I have an EEE PC 701 and want to record video using the built-in webcam. I have installed Lubuntu 14.10. I already have installed avconv and I want to use avconv.

If you want to use avconv

Find video device

 ls /dev/video*

suppose video0

2- Find audio device

 arecord -l

suppose output like this

 card 1: U0x46d0x8ad [USB Device 0x46d:0x8ad],........

Then the audio device would be:

plughw:U0x46d0x8ad,0

Capture video and audio:

avconv -f video4linux2 -r 25 -i /dev/video0 -f alsa -i plughw:U0x46d0x8ad,0 -ar 
22050 -ab 64k -strict experimental -acodec aac -vcodec mpeg4 -y webcam.mp4

If you want to try some GUI apps:

1.Camorama Webcam Viewer

To install it:

sudo apt-get install camorama

2.GTK+ base UVC Viewer

Install GUVC Viewer

sudo apt-get install guvcview

  • `avconv -f video4linux2 -r 25 -i /dev/video0 -f alsa -i plughw:Intel,0 -ar 22050 -ab 64k -strict experimental -acodec aac -vcodec mpeg4 -y webcam.mp4` – Maythux May 12 '15 at 10:35
  • I get the error: `[alsa @ 0x976c3a0] cannot open audio device plughw:Intel,0 (No such device) plughw:Intel,0: Input/output error` – wb9688 May 12 '15 at 10:47
