[gst-devel] Recordind from alsasrc to filesink

[Guilherme]

Mates, just for reference

running

gst-launch audiotestsrc ! audioconvert ! wavenc ! filesink 
location=/home/guilherme/Desktop/test.wav

creates a test.wav file of 18 minutes, no matter when I stop recording 
and also it generates a horrible cracking sound...

;o/

Looking for help with waveenc I cant find much information as you can see:

http://gstreamer.freedesktop.org/data/doc/gstreamer/0.10.0/gst-plugins-good-plugins/html/gst-plugins-good-plugins-plugin-wavenc.html

Tks!
