I am recording speech from /dev/dsp1 - the level is good, the a/d is good, the
first 10 seconds sound fine. then it gets garbled. it may be mplayer. on one
test mp crashed.
Here is what has worked best for me. hoping someone can suggest better.
Almost any v4l device that I'm aware of delivers uncompressed, PCM
audio.
in case it matters, it may not be a v4l device. it is a lxr -> usb adapter:
http://www.everythingusb.com/soundtech_lightsnake_usb_instrument_cable.html
So, please try (not in any particular order)
-x v4l,v4l
Audio: no sound
-x v4l,oss
[transcode] warning: /usr/lib/transcode/import_oss.so: cannot open shared object
file: No such file or directory
doh! I'll get on that.
-x v4l,raw
Audio: no sound
Below are the logs from v4l and raw.
