                    }
                });
            } else videoCapture.stopRecording();
        }
    };

預覽用例工作正常，但在開始錄制時，在某些錄制會話上工作正常，但在其他錄制會話上，屏幕凍結並且在停止錄制時，成功調用onVideoSaved回調但生成的視頻文件為空。

這種行為是隨機的，因為有時會發生在第二次錄制中，有時我能夠成功執行 10 次以上的錄制。 這在帶有 Android 5 的三星上完美運行，但在帶有 Android 9 的三星 Tab Active2 上崩潰。

你可以使用這個庫，而不是做所有這些。 它將為您完成所有任務。

如何實施

Options options = Options.init()
                .setRequestCode(100)     
                .setCount(1)
                .setFrontfacing(false)
                .setSpanCount(1)
                .setMode(Options.Mode.Video)
                .setScreenOrientation(Options.SCREEN_ORIENTATION_PORTRAIT)    
                .setPath("/Chatverse Captures");
        Pix.start(this, options);

將此添加到您要錄制的位置，錄制時，您可以獲得這樣的文件路徑

將此粘貼到onActivityResult

if (requestCode == 100){
        if (resultCode == Activity.RESULT_OK && requestCode == 100) {
            String returnValue = data.getStringArrayListExtra(Pix.IMAGE_RESULTS).get(0);
            Toast.makeText(this,returnValue,Toast.LENGHT_SHORT).show();
        }
    }
