Streaming in a HTML5 video player

[goodtube4u]

describe the feature you'd like to see
Would be really awesome if we could somehow stream these videos in a HTML5 video element!
Currently I can access the stream URL via the /api/json/ endpoint. However, if I then add that as the src of a video element, seeking does not work at all (even once the video has finished / downloaded fully).

Not sure if this is possible already? So far I can't work it out unfortunately. Any advice here would be greatly appreciated.

describe alternatives you've considered
I've tried HLS streaming and HTTP streaming plugins for one of the most common video players - Video JS.
However these need a .m3u8 playlist file - which currently isn't being returned by the API.
I think these can easily be generated by FFMPEG, any chance of generating and passing them as part of the JSON data returned from the /api/json api endpoint?
