HackFS 2023 Hackathon. IPFS — Best Use and libp2p — Best Use.

Getting started

pnpm run start

pnpm run rust-peer

streaming

1. Test streaming with 'node:fs'

   pnpm run stream:base

2. Create helia stream

   pnpm run stream:helia

3. Streaming with known cid

   pnpm run stream:cid QmPvt66qGviw7T6r6Qe2Lhpgj6YCpexv8gz7SKXEHq4FD3

Testing

Run

pnpm test

Peer Streaming with hypercore

1. Convert video into a core

   pnpm run hypercore:convert

2. Replicate so other peers can also watch it

   pnpm run hypercore

3. Other peers can join with the core key

   pnpm run hypercore:peer ec429308a714b51a79b583627cc705e6eaf5f6f681a3b7158138ca315dbaea46

   

Adding movies to ipfs

1. Create a movie/ direcory and add movie.mp4 and thumbnail.png or .jpg

   mkdir movie

2. Add and pin movie to ipfs

   ipfs add -r ./movie/
   
   # then
   ipfs pin add QmPzE1...

   Next, You can run ipfs ls QmPzE1rSLhhVvdfyAZkjAuf8KSCxtKbepPZJ99weKFcZHP to see the contents of your movies e.g

   QmVzmsRo6avD1HeBWY3WTUGdqvhya4KK999k77nFZS7i2S 63614462 bigbuck.mp4
   QmcgoEmVE3iSbqGS1Pr5Ad5jASMyGFBLA5wfHKKtb1vSRa 582477   thumbnail.png
   

3. Next, let's can try stream movies ipfs

Possible Implentations

1. IPFS Live Streaming by Yurko,Elon, Benedict and Toronto Mesh - Feed video file into the IPFS and distribute content hash
   1. OBS Studio
   2. OpenVPN
   3. Digital Ocean (Host HLS playlist over HTTP)
   4. NGINX with RTMP module (Video source from RTMP server)
   5. FFmpeg (create an HLS stream of chunks)
   6. IPFS (Add to IPFS) - Publish hash to rewrite m3u8 playlist file to IPNS ()
   7. Video.js
   8. Terraform

Additional implementation

You can use FFMpeg to encode Video Stream into chunks and advertise to a gossip network. Possibly an idea to scale the video streaming? - DougAnderson444#7580

1. Chunk video into mu8 playlist
2. To announce video chunks to a gossip channel via gossip protocol pubsub

MISC: Append only hyperswarm

• Create car file

• Adding swarm to have topics that other peers can join

  pnpm run hyperswarm
  
  # then other peers can join with, able to chat on terminal
  pnpm run hyperswarm (topic)

• Append only persistent messages storage

  pnpm run hypercore:writer
  # then
  pnpm run hypercore:reader
  
  # writer can send messages to writer
