[Duchassin Frederic]

My source is a "udpsrc" so I think it's not possible to use Bufferlist.

render_list() will only be called if upstream actually sends a buffer
list, which very few plugins do. Are you sure that's happening in your
case? Some rtp payloaders do and render_list() is used in udpsink for
that reason.
