What is the EXCLUSIVE access mode in gst_mini_object_lock()

[Wim Taymans]

Hi,

It means the object is shared (like when a memory is added to 2 buffers).
When the object is locked exclusively more than 1 time, you can't write to
it (otherwise both holders of the exclusive lock would see each others
changes).
