Weren't we talking about the *server* pipeline with the appsrc? I was<br>
talking about that, and I assume the log messages were in reference to<br>
that as it seems unlikely that rtpmp4gdepay is creating invalid aac<br>
caps.<br>
<br>
On the receiver side, there should be no need for a capsfilter between<br>
aacparse and avdec_aac, they should figure out the format between<br>
themselves automatically.<br>
<br>
Cheers<br>
