How to read a avi file from Android Opencv?

[mw18888]

I like to open an video file during the test phase.

Can we modify the

package org.opencv.highgui;

public class VideoCapture {

and add

public VideoCapture(String fileName)
{
nativeObj = n_VideoCapture(fileName);

return;
}

Thank.

Sorry, but no. OpenCV doesn't support video capturing on Android. This feature will be implemented in next major release. During the test phase we split video into separate images (http://stackoverflow.com/questions/3917601/ffmpeg-split-avi-into-frames-with-known-frame-rate) and read them with imread.

We have a build system for making ffmpeg binaries on Android that could be plugged into a Video->openCV workflow

Hi!

No guarantees, but we are going to try to enable Video IO support for Android 3+ in 2.4.3 release, early September. In the meantime you can use default Android Java API.

Hi Nathan, i have tried to build your project but i have failed.
Make says some files are missing, for example:

Makefile:2: config.mak: No such file or directory
Makefile:47: /common.mak: No such file or directory
Makefile:88: /libavutil/Makefile: No such file or directory

Don't know what is wrong, I have followed your README instructions.
I am running ubuntu 12.04.

Any Help?

It's still not yet implemented.

Is basic file I/O supported, e.g. to load a parameter file or classifier?

thanks,

Sure,

e.g. you can load a cascade classifier with a code like this:

new CascadeClassifier(mCascadeFile.getAbsolutePath());
