Hello all. New to the framework (and elixir) and still a little fuzzy on how to implement my idea. Basically I want to stitch together a bunch of wav and/or mp3 files and stream them indefinitely. Like a queue where I can keep adding files and the pipeline should grab them as needed FIFO style. The files will be downloaded via HTTP. So what I'm currently envisioning is a Bin that uses a Hackney source element to grab the file and push it on down. Then, when it's done it will get replaced with a new Hackney source pointing to the next file. Does that sound like the right idea, and are there any good examples you can point me to that do something similar?
