Steps to reproduce
val videoCapture = VideoCapture(videoPath)
try {
while (videoCapture.isOpened){
val mat = Mat()
videoCapture.grab()
val isRetrieved = videoCapture.retrieve(mat)
if(isRetrieved){
val src = Bitmap.createBitmap(mat.cols(), mat.rows(), Bitmap.Config.ARGB_8888)
Utils.matToBitmap(mat, src)
//use src Bitmap
}
}
}catch (e:Exception){
//catch exception
Log.d("TAG_ERROR", "exception! : $e")
}finally {
videoCapture.release()
}
or
val videoCapture = VideoCapture(videoPath)
try {
while (videoCapture.isOpened){
val mat = Mat()
if(videoCapture.read(mat)){
val src = Bitmap.createBitmap(mat.cols(), mat.rows(), Bitmap.Config.ARGB_8888)
Utils.matToBitmap(mat, src)
//use src Bitmap
}
}
}catch (e:Exception){
//catch exception
Log.d("TAG_ERROR", "exception! : $e")
}finally {
videoCapture.release()
}
but both code not working same.
Couldn't catch exception .
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues,
forum.opencv.org, Stack Overflow, etc and have not found solution - I updated to latest OpenCV version and the issue is still there
- There is reproducer code and related data files: videos, images, onnx, etc
