I don't know. But the mp4_save function (in app_mp4) using libmp4v2 do
create an mp4 with a-law in it. Dump from mp4info:

mp4info version 1.6
save.mp4:
Track   Type    Info
1       audio   G.711 aLaw, 25.980 secs, 64 kbps, 8000 Hz
2       hint    Payload PCMA for track 1

So that it is (technically) possible is evident. Of course, I can't find
anything that can play it :) But the mp4_play function (of app_mp4) needs
this specific setup :(
