9. Common Troubleshooting Checklist

| Symptom | Likely cause | Fix | |---------|--------------|-----| | No video, black screen | Camera driver not loaded / wrong device ID. | Re‑install driver, check Device Manager, select correct ID. | | Audio missing | Camera’s mic disabled or driver lacks audio support. | In FaceMP4 Settings → “Audio Source”, pick the correct mic or enable it in the driver’s control panel. | | Application crashes on start | Missing VC++ redistributable or outdated OS. | Install latest Microsoft Visual C++ 2015‑2022 runtime, update Windows. | | High CPU usage | Software decoding instead of GPU. | Enable hardware acceleration, lower resolution/FPS. | | Laggy network stream (RTSP) | Bandwidth limitation, router QoS, or wrong port. | Use a wired Ethernet connection, open port 554 on router, reduce bitrate. | | Recording stops after a few minutes | Disk space runs out or power‑saving setting puts camera to sleep. | Increase disk capacity, disable Windows “Turn off hard disk after …” and camera’s “Power Save” mode. |

9️⃣ Troubleshooting Cheat‑Sheet

| Symptom | Likely Cause | Quick Fix | |---------|--------------|-----------| | No /dev/video0 | Camera not enumerated / power issue | Re‑plug USB, check dmesg, ensure 5 V/2 A supply. | | Pixelated video | Bitrate too low for resolution | Increase -b/bitrate (e.g., 8M for 4K). | | Audio missing | Facemp4 only handles video; add an external mic capture & mux with ffmpeg. | | Service won’t start | Permissions on /var/lib/facemp4 | sudo chown -R root:video /var/lib/facemp4 && sudo chmod -R 755 /var/lib/facemp4 | | Stutters at 30 fps | CPU saturation (especially on low‑end SBCs) | Lower framerate to 25 fps or use hardware‑accelerated H.264 (-hwaccel). | | RTMP connection fails | Wrong URL or firewall | Verify port 1935 open, test with ffprobe first. | 📹 Quick‑Start Guide **Installing ** Facemp4 on the

6.2. Recording only when a face is present

facemp4 \
  --device 0 \
  --output shweta_cam_if_face.mp4 \
  --detect-faces \
  --record-on-face \
  --min-face-duration 2   # start recording after a face has been present for 2 s

8️⃣ Optional: Live Streaming (RTMP / RTSP)

If you enabled -DENABLE_RTMP=ON during the CMake step, you can push a live feed directly:

facemp4-stream \
    -d /dev/video0 \
    -r 1920x1080 \
    -f 30 \
    -b 5M \
    -o rtmp://your.cdn/live/shweta

For RTSP (e.g., use with VLC, OBS, or a private Nginx‑rtsp server): Who this is for – Anyone who already

facemp4-stream \
    -d /dev/video0 \
    -r 1280x720 \
    -f 25 \
    -b 3M \
    -o rtsp://0.0.0.0:8554/shweta

You can add the above command to the daemon’s config (stream_url=) or launch it in a screen/tmux session.
