How to setup 3Speak Video Encoder node?

🙏 Namaste Hive Community members

With this video, I'll illustrate how to set up the encoder node on your system.

FAQs

First of all what is encoder node?

So, whenever someone uploads a video to 3speak, it has to be processed. You might be wondering what processing?
Imagine you uploaded a video from your iPhone 12 Pro with highest resolution and video size is up-to 1 GB.
Do you want your users with low data bandwith to suffer? Of course you won't.

So, encoder nodes will encode the video into different sizes like 480, 720, 1020 etc so that it can be viewable with limited data badnwith.
Video encoding is high processing task.

Now imagine, there are many users uploading video, 3speak can not limit itself to just 2-3 computers for encoding.
It may result in-to long queue and users may have to wait for video to get published.
and if 3speak does that, it becomes a centralised service provider which 3speak wants to avoid.
It has to be community driven.

This is where encoder-node-operator comes into picture.
Community powers the community.
They share the load, they take the job of video-encoding and guess what they also get reward of 1% as a beneficiary.

What kind of system do I need?

Anything which has processing power more than intel i7.

Do I need graphic card?

Not at all.

What kind of internet connection do I need?

You need a wired connection. Wifi would work but you'll get lesser jobs because of fluctuating internet connection.

How much internet speed is required?

Anything above 40 mbps

How much RAM is required?

Anything above 8 GB

What operating system is required?

You can use any operating system - macOS, ubuntu, windows.

What softwares are required?

You need nodejs 16, and ffmpeg installed on your system.

Would VPS work?

I wouldn't recommend. I paid for heavy-weight contabo server for over a year & it does not encode a single video in a day.
But if you want to try, Give it a try. I wouldn't stop you :)

Steps to setup encoder node

Setup PM2 (if you already have PM2, skip this)

1. Run command npm install pm2 --global

Setup IPFS (if you already have IPFS, skip this)

1. Open https://dist.ipfs.io/#go-ipfs
2. Download binary (based on your OS)
3. Run install.sh command which is inside downloaded zip file.
4. Go to your work directory e.g. ~/Users/sagar
5. Run ipfs init - this you would run once in life time.
6. Run pm2 start "ipfs daemon" --name ipfs - again once in life time.
   Next time onwards, you just need to say pm2 restart ipfs

Setup FFMPEG

Please google yourself - "how to install ffmpeg"

Setup video encoder node

1. Open terminal & navigate where you want to setup encoder-node
   e.g. ~/Users/sagar/projects
2. Run git clone https://github.com/spknetwork/video-encoder.git
3. cd video-encoder
4. npm install --force
5. npm run build
6. pm2 start dist/index.js --name video --max-memory-restart 6144M -f - once in life time. Next time onwards, you just need to say pm2 restart video
