If we don't have h264 support, why should we enable aac then? Also there is
https://github.com/knik0/faac which is LGPL. Looks like it ffmpeg has support
for that.

Without --disable-decoder="mpeg4,h263,h264,hevc,vc1" the paranoia check
triggers! I will remove --disable-parsers and --disable-muxers stuff.
