RTV

Broadcasting the latest and greatest generative AI, direct to your web browser.

RTV takes a series of prompts and feeds them through andreasjansson/tile-morph to create a tiled animation drifting through latent space.

It is broadcast on the Replicate home page. If you want to edit our home page, contribute some prompts!

How to add prompts

Stick 'em in prompts.json.

How to run it

You need to set REPLICATE_API_TOKEN and RTMP_URL in your environment then run node writer.js and node broadcaster.js in separate terminals.

How it works

Two bits:

Writer

Writer generates tiles on Replicate. They are saved as a queue in the directory queue as ordered JSON files.

It will generate tiles in parallel at whatever rate is needed to keep a 5 minute buffer.

Broadcaster

Broadcaster takes tiles in the queue directory and broadcasts them in order to Mux using ffmpeg. When a tile has been successfully broadcast, it gets deleted from the queue.

Deploy

fly deploy

Debugging

If things get stuck, you can SSH into the Fly instance and look at the queue:

$ fly ssh console                                                                                                                                                            !10251

Fix it when it breaks

fly logs will tell you what broke.

fly apps restart rtv might fix it.

fly ssh console then rm /src/queue/* if it's really broke.
