# VizionStreamer
|
||||||
|
|
||||||
|
High-performance video streaming application for Vizion cameras with GStreamer integration and Unix Domain Socket control interface.
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
- **Continuous Frame Acquisition**: Dedicated thread for frame capture from VizionSDK
|
||||||
|
- **GStreamer Integration**: Flexible video processing and output
|
||||||
|
- **Socket Control API**: Runtime configuration via JSON commands over Unix Domain Socket
|
||||||
|
- **Camera Parameter Control**: Exposure, white balance, brightness, contrast, etc.
|
||||||
|
- **Multiple Output Options**: Display, UDP/TCP streaming, file recording, RTSP, MJPEG
|
||||||
|
- **Performance Monitoring**: Real-time FPS statistics
|
||||||
|
- **Thread-Safe**: Mutex-protected operations
|
||||||
|
|
||||||
|
## Quick Start
|
||||||
|
|
||||||
|
### Build
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cmake -B build -S .
|
||||||
|
cmake --build build
|
||||||
|
```
|
||||||
|
|
||||||
|
### Run
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Start VizionStreamer
|
||||||
|
./build/vizionStreamer
|
||||||
|
```
|
||||||
|
|
||||||
|
### Start Streaming (Default Pipeline)
|
||||||
|
|
||||||
|
In another terminal:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Start streaming with default pipeline (local display)
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
|
||||||
|
# Stop streaming
|
||||||
|
./scripts/stop_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
That's it! The default pipeline `videoconvert ! autovideosink` is already configured.
|
||||||
|
|
||||||
|

## Configuration Files
|
||||||
|
|
||||||
|
### VxConfig.conf
|
||||||
|
|
||||||
|
Automatically copied to build directory during build. Contains VizionSDK camera configuration.
|
||||||
|
|
||||||
|
## Performance
|
||||||
|
|
||||||
|
The acquisition loop displays statistics every second:
|
||||||
|
|
||||||
|
```
|
||||||
|
FPS: 30 | Total frames: 1234 | Frame size: 4147200 bytes
|
||||||
|
```
|
||||||
|
|
||||||
|
Typical performance:
|
||||||
|
- **Local Display**: 30 FPS @ 1080p
|
||||||
|
- **UDP Streaming**: 30 FPS @ 1080p with H.264 encoding
|
||||||
|
- **File Recording**: Limited by disk I/O
|
||||||
|
|
||||||
|
## Troubleshooting
|
||||||
|
|
||||||
|
### No cameras found
|
||||||
|
- Check camera connection
|
||||||
|
- Run `/opt/vizionsdk/init_driver.sh` if needed
|
||||||
|
- Check `dmesg` for USB errors
|
||||||
|
|
||||||
|
### Pipeline fails to start
|
||||||
|
- Verify GStreamer plugins are installed
|
||||||
|
- Test pipeline manually: `gst-launch-1.0 videotestsrc ! YOUR_PIPELINE`
|
||||||
|
- Check pipeline syntax
|
||||||
|
|
||||||
|
### Socket connection refused
|
||||||
|
- Ensure VizionStreamer is running
|
||||||
|
- Check socket exists: `ls -l /tmp/vizion_control.sock`
|
||||||
|
- Verify permissions
|
||||||
|
|
||||||
|
### Low FPS
|
||||||
|
- Reduce resolution or framerate
|
||||||
|
- Use hardware encoding if available (`vaapih264enc` instead of `x264enc`)
|
||||||
|
- Check CPU usage

