Hello, I have created a upload preset that uses Eager Transformations: sp_4k/m3u8 to convert simple mp4 files to adaptive m3u8 playlist files. I'm then feeding a capable web video player (not the cloudinary player) the m3u8 file and it nicely streams adaptively to the network bandwidth and so on.
However, I am having troubles with subtitles. The video player is based on hls.js which should be capable of handling captions when included in the playlist file (the m3u8) but I can't find blog post, forum post or documentation about how to add captions to cloudinarys adaptive streaming playlists. Is it even possible? I know an obvious answer would be: "just use the cloudinary player and feed the subtitles separately" but it's simply not a option so that wont solve my current need unfortunately.
I hope that someone can shine some light to what needs to be done or whether this is even possible?
