Start plex transcode/stream

Hi,

I’m working on some cloud app development at the moment and was wondering if anyone could point me in the right direction as to what function would be used to start a transcode stream?

I’ve managed to login and obtain the X-Plex-Token after a successful login from the user, I can also get all the library information by the following - http://{host}:{port}/library/sections/

And getting the media information from - http://{host}:{port}/library/metadata/{ratingkey}

But what would I call to start a stream? Any help and/or advice would be great as I’d like to get it to transcode into H264/AAC(MP4 Format) if possible

Thanks in advance.
