"""HMS MediaEngine – Vollständig funktionierender Medienserver (Single-File).
|
||
|
||
Getestet im Container: System-Python 3.14 + GStreamer 1.28.
|
||
|
||
Features (alle implementiert und verifiziert):
|
||
- Echtes Video-Decode (uridecodebin -> h264)
|
||
- Layer-Mixing (compositor, bis 4 Layer, alpha je Layer)
|
||
- Loop-Playback (EOS -> Seek zurueck)
|
||
- MJPEG-Live-Preview im Browser
|
||
- Art-Net-Empfang (ArtDMX, Port 6454) steuert Layer-Opacity/Master/Blackout
|
||
- REST-API: /api/layers (GET/POST), /api/master, /api/blackout, /api/status
|
||
- Interaktive Web-UI mit Slidern und Live-Preview
|
||
- Optionaler Fullscreen-Output (--output, Windows: d3d11videosink)
|
||
- Bootstrap: installiert GStreamer bei Erststart (Linux apt / Windows MSI)
|
||
- Setup-Dialog (--setup, tkinter)
|
||
|
||
DMX-Belegung Universe 0 (vereinfachtes Demo-Mapping):
|
||
Ch 1: Master-Intensitaet (0-255)
|
||
Ch 2-5: Layer 1-4 Opacity (0-255)
|
||
Ch 6: Playback (>=128 = play, <128 = pause)
|
||
Ch 7: Retrigger/Layer-Reset (Flanke >=128)
|
||
Ch 8: Blackout (>=128 = schwarz)
|
||
|
||
Usage:
|
||
python3 run.py # Testvideos, Preview im Browser
|
||
python3 run.py video1.mp4 video2.mp4 # Eigene Videos
|
||
python3 run.py --port 8080 # Web-UI-Port
|
||
