Motion-JPEG decoder/encoder

There is a camserv in uClinux-dist.

You need to modify shared library usage in it.

The camserv should support a http interface, so you don't need boa.

Are you using USB webcam? I don't think the USB on DE2 is fast enough to support video in.

You should use composite video input or camera module through 40pins headers (Terasic has it).

I haven't tried video input on DE2 yet. I will try them later.

PS. I checked USB wlan on DE2, I think it is the isp1362 hcd driver's problem.

hi, hippo

Thank you very much for your reply.

I used DE2&#39;s camera module through 40pins headers.

I will use wireless to transmission images from DE2 board to PC.

Is fast enough?

hi, hippo

Thank you very much for your reply again.

I&#39;m new hand for NiosII uClinux.

I used DE2&#39;s camera module through 40 pins headers.

The webcam&#39;s data is RGB format.

I will transmit images form DE2 board to PC, then process images, so I need compress and decompress it.(JPEG Format)

My problem is how to transform RGB format become JPEG format.

Does uClinux-dist can do it?

I found the camserv needs shared lib, and nios2 cannot support it.

Please use "vidcat" and "w3camd". I had built them successfully.

The nios2 patch is updated to ver 29.

Yes. You can study the codes in user/w3cam .

You will still need a video input driver. I will help you when I have time.
