B4J Question webcam stream in a window...

[Pietro Pancino]

Hi Everyone !

I need to display continously 2 different Webcam capture on the screen, is there any library to do that.
I did it with FLASH AIR, but I don't know if it's possible in B4J?
I try to use the webcam-capture library but its seems it's only possible to make image capture, so ...

If you can get a mjpeg stream from the cameras then you will be to able to show them with the mjpeg decoder class.

Seems to be possible with FFmpeg: https://trac.ffmpeg.org/wiki/StreamingGuide

Thanks Erel!

I'll look at that....

You can use OpenCV (if it accepts 2 webcams I don't know - I haven't tested)
See my demo here:

And it might be possible also with my B4JVlcj-wrapper:

However, check the documentation first and if it is possible, you might be able to expose the methods needed using JavaObject.

Edit: it is possible with B4JVlcj - see next post below.

With my B4JVlcj-wrapper you can embed and show your WebCam in B4J. I am pretty sure you can add a second WebCam in another form too.
I don't have a second WebCam but in this little project shown in below video, I added a 2nd instance of VLC which plays a video and both are working fine at the same time.

Hey Pietro - did you find any solution? Which one worked best for you?

Thanks
