Ubuntu – Compiling AVLD on 11.04

11.04compilingkernel-modulesvideo

I'm trying to install AVLD 1.4 on Natty.

I've unpacked the files, but when I compile them with make, it fails:

make -C /lib/modules/2.6.38-8-generic-pae/build M=/home/jmendeth/Downloads/avld_0.1.4 modules
make[1]: entering «/usr/src/linux-headers-2.6.38-8-generic-pae»
  CC [M]  /home/jmendeth/Downloads/avld_0.1.4/video_device.o
/home/jmendeth/Downloads/avld_0.1.4/video_device.c:23:28: fatal error: linux/videodev.h: No such file or directory
compilation terminated.
make[2]: *** [/home/jmendeth/Downloads/avld_0.1.4/video_device.o] Error 1
make[1]: *** [_module_/home/jmendeth/Downloads/avld_0.1.4] Error 2
make[1]: leaving «/usr/src/linux-headers-2.6.38-8-generic-pae»
make: *** [all] Error 2

I have tried to install libv4l-0 and libv4l-dev, but still the same error.
If I replace linux/videodev.h with linux/videodev2.h on the file, a lot of errors pop out.

Any ideas?

AVLD doesn't appear to be maintained anymore.

A similar video loopback package exists in the repositories which you can install - its called v4l2loopback-source.

Auto Install

First from a terminal, drop to a root shell

sudo su

If you havent installed kernel modules before with module-assistant run the following from a terminal

apt-get install module-assistant
m-a prepare
m-a update

Finally - download and install v4l2loopback

m-a a-i v4l2loopback
exit

Manual Install

Download the package - once installed it can be found in /usr/src/v4l2loopback.tar.bz2

Copy the package to, for example your ~/Downloads folder compile and install

cd ~/Downloads
tar -xvf v4l2loopback.tar.bz2
cd modules/v4l2loopback
make
sudo make install
sudo modprobe v4l2loopback

This will create a /dev/video0 or /dev/video1 (etc) device.
