Hi All,
I'm banging my head against a wall trying to figure this out. I'm running on a Ubuntu Linaro ARM 71.
Code:
mike@linaro-gnome:~$ uname -a
Linux linaro-gnome 3.4.0-g58e4014-00018-gfd56be5 #1 SMP PREEMPT Thu Oct 9 13:01:53 IST 2014 armv7l armv7l armv7l GNU/Linux
I'm having a heck of a time trying to get ffmpeg to take video in from a webcam. This should be straight forward and it doesn't seem to be.
Code:
mike@linaro-gnome:~$ sudo ffmpeg -f video4linux2 -s 320x240 -i /dev/usbdev1.1 out.mpg

[video4linux2,v4l2 @ 0xe9f450] ioctl(VIDIOC_QUERYCAP): Inappropriate ioctl for device
/dev/usbdev1.1: Inappropriate ioctl for device
The usbdev1.X changes every time I unplug the webcam in. I'm not sure how to get past the above error. I've tried creating a video0 device. The video device never worked and is removed on boot. Do I need a different kernel?
Code:
sudo mknod /dev/video0 c 81 0
sudo chmod 666 /dev/video0
sudo chgrp video /dev/video0
sudo ln -s /dev/video0 /dev/video
