This creates a virtual device that you can use to record things from what I understood of it, didn't test it so I can't say for sure. Slave.pcm 'tee:default,'/tmp/out.raw',raw' You can also create a device so you can use it for capturing things. Post added at 06:12 PM CDT - Previous post was at 06:04 PM CDT.

Usually that means that input file is truncated and/or corrupted.Ĭrw-rw-+ 1 root audio 116, 7 10:27 controlC0 /dev/snd/pcmC0D0p' Soundcard does not support 16 bit sample format Me ~ 23:12:52$ sudo /home/me/bin/ffmpeg -f oss -i /dev/snd/hwC0D0 tmp.wav dev/snd/hwC0D0: Error while opening file I believe this to be related to the format option passes to ffmpeg -f cd or oss etc. Sudo gives me a different, but not very descriptive error.

I think my earlier problem using ffmpeg is related to file permissions as the devices in /dev/snd belong to root and the audio group. I thought that could be a nice little project to better acquaint myself with this stuff.ĭrwxr-xr-x. I wish I could find the link again, but there was a third alternative which required writing a bit of C code. Unfortunately this only records the microphone input and not everything else going through my sound server. Parec -format=s16le -rate=44100 -channels=2 sample.raw I found another alternative which uses parec. I tried pointing ffmpeg to a few of them, but it resulted in errors thus: /dev/snd/hwC0D0: no such file or directory I think these are in a separate directory /dev/snd however the content of this directory is not clear which device is the appropriate one.

I thought something likeĬould work, but I don't have a /dev/dsp. I believe that the system is using the PulseAudio sound server. I'm running F12 x86_64 on a Dell inspiron laptop.

This is going to display my woeful ignorance of Linux audio systems. The audio is the important for me for now. I'm not worried about capturing video yet. This is for a legitimate reason if anyone is worried I often have long conference calls on skype (an another voip collaborative tool called EVO), and a recording would be a nice way to keep minutes and participate in the working meeting. The most useful purpose is to record conversations on skype ( and other applications). I basically want to record audio streams. I didn't find it specifically in this forum already. I'm sorry if this has been covered before.
