Tells the director which slot the guest should prefer to be in
Sender-Side Option! (&push, &room)
Example: &slot=4
0
Exclude this guest from the slot system
(integer value)
The slot number the guest should be assigned to
&slot=N is a guest side property (sender side). It tells the director (Mixer App / &slotmode) which slot the guest should prefer to be in, if slots are being auto-assigned. If the desired slot is already taken, then that guest will then not be assigned a slot. If the guest was assigned a slot by the director, refreshing will keep the assigned slot, and the URL-specified slot preference will be ignored.
&slot=0Using &slot=0 explicitly excludes the guest from the slot system entirely. This is useful for:
Instructors or hosts who should join the room but not consume a student slot
Musicians or special guests who use fixed stream IDs instead of slot-based layouts
Control room operators who need to monitor but not appear in slot-based scenes
Example: https://vdo.ninja/?room=classroom&slot=0&push=Instructor1
This guest will join the room and be visible in the director's control panel, but will not be assigned any slot number and won't appear in &viewslot scene links.
If looking to set the guest order for the auto-mixer's layout, the &order parameter is generally intended for that purpose. You can set the order as a director dynamically using the Mix Order button in the guest's control box.
