USB Video

[CastleWorks]

Hi All,

Has anyone had any experience with reading streaming video from one of the USB ports on the A13?

I am looking for code that will read either MPEG or YUV steaming video and either display it on the VGA port or even better deliver it to my WiFi where I can view it on my mobile device.

Thanks

Do you mean a video from a some kind of V4L video source, for example from a webcam or an analog camera (via a USB capture device}?

Yes this is from camera made by Leopard Imaging similar to a web camera. It is a UVC compliant USB 2.0 camera.

You can try what is described in the above topic.

What works for sure but is not MPEG or YUV is MJPEG streamer.

Thanks Gerrit,

Actually looking back at the camera specs I was mistaken, the format is MJPEG so this may work very well. I will give it a try.

Gerrit,

The MJPEG streamer you recommended is for the Rasberry Pi....I am VERY new to this stuff and very much a rookie, will the same code run on the A13 and the build instructions the same.
Thanks
