How to remove a source of a Adder while playing?

[Lucas Alberto]

Hi Tim,
Thanks for the answer.
Now I can add new sources to a Adder element, it works just as simple
as you wrote.

But I got another problem when I tried to dinamically connect live
sources (rtmpsrc) to a Liveadder element. It's dropping all the new
source's buffers because they has late timestamps.
Do you or another gstreamer master knows how to timestamp the input
buffers to the running time?

I can't pause the pipeline because the audio processing has to be gapless.
