set srtp-key to udpsrc caps

[Alicia Romero]

Thanks for your answer. You were right, but if I use:
const guint8 key[] = { 0, 1, 2, 3, 4, 5, 6, 7, ... };
buf = gst_buffer_new_wrapped (g_memdup (key, sizeof (key)), sizeof(key));

I get:
srtp-key=(buffer)000102030405060708090001020304050607080900010203040506070809

Thanks!!!
