4 years ago Does the camera work with other software?
Try using the YUYV format.
And show me the log of this command: mplayer -v -tv driver=v4l2:device=/dev/video0:outfmt=mjpg tv://

4 years ago I tested the camera under windows10 and it works. Camera is OK. i tried mjpg-streamer-experimental under linux server and it doesn't work too.

4 years ago I did not install any driver. I thought it was part of the kernel. That's probably the problem... But I haven't found it anywhere...

As far as I understand, Linux does not support this camera and tries to use the default driver (uvc). It seems that a special module is needed for this camera: https://github.com/allwinner-zh/linux-3.4-sunxi/blob/master/drivers/media/video/sunxi-vfe/device/ov2710.c This driver is written for an old version of the kernel, for some fork. Perhaps it can be adapted for the new kernel, but unfortunately I can't help you with this.

4 years ago I agree with you. I was looking for a small camera (usb module) with high resolution and fast FPS for linux. I don't need a microphone. Can you please recommend one? Thank you for your time.

4 years ago The only camera I can advise you is Logitech HD Webcam C930e. I use it and it works fine in Linux. I'm sorry, but I haven't encountered the camera modules you require.
I think you can write to the LKML mailing list with a message that the UVC driver doesn't work with your camera, and give a link to the module. Perhaps kernel hackers will either fix the module or advise you on how to make your camera work.
Hello, i can't start the ov2710 camera. What am I doing wrong ? Thank you.
