How It Works

Image/Text mode: 1. Renders text to 1920x1080 black image (or serves image directly) 2. Starts local HTTP server on port 8082 3. Sends DLNA/UPnP SOAP SetAVTransportURI + Play commands to TV 4. TV downloads image via HTTP and displays it

Audio mode: 1. Prepares audio file (converts to MP3 if needed) 2. Starts local HTTP server on port 8082 3. Sends DLNA/UPnP SOAP commands to TV 4. TV streams audio via HTTP and plays it

TTS mode: 1. Uses edge-tts to convert text to speech 2. Pushes audio to TV via DLNA

TV Configuration

  • IP: 192.168.3.252
  • UPnP Port: 25826
  • HTTP Server Port: 8082
  • UPnP Service: urn:schemas-upnp-org:service:AVTransport:1

    • Font Notes

  • Chinese text uses WenQuanYi Zen Hei (文泉驿正黑), auto-detected
  • English text uses DejaVu Sans Bold
  • Font auto-scales to fit 1920x1080 (90% width max)

    • TTS Voices (for --tts mode)

    Chinese:

  • zh-CN-XiaoxiaoNeural - female, natural (default)
  • zh-CN-YunyangNeural - male, natural
  • zh-CN-XiaoyiNeural - female, sweet
  • zh-CN-YunjianNeural - male, mature

    • English:

  • en-US-MichelleNeural - female, natural
  • en-US-AriaNeural - female, natural
  • en-US-GuyNeural - male, natural

    Troubleshooting

    TV转圈不显示: 端口8082被防火墙拦。需要在Windows防火墙添加入站规则允许8080-8090端口。

    文字太小/太大: 用 --font-size 调整，默认200像素。

    图片推送失败: 确认图片路径存在且为有效图片文件。

    音频不播放: 确认电视支持MP3格式，检查DLNA服务是否开启。

    TTS失败: 确认已安装 edge-tts skill (skillhub install openclaw/skills/edge-tts)
