Comment (by Cigaes):

 This is a bug in amix:

 {{{
                         /* unclosed input with not enough samples */
                         return 0;
 }}}

 Returning 0 without filtering samples is not acceptable. Fixing it with
 {{{AVERROR(EAGAIN)}}} allows to make some progress, but freezes later.

 I will try to look into it if time permit, but I consider amix to be
 mostly unsupported.
