Web camera Logitech and Linux

Question

I have Logitech C310 camera with the declared characteristics of 720p 30fps.

If you connect the camera to windows, the recording is fully consistent with the stated 720p 30fps - the picture is clear.

The challenge is to connect the same camera to OrangePI (server Armbian) and to save video files on it.

The camera appears as /dev/video0.

sudo ffmpeg -f v4l2 -s 1280x720 -i /dev/video0 output.wmv

As a result, I get a crumbly picture with a frequency of 5 fps.

Maybe I'm using ffmpeg incorrectly? Please help me who has experience with Web cameras on Linux ... Thanks in advance.

USB-camera configuration:

v4l2-ctl --all --device=/dev/video0

Answer 1

I run a webcam on a Raspberry Pi Raspbian, this is the code i use to capture video (this runs at 25 fps fine):

            var args = [
            "-i",
            "/dev/video0",
            "-r",
            "25",
            "-qscale",
            "1",
            "out.avi"
        ];

        var process = spawn("avconv", args);

"avconv" is the same as ffmpeg pretty much, i don't know the specifics of the difference but this may work for you. Very basic example, this was just to test the camera. -r specify fps, -qscale is quality (there are alternative commands).
