Android Question barcode scanning from a video stream or file

[peacemaker]

HI, All

Possible ? If there is a remote camera that send the video stream to a smartphone... Or maybe send video files to analyze...
Any sample ?

If you can extract images from the video then you can sample the video and pass the images to: Barcode reader based on Google Play Services Vision

Thanks, Erel, but then the question is how to extract frame images from video files or stream...
And your reply now means that no ready way to work with stream ?

Hi,

Try to mix this:

and this:

I think with this information you can do it.

It depends on the type of stream. It is a mjpeg stream then you can use mjpeg decoder class to extract frames.

If you are interested in extracting frames from a video (and more), then my ffmpeg-encoder can do that easily.
If you are interested, just send me a PM.
