Hi,

please open a [support ticket](https://support.wowza.com/techsupport-request) from your Wowza account with a detailed issue description, so we can help in your individual use case. Also include your [conf and log files](https://www.wowza.com/docs/how-to-create-a-compressed-zip-file-in-windows-os-x-and-linux) please.

A couple of hints:

- [https://www.wowza.com/docs/How-to-configure-closed-captioning-for-video-on-demand-streaming#closed-captions-configuration10](https://www.wowza.com/docs/How-to-configure-closed-captioning-for-video-on-demand-streaming#closed-captions-configuration10)

- This property **: vodcaptionprovidersrt** – Pulls captions from an external SRT-formatted caption file in the same location as the VOD asset.

- Wowza Streaming Engine does not support using multiple caption languages with SRT and SCC caption sources for VOD streams.

- Place the TTML (.ttml), SRT (.srt), WebVTT (.vtt), or SCC (.scc) caption file next to the video asset file in the **[install-dir]/content** folder and ensure that the root file name of the caption file is the same as that of the asset file (for example, **sample.ttml** and **sample.mp4** or **sample.smil** ). This allows the corresponding **VODTimedTextProvider** to find the file and ingest it for caption insertion during playback.

- It seems you don’t have the .srt file name as of the asset file.

> Note: If no caption language is defined in the stream URL or in the application’s properties, Wowza Streaming Engine uses the first caption language it finds in the first caption source it checks within the source media. The caption source it checks first is based on the order of Closed Caption Sources in the application’s Setup tab).
