VideoCapture not working in opencv android

I'm trying to use VideoCapture() in an android application. The app makes a JNI call to the cpp file which has the videocapture() call and passes it a video path.

  • I have provided the storage read and write permissions.
  • The path is also in correct format like (/storage/emulated/0/filename.avi)
  • The video file that I put into my device is first encoded as mjpeg and then as avi using ffmpeg on my PC.

Still I get false result when I check VideoCapture.isopened().

Any suggestions to fix this issue?
