[Asterisk-video] can't hear amr audio

[Sergio Garcia Murillo]

Hi Klaus and Andrew,

I've just taken a quick look at the code, but I think that the code was 
there to be able to choose between the different codecs offered (without 
transcoding)
Now that we have support for amr in asterisk perhaps could be changed 
for something like ast_get_best_ codec or ast_codec_choose.

BR
Sergio
