• Stereo sound (works properly only in Firefox host).
• Added limited support for some mobile browsers with playsinline attribute.

Bugs

• Locked screen only for users, admins can still join.
• Fixed h264 pipelines bugs (by @mbattista).

Misc

Getting started & FAQ

Use following docker images:

• m1k1o/neko:latest - for Firefox.
• m1k1o/neko:chromium - for Chromium Ungoogled (needs --cap-add=SYS_ADMIN).
• m1k1o/neko:base - for custom base.

Networking:

• If you want to use n.eko in external network, you can omit NEKO_NAT1TO1. It will automatically get your Public IP.
• If you want to use n.eko in internal network, set NEKO_NAT1TO1 to your local IP address (e.g. NEKO_NAT1TO1: 192.168.1.20)-

Why so many ports?

• WebRTC needs UDP ports for each channel it creates towards users.
• Every user will need 2 UDP ports (for getting audio/video and sending mouse positions).
• You can freely limit number of UDP ports. But you can't map them to diferent ports.
  • This WONT work: 32000-32100:52000-52100/udp
• You can change API port (8080).
  • This WILL work: 3000:8080

Behind reverse proxy?

Accounts:

• There are no accounts, display name (a.k.a. username) can be freely chosen. Only paword needs to match. Depeding on which password matches, visitor gets its privilege:
  • Anyone, who enters with NEKO_PASSWORD will be user.
  • Anyone, who enters with NEKO_PASSWORD_ADMIN will be admin.

Screen size

• Only admins can change screen size.
• You can set default screen size, but this size MUST be one from list, that your server supports.
• You will get this list in frontend, where you can choose from.
