LinuxQuestions.org - [SOLVED] No audio recorded in ffmpeg

No audio recorded in ffmpeg

Hello all.

I am feeding the following to ffmpeg:

Code:

ffmpeg -f x11grab -r 30 -s 1366x768 -i :0 -f alsa -ac 2 -i hw:1,0 -vcodec libx264 -crf 0 -preset ultrafast -acodec libvorbis -ab 192k ryVideo1.mkv

The video is working very well! However, despite my efforts, I have been unable to record any audio. I have also tried 'plughw:1,0'. My guess is that maybe I am recording the desktop audio instead of the audio from my built-in microphone.

My laptop is an HP dv6-6135dx. Here is the spec page:
http://h10025.www1.hp.com/ewfrf/wc/d...roduct=5118737

I have checked all 'alsamixer' settings, and have put them at a variety of levels. Here is some pertinent output:

Code:

{root@slack64}:~$ aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: Generic [HD-Audio Generic], device 3: HDMI 0 [HDMI 0]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

card 1: Generic_1 [HD-Audio Generic], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

{root@slack64}:~$ arecord -l

**** List of CAPTURE Hardware Devices ****

card 1: Generic_1 [HD-Audio Generic], device 0: 92HD81B1X5 Analog [92HD81B1X5 Analog]

  Subdevices: 1/1

  Subdevice #0: subdevice #0

I also put the following '.asoundrc' into the home and root folder:

Code:

pcm.!default {

  type hw

  card 1

}



ctl.!default {

  type hw

  card 1

}

Help! I'd really like to make some videos (with audio)!

;-)

Taking a bit of a shot in the dark, but there should be a device named 'CAPTURE' somewhere in alsamixer, or kmix, etc. On mine it's the second one from alsamixer on the f4 set. To enable it, you have to press space.

Not sure what else it could be really.

Sometimes it's the simple things that we as geniuses miss. *wink*

Hi @ryanpcmcquen

This solution was for an older version of Slackware and might not apply to a newer version. Can you open up a new topic with your symptoms and what you've tried to do to fix it? Then we can try and help out with your current version of Slackware.
