I think the bin is the element parents. But I wonder if I can get an element by name before put it into a bin. Can I do it ?

If it's not inside anything (bin, pipeline, etc.), then you can't do that - either you have a direct reference to the object (in which case you could just use it), or you don't - in which case the object should have been freed, because its refcount will be zero. There's no global registry of currently-instantiated-gstreamer-elements in which to look something up by name. Mike |
