Query about gst_bin_remove

[Yogesh Tyagi]

Yes I tested it and it returns NULL. I wanted to know the reason for
this.In my code when gst_pad_get_negotiated_caps() retuens NULL, I remove
the source pad and add new pad again. I don't want to do that. Is it
possible for source pad to retain old caps somehow?

Thanks,
Yogesh
