Hi,
Since it works fine cant you patch it up and propose to add on gstreamer?
Then we all can use it and make it work even better.
You used libsrtp to implement this encoder / decoder ?

"Se você se perder na selva africana, não precisa se desesperar. Basta
sentar em uma pedra e começar a instalar GNU/Linux em seu laptop. Em menos
de 5 minutos aparecerá alguém pra discordar de sua escolha de distribuição,
do particionamento, do gerenciador de janelas, do ambiente de desktop, do
editor de textos..."
