No, I have not tested it with vlc, so it would be great if you could do it.
If you got any error just try to capture the rtstp negotiation with ethereal
and
send it to me with the output error and I'll try to fix it.

The problem with the app_h324m and app_rtsp is that when asterisk
tries to get the best format for comunitating both channels it doesn't
use AMR so it behaves as if it were no audio and fails.
I think that the best way of solving it would be using the AMR codec
patch that Paul Bagyenda sent to the asterisk-dev list. At least
asterisk would now about the AMR codec and would let the call progress.

I think I wroke the mp4_save in one of the latest updates, I'll try to fix
it as soon as I can.
Anyway try running asterisk with -f -g options and get a backtrace output
from the core
dump and we could fix the dump on erroneous mp4 files.