||||||

# VizionStreamer Control Scripts
|
||||||
|
|
||||||
|
Diese Scripts ermöglichen die schnelle Steuerung von VizionStreamer über die Unix Domain Socket API.
|
||||||
|
|
||||||
|
## Voraussetzung
|
||||||
|
|
||||||
|
VizionStreamer muss laufen:
|
||||||
|
```bash
|
||||||
|
cd /home/maik/CLionProjects/vizionStreamer
|
||||||
|
./build/vizionStreamer
|
||||||
|
```
|
||||||
|
|
||||||
|
## Schnellstart (Standard-Pipeline)
|
||||||
|
|
||||||
|
Die Standard-Pipeline `videoconvert ! autovideosink` ist bereits gesetzt. Einfach starten:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
Das Video wird lokal angezeigt. Zum Stoppen:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
./scripts/stop_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
## Pipeline ändern
|
||||||
|
|
||||||
|
### Lokale Anzeige (Standard)
|
||||||
|
```bash
|
||||||
|
./scripts/set_pipeline_display.sh
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### UDP-Streaming (H.264)
|
||||||
|
```bash
|
||||||
|
# Standard: 192.168.1.100:5000
|
||||||
|
./scripts/set_pipeline_udp.sh
|
||||||
|
|
||||||
|
# Eigene IP/Port
|
||||||
|
./scripts/set_pipeline_udp.sh 192.168.1.50 5001
|
||||||
|
|
||||||
|
# Dann starten
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
**Stream empfangen:**
|
||||||
|
```bash
|
||||||
|
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264 ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! autovideosink
|
||||||
|
```
|
||||||
|
|
||||||
|
### Aufnahme in Datei
|
||||||
|
```bash
|
||||||
|
# Standard: /tmp/vizion_recording.mp4
|
||||||
|
./scripts/set_pipeline_file.sh
|
||||||
|
|
||||||
|
# Eigene Datei
|
||||||
|
./scripts/set_pipeline_file.sh /home/user/videos/recording.mp4
|
||||||
|
|
||||||
|
# Dann starten
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
### MJPEG HTTP-Stream
|
||||||
|
```bash
|
||||||
|
# Standard: Port 8080
|
||||||
|
./scripts/set_pipeline_mjpeg.sh
|
||||||
|
|
||||||
|
# Eigener Port
|
||||||
|
./scripts/set_pipeline_mjpeg.sh 8090
|
||||||
|
|
||||||
|
# Dann starten
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
**Stream ansehen:**
|
||||||
|
```bash
|
||||||
|
# Im Browser
|
||||||
|
firefox http://localhost:8080
|
||||||
|
|
||||||
|
# Mit FFplay
|
||||||
|
ffplay http://localhost:8080
|
||||||
|
```
|
||||||
|
|
||||||
|
## Status & Information
|
||||||
|
|
||||||
|
### Status abfragen
|
||||||
|
```bash
|
||||||
|
./scripts/get_status.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
Zeigt:
|
||||||
|
- Streaming-Status (läuft/gestoppt)
|
||||||
|
- Aktuelle Pipeline
|
||||||
|
|
||||||
|
### Verfügbare Formate
|
||||||
|
```bash
|
||||||
|
./scripts/get_formats.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
Zeigt alle verfügbaren Kamera-Auflösungen und Formate.
|
||||||
|
|
||||||
|
## Typischer Workflow
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# 1. VizionStreamer starten (Terminal 1)
|
||||||
|
./build/vizionStreamer
|
||||||
|
|
||||||
|
# 2. Status prüfen (Terminal 2)
|
||||||
|
./scripts/get_status.sh
|
||||||
|
|
||||||
|
# 3. Pipeline für UDP-Streaming setzen
|
||||||
|
./scripts/set_pipeline_udp.sh 192.168.1.100 5000
|
||||||
|
|
||||||
|
# 4. Streaming starten
|
||||||
|
./scripts/start_stream.sh
|
||||||
|
|
||||||
|
# 5. Stream empfangen (auf Zielrechner)
|
||||||
|
gst-launch-1.0 udpsrc port=5000 ! application/x-rtp,encoding-name=H264 ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! autovideosink
|
||||||
|
|
||||||
|
# 6. Bei Bedarf stoppen
|

## Wichtige Hinweise
|
||||||
|
|
||||||
|
- Pipeline kann nur geändert werden, wenn Streaming gestoppt ist
|
||||||
|
- Standard-Pipeline ist bereits gesetzt - kein `set_pipeline` vor dem ersten Start nötig
|
||||||
|
- Mit `start_stream.sh` sofort loslegen!
|
||||||
|
- Alle Scripts benötigen `socat` (installieren mit: `sudo apt install socat`)
|
||||||
|
- Status-Scripts benötigen optional `python3` für formatierte JSON-Ausgabe
|
||||||
|
|
||||||
|
## Eigene Pipelines
|
||||||
|
|
||||||
|
Sie können jede beliebige GStreamer-Pipeline verwenden:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
SOCKET="/tmp/vizion_control.sock"
|
||||||
|
echo '{"command":"set_pipeline","params":{"pipeline":"IHRE_PIPELINE"}}' | socat - UNIX-CONNECT:$SOCKET
|
||||||
|
```
|
||||||
|
|
||||||
|
Beispiele:
|
||||||
|
- `videoconvert ! xvimagesink` - Einfache lokale Anzeige
|
||||||
|
- `videoconvert ! x264enc ! flvmux ! rtmpsink location=rtmp://server/live/stream` - RTMP-Streaming
|
||||||
|
- `tee name=t ! queue ! videoconvert ! autovideosink t. ! queue ! x264enc ! filesink location=out.mp4` - Gleichzeitig anzeigen und aufnehmen
