Options

Example: &preferchannel=3

Value	Description
1-8	Preferred audio channel number (C1-C8)

Details

When a guest joins a room where the director has &autochannels enabled, this parameter requests that the guest be assigned to a specific audio channel.

How it works

1. Guest adds &preferchannel=N to their invite link (where N is 1-8)

2. When they connect, this preference is sent to the director

3. If the director has &autochannels enabled and the requested channel is in the allowed list, the guest is assigned to that channel

4. If the channel is not allowed (e.g., director excluded it), normal auto-assignment is used instead

Use case

This is useful when you want the same guest to always end up on the same audio channel across multiple sessions, making post-production editing easier.

Example

Guest link requesting channel 3:

https://vdo.ninja/?room=myroom&preferchannel=3

Director link that allows channel 3:

https://vdo.ninja/?director=myroom&autochannels=1,2,3,5,6,7,8
