I'm attempting to use easycap to record from my camcorder but I'm having a slight problem. Using their test script I'm able to get audio and video. I've noticed that in the script on line 159 it makes a call to "DEV_ADUIO", which is reported as being "plughw:2,0".

Exactly what is this device? Is it located in /dev/ somewhere?

I've done ls /dev/ and I can't find anything that would suggest an audio device

Run the command (in the terminal)

aplay -l

The output looks like

**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC262 Analog [ALC262 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

The device for this is plughw:0,0. The two zeros come from the device 0 and Subdevice #0.

  • The problem with that is when I try to put plughw:2,0 (my audio device) into something like ffmpeg. I just get an error – hellocatfood Jan 17 '11 at 23:20

    Oh, these are in /dev/snd/ – user4124 Jan 18 '11 at 14:44

    doesn't the 0:0 come from card 0 and device 0 ? – rewolf Nov 9 '13 at 21:44
