OK, I did some more research on these issues.

placing the new stream index before the test appears to fix the problem.
e = avcodec_encode_audio2(c, &pkt, frame, &got_packet);
pkt.stream_index = st->index;
if (!got_packet)
return;

This error appears to have to do with mp4 not allowing variable frame rates.
I'm assuming that if I increment PTS to an exact multiple of the fixed frame
length, it will fix the problem. I'll try that.
