As described here Wowza-Docs: “how-to-configure-closed-captioning-language-selection-for-video-on-demand-streaming#using-multi-language-caption-files” WSE might support multilanguage webVTT files. But I did not find the propper format for that. I assume a smil file must be created like this example Wowza-Docs: “how-to-stream-webvtt-subtitles-to-ios-for-closed-captioning#play-using-a-smil-file” with 2 or more languages as system-language and src pointing to one vtt file. Does somebody got that running? How must the vtt file be structured and the languages be separated if they are in one file.
Right now I record them in separated files (one per language). But as it looks like multiple files are not supported in the smil configuration. In this case only the first caption language is working, even if the lables for the others are visible in the player.
