Prerequisites

To build from source, you need to have Go 1.14 or newer installed.

Design

Voodfy Transcoder is a queue system used on core of Voodfy to ingest videos using Livepeeer and sendding to IPFS/Filecoin using Powergate

Here's a high-level overview of the main components, and how Powergate interacts with IPFS and a Filecoin client:

Note in the diagram that the Lotus, Filecoin, IPFS, and Powrgate client node doesn't need to be in the same host where Voodfycli is running. They can, but isn't necessary.

To build and install the CLI, run:

$ make build-cli

The binary will be placed automatically in $GOPATH/bin which in general is in $PATH, so you can immediately run voodfycli in your terminal.

You can run voodfycli with the --help flag to see the available commands:

$ voodfycli --help
NAME:

   signup, s         setup an account at Voodfy
   login, l          login at Voodfy
   add, a            add a video to transcode
   ipfs, ipfs        send the result video transcoded to IPFS
   directory, dt     get a directory giving the resource id
   store_config, sc  show the default config at Filecoin
   store, st         store the resources on Filecoin

   help, h           Shows a list of commands or help for one command

GLOBAL OPTIONS:
   --help, -h     show help
   --version, -v  print the version

Example

Setup an account at Voodfy

Use the signup or login before any action

Using the signup the prompt will ask your a secret after this store the ouput with safety

$ REDIS_BROKER="localhost:6379" REDIS_RESULT="localhost:6379" voodfycli signup

To login use the secret generated by signup

$ REDIS_BROKER="localhost:6379" REDIS_RESULT="localhost:6379" voodfycli login

Example using the command add to transcode a video

Adding a video it's necessary to specify the full directory path

$ REDIS_BROKER="localhost:6379" REDIS_RESULT="localhost:6379" voodfycli add `environment` `directory` `filename` `resource_id` `tracker`

Adding to IPFS

To add to IPFS it's necessary the resourceId directory tracker

$ REDIS_BROKER="localhost:6379" REDIS_RESULT="localhost:6379" voodfycli ipfs `directory` `resourceID`

Storing a resource id on Filecoin

Storing the directory at Filecoin by Powergate is very simple.

$ REDIS_BROKER="localhost:6379" REDIS_RESULT="localhost:6379" voodfycli store `resource_id`

Installation

Voodfy transcoder installation involves running external dependencies, and wiring them correctly with Filecoin/Lotus IPFS and Powergate.

Please copy the example_conf/app.ini example hosted in this repository creating a folder called with app.ini inside conf/app.ini

External dependencies

Powergate needs external dependencies in order to provide full functionality, in particular a synced Filecoin client and a IPFS node and a Redis running.

Filecoin client

Currently, we support the Lotus Filecoin client.

Fully syncing a Lotus node can take time, so be sure to check you're fully synced doing ./lotus sync status.

IPFS node

A running IPFS node is needed.

Its Dockerhub repository if you want to run a contanerized version. Currently we're supporting v0.5.1. The API endpoint should be accessible to Powergate (port 5001, by default).

Queue system

To build the Powergate server, run:

$ make up

We'll soon provide better information about the integration with Lotus/Filecoin, IPFS and Powergate configurations, stay tuned! 📻

Contributing

This project is a work in progress. As such, there's a few things you can do right now to help out:
