Writing these notes for future reference:

We need to use GetMovieDetails with the movie ID in order to get the filepath like in this python example: json_query = xbmc.executeJSONRPC('{"jsonrpc": "2.0", "method": "VideoLibrary.GetMovieDetails", "params": {"properties": ["file", "imdbnumber", "year", "trailer", "streamdetails", "art"], "movieid":%s }, "id": 1}' %dbid)

Then we can use Files.PrepareDownload to get a url we can playback:
curl --user kodi:kodi --header "Content-Type: application/json" --data '{"jsonrpc":"2.0", "id":1, "method":"Files.PrepareDownload", "params":{ "path": "/home/a1rwulf/Videos/moviecuts/2_Fast_2_Furious/2_Fast_2_Furious.mkv" }}' 'http://127.0.0.1:8080/jsonrpc'

We can playback that url in the browser with a HTML5 player(only will support some formats, if we ever get transcoding working we could support every format)
