[gst-devel] filesink content -> outputing in a file

[thiagoss]

I suppose you're finishing your application by pressing ctrl-c, I don't know
if wavenc cares about it, but this way you get no eos (if wavenc cares about
it to finish the file, this makes a difference). You might want to set
num-buffers property of audiotestsrc and listen for EOS messages from the
bus and quit the mainloop when it happens.

Btw, what was the problem with gst-launch -e ?
