Revision history [back]

Hi,

My aim is to load two video files, grabbing the frames from each file and creating a single frame.

I have understood I can use VideoCapture java class to load files and use Mat class to work on individual frames.

I have two AVI files stored at /storage/emulated/0/Download/received_files/<file>.avi. However VideoCapture is unable to open the files.

VideoCapture vc1 = new VideoCapture();
 VideoCapture vc2 = new VideoCapture();

 if (!vc1.open(video1)) {
    Log.e(TAG, "Could not open the video file1");
 } else {
    Log.i(TAG, "Video1 loaded");
 }

 if (!vc2.open(video1)) {
    Log.e(TAG, "Could not open the video file1");
 } else {
    Log.i(TAG, "Video2 loaded");
 }

It always pronts "Could not open ..." message. I have tested the file paths using File.exists and it returns true. What am I missing here?

I am using OpenCV 3.2.0 for Android and Android lollipop.

My Android setup is done properly and I can view the camera in JavaCameraView.
