Hello Wowza Community!

Rob Poach here, your friendly neighborhood Global Head of Customers, with something new for our community: **Wowza Voice of the Customer Updates**.

Our Technical Support team works 24/7 (literally) helping Wowza customers solve technical challenges and get the most out of our products. Along the way, we see many of the same questions, challenges, and use cases come up across our customer base.

We’re taking those real-world customer experiences and turning them into practical blog posts designed to help the broader Wowza community troubleshoot issues, learn best practices, and hopefully answer some questions before you even need to open a ticket.

Please enjoy today’s entry, and keep an eye out for more Voice of the Customer Updates to come.

Thank you again, and thank you for choosing Wowza!

Rob

**WebVTT Captions in Wowza Streaming Engine: Live, VOD, and Broadcast Sources**  
Captions now run through nearly every streaming workflow, from AI-generated live transcripts to broadcast subtitles repurposed for web playback. Wowza Solutions Architech - Ian Zenoni’s updated guide explains how Wowza Streaming Engine generates and delivers WebVTT captions across HLS, CMAF HLS, and CMAF MPEG-DASH, and covers:

- How WebVTT compares to SRT, CEA-608/708, and TTML
- Converting DVB Teletext subtitles from live MPEG-TS streams into WebVTT tracks
- Adding real-time captions with the Wowza Caption Handlers plugin and ASR engines such as Azure AI Speech Services and OpenAI Whisper
- Attaching captions to adaptive bitrate VOD streams through the SMIL file
- Four common reasons captions fail to appear, including companion file naming and caption provider settings
