Open-source video infrastructure services on Ethereum Blockchain.
Objective: do stuff the internet needs for video:
decentrally
permissionlessly
open-source
Crypto-economically incentivised:
Inflation Funding Token (LPT)
Reward to nodes providing capacity to the network
"Continuous funding" mechanism (!)
https://coinmarketcap.com/currencies/livepeer/
Delegated Proof-of-Stake Protocol
on Ethereum mainnet
launched April 2018
Current Primary Focus: Transcoding Marketplace
GPU Mining
Probabilistic Micropayments
Current Secondary Focus: Protocol Governance
Voting
Community Engagement
livepeer.org github.com/livepeer
Project building on Livepeer
Decentralised Autonomous Community (not Organisation)
Funded via Livepeer's Inflation Funding Token (LPT)
Current Primary Focus: Stream-to-Earn / Pay-to-play
Payment in crypto
Real-time monetisation
See demo later...
Current Secondary Focus: Onboarding Community
Raising awareness of opportunities
Helping people who want to use it

Overview of simple-streaming-server
Objective: make it incredibly simple to get started using Livepeer.
-
Download and unzip latest binaries from Livepeer Releases Page
wget https://github.com/livepeer/go-livepeer/releases/download/v0.5.7/livepeer-linux-amd64.tar.gz
tar -xzf livepeer-linux-amd64.tar.gz
-
Run a Broadcaster using Livepeer:
./livepeer-linux-amd64/livepeer -broadcaster -v 99
[ switch to terminal ]
-
Publish a test signal into the Broadcaster:
ffmpeg
-re
-f lavfi
-i testsrc=size=640x360:rate=30,format=yuv420p
-f lavfi
-i sine
-threads 1
-c:v libx264

-c:a aac
-f flv rtmp://127.0.0.1:1935/hello_world[ switch to terminal ] -
Play back the source stream:
(if I have time)
-
Publish a livestream signal into the Broadcaster in OBS
https://github.com/videoDAC/community/blob/master/CREATOR-ONBOARDING.md
-
Play back the source stream using VLC Player
- What is a Template?
Objective: make it really easy for people to launch an app of their own
paying directly to a configured address :)
using their own simple-streaming-server
-
Simple User Experience
Tap to turn on TV Tap to turn off TV
-
Published in android repo of videoDAC project
-
Built with Gitcoin
-
Connext 2.0 - payment-per-second
Preparation
-
Install Android Studio
-
Download the code repo containing the template
git clone https://github.com/videoDAC/android.git
Demo
- Run Android Studio /usr/local/android-studio/bin/studio.sh
- Load template in Android Studio
- Change the package name from com.videodac.hls
- Change the variables - configure to your own preferences
