Hi,

I'm new with OpenCV and i've got an issue.

i'm tring to run one of the tutorial that came with the "OpenCV-2.4.6-android-sdk", for this question lets say The "OpenCV Tutorial 3 - Camera Control".

I have 2 devices, Galaxy S3 and Galaxy S4.

The tutorial works properly on Galaxy s3, but on Galaxy s4 the video get stuck(black screen)

In both devices i installed the latest OpenCV Manager.

Thanks for helping

As far as I know the libraries of opencv are not compatible with the galaxy s4 yet. Most likely samsung has done some custom stuff internally (regarding camera api) that does not comply to the android standard. The same also happens on other devices. (in case you use the google s4 with android 4.3 it wouldnt work anyways since there are no libs for android 4.3 yet)

2 things: 1. Is it known when or whether adjustment will be made between the new OpenCV libraries and Galaxy s4? 2. Is there an alternative for how can i work with openCV or another image processing library with Galaxy s4 and S3?

Thank!

  1. I dont know. Sorry.
  2. You can try to use the camera through the android API (not via NativeCameraView or JavaCameraView) Maybe this helps: http://stackoverflow.com/questions/15959552/unable-to-use-both-cameras-of-evo-4g-using-opencv4android/

But can i use an image processing function with this API?

Here is the issue tracker: http://code.opencv.org/issues/3113

In the link I provided, he creates a mat, so you should be able to use image processing on it
