Weren't we talking about the *server* pipeline with the appsrc? I was
talking about that, and I assume the log messages were in reference to
that as it seems unlikely that rtpmp4gdepay is creating invalid aac

On the receiver side, there should be no need for a capsfilter between
aacparse and avdec_aac, they should figure out the format between
themselves automatically.
