Stable Video Diffusion on Livepeer

This repository has two parts in the same api server:

  • Front end: provides the html interface to request the processing
  • Back end: runs the processing of stable video diffusion on the GPU
  • Both can be ran on same machine or on separate machines.
    • The RUN_FRONTEND setting in start script includes the frontend endpoints in the api
    • The RUN_PROCESSING setting in the start script loads the model onto the gpu and runs the stable vidoe diffusion inference

Installation

  • setup go-livepeer using av-livepeer-external-capabilities branch of ad-astra-video/go-livepeer
    • Docker image available at adastravideo dockerhub
      • note: images will update with new builds regularly so pulling new images may break things
  • setup this repo services
    • clone repository to local machine
    • run setup script (.sh if on linux, .bat if on windows)
    • run check_cuda_devices.py to get ordering of GPUS if have more than one
    • copy the example_start script and rename to use with settings specific to your machine.
      • update the GO_LIVEPEER_URL to point to orchestrator public https url
      • if running processing and front end on same machine change RUN_PROCESSING to "yes"
        • set the "backend processing setup variables"

  • Additional Setup

    • go-livepeer needs real SSL cert to get requests directly to orchestrator (no self signed cert)

      • code update is included in av-livepeer-external-capabilities that preents go-livepeer from generating a new cert.pem and key.pem at every startup

    • commands to get SSL cert from lets encrypt with DNS challenge. - install certbot

          sudo apt-get install certbot
    sudo certbot certonly --manual --preferred-challenges dns -d "*.{DOMAIN}"
    //now set the TXT record on dns and verify with https://mxtoolbox.com/txtlookup.aspx
    //create symlink to go-livepeer install path for certs created
    cd [path to go-livepeer datadir]
    rm cert.pem key.pem
    cp [path to letsencrypt cert] ./cert.pem
    cp [path to letsencrypt key] ./key.pem
    chown [user]:[user] cert.pem
    chown [user]:[user] key.pem

    TODO

    • consider moving the eth account signing to python server process
      • will allow unlocking account and signing with less prompting and is likely more secure
