Configuration

Environment variables

NEKO_SCREEN:

  - e.g. '1920x1080@30'
NEKO_PASSWORD:
  - Password for the user login
  - e.g. 'user_password'
NEKO_PASSWORD_ADMIN
  - Password for the admin login
  - e.g. 'admin_password'
NEKO_EPR:
  - For WebRTC needed range of ports
  - e.g. 52000-52100
NEKO_VP8:
  - If vp8 should be used as video encoder for the stream (default encoder)
  - e.g. 'true'
NEKO_VP9:
  - If vp9 should be used as video encoder for the stream (Parameter not optimized yet)
  - e.g. 'false'
NEKO_H264:
  - If h264 should be used as video encoder for the stream (second best option)
  - e.g. 'false'
NEKO_VIDEO_BITRATE:
  - Bitrate of the video stream in kb/s
  - e.g. 3500
NEKO_VIDEO:
  - Makes it possible to create custom gstreamer pipelines. With this you could find the best quality for your CPU
  - Installed are gstreamer1.0-plugins-base /  gstreamer1.0-plugins-good /  gstreamer1.0-plugins-bad /  gstreamer1.0-plugins-ugly
  - e.g. ' ximagesrc display-name=%s show-pointer=true use-damage=false ! video/x-raw,framerate=30/1 ! videoconvert ! queue ! video/x-raw,format=NV12 ! x264enc threads=4 bitrate=3500 key-int-max=60 vbv-buf-capacity=4000 byte-stream=true tune=zerolatency speed-preset=veryfast ! video/x-h264,stream-format=byte-stream '
NEKO_MAX_FPS:
  - The resulting stream frames per seconds should be capped (0 for uncapped)
  - e.g. 0
NEKO_OPUS:
  - If opus should be used as audio encoder for the stream (default encoder)
  - e.g. 'true'
NEKO_G722:
  - If g722 should be used as audio encoder for the stream
  - e.g. 'false'
NEKO_PCMU:
  - If pcmu should be used as audio encoder for the stream
  - e.g. 'false'
NEKO_PCMA:
  - If pcma should be used as audio encoder for the stream
  - e.g. 'false'
NEKO_AUDIO_BITRATE:
  - Bitrate of the audio stream in kb/s
  - e.g. 196
NEKO_CERT:
  - Path to the SSL-Certificate
  - e.g. '/certs/cert.pem'
NEKO_KEY:
  - Path to the SSL-Certificate private key
  - e.g. '/certs/key.pem'
NEKO_ICELITE:
  - Use the ice lite protocol
  - e.g. false
NEKO_ICESERVER:
  - Describes a single STUN and TURN server that can be used by the ICEAgent to establish a connection with a peer (simple usage for server without authentication)
  - e.g. 'stun:stun.l.google.com:19302'
NEKO_ICESERVERS:
  - Describes multiple STUN and TURN server that can be used by the ICEAgent to establish a connection with a peer
  - e.g. '[{"urls": ["turn:turn.example.com:19302", "stun:stun.example.com:19302"], "username": "name", "credential": "password"}, {"urls": ["stun:stun.example2.com:19302"]}]'
