Hi there,

I'm tying to to detect motion using opencv(2.4.8) camera preview on android and record video camera view. Is videowriter API not functional latest opencv on android now? If not now, is there any plan to support that API later?

Thanks

the videoWriter is missing in the java api
additionally, there's no ffmpeg backend on android

so, in short: no, currently you can't write or read video files on android using opencv.

And to answer to your plans to support his API later, it seems developers are focussing on the 3.0 release for the moment. So won't be expecting this stuff in the near future :)

3.0 is due like end of next month, and it's still not in there.

Thank you for reply, I have more question, "currently you can't write or read video files on android using opencv" which means that I can't write or read video during processing the motion detection using opencv? If I use android native api for video record, can I implement recording + simultaneous motion detection using opencv on android?

oh, yes you might have a chance with jni / ndk. ( i just don't know much about it )

well, if you get something working, please report back, to help others here ( it seems to be quite a common problem )
