# Text with custom font size
python3 scripts/send2tv.py "Warning!" --font-size 300

# Image file
python3 scripts/send2tv.py --image /path/to/photo.jpg

# Image with text overlay
python3 scripts/send2tv.py --image /path/to/photo.jpg --text "Hello!"

# TTS - Text to speech (requires edge-tts skill)
python3 scripts/send2tv.py --tts "这是一段要朗读的文字"
python3 scripts/send2tv.py --tts "Hello world" --voice en-US-MichelleNeural
python3 scripts/send2tv.py --tts "快点！" --rate +20%

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

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

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)
