n.eko (m1k1o fork)

This app uses Web RTC to stream a desktop inside of a docker container. This is fork of https://github.com/nurdism/neko.

Differences to original repository.

New Features

• Clipboard button with text area - for browsers, that don't support clipboard syncing (FireFox, what a shame...) or for HTTP.
• Keyboard modifier state synchronization (Num Lock, Caps Lock, Scroll Lock) for each hosting.
• Added chromium ungoogled (with h265 support) an kept up to date by @whalehub.
• Added Picture in Picture button (only for watching screen, controlling not possible).
• Added RTMP broadcast. Enables broadcasting neko screen to local RTMP server, YouTube or Twitch.
• Stereo sound (works properly only in Firefox host).
• Added limited support for some mobile browsers with playsinline attribute.
• Added VIDEO_BITRATE and AUDIO_BITRATE in kbit/s to control stream quality (in collaboration with @mbattista).
• Added MAX_FPS, where you can specify max WebRTC frame rate. When set to 0, frame rate won't be capped and you can enjoy your real 60fps experience. Originally, it was constant at 25fps.

Bugs

• Fixed minor gst pipeline bug.
• Locked screen only for users, admins can still join.
• Fixed h264 pipelines bugs (by @mbattista).
• Fixed sessions manager thread safety by adding mutexes (caused panic in rare edge cases).
• Now when user gets kicked, he won't join as a ghost user again but will be logged out.
• iOS compatibility! Fixed really strange CSS bug, which prevented iOS from loading the video.

Misc

• Custom docker workflow.
• Based on debian buster instead of stretch.
• Custom avatars without any 3rd party depenency.
• Ignore duplicate notify bars.
• No pointer events for notify bars.
• Disable debug mode by default.
• Remove HTML tags from user name.
• Upgraded pion/webrtc to v3 (by @mbattista).

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.
