Dependencies

Python

NumPy is the only required Python runtime dependency. OpenCV is optional:

pip install "easy-rtsp[webcam]"

OpenCV powers webcam capture and snapshot encoding. Frame generation, RTSP/file ingest, publishing, and NumPy-only transforms do not require it.

FFmpeg and ffprobe

FFmpeg performs decoding, encoding, and publishing. ffprobe discovers video dimensions and frame rates.

Both may be provided on PATH or explicitly:

$env:EASY_RTSP_FFMPEG = "C:\tools\ffmpeg\bin\ffmpeg.exe"
$env:EASY_RTSP_FFPROBE = "C:\tools\ffmpeg\bin\ffprobe.exe"

export EASY_RTSP_FFMPEG=/usr/local/bin/ffmpeg
export EASY_RTSP_FFPROBE=/usr/local/bin/ffprobe

MediaMTX

MediaMTX provides the proper RTSP server used by local publishing. It is required for:

  • lan_access=True / --lan
  • WebRTC browser playback
  • Multiple RTSP viewers
  • Recording and HLS side outputs when no external RTSP server exists

Install it with:

easy-rtsp install-backends

If it is not on PATH, set EASY_RTSP_MEDIAMTX to the executable.

Confirm the environment

easy-rtsp doctor

The command is safe to include in setup scripts and support requests.
