Hello 3Speak & Hive Community members,
Most of my posts are related to 3Speak Mobile App & its development.
This post is slightly different. I'm going to attempt some of the known issues of video-encoder nodes. I'm going out of my comfort zone one more time & see what I can do & contribute here.
What is HLS (HTTP Live Streaming)?
- 3Speak is video streaming platforms
- It uses HLS to provide a better experience to their audience.
- Some times we are on the move and watching something while traveling. In such cases, HLS is very helpful.
- If you're traveling & from 4G, your connection drops to poor reception, HLS comes in handy.
- HLS adjusts automatically & decreases video quality to give you a stutter-free experience.
- It automatically switches from HD (1080p) resolution to 480p video resolution for streaming.
Where do I see HLS settings?
- you can find it on the bottom-right corner of the player
- Here is an example for you.
Why? Video-encoder node
- Why do we need video-encoder nodes?
- Users - they have raw videos in
*.mp4,*.movor any other extension. - These raw videos have to be processed to make it HLS compatible.
- In video encoding process, original video is resized to 480p, 720p & 1080p
- After that, each resized video is chopped down into media segments.
- Once done, HLS Video (these 3 processed videos) is uploaded & pinned to IPFS infra.
Why am I touching video-encoder?
- There are some known issues with video-encoder nodes.
- Improving IPFS pinning efficiency
- Faster & efficient video encoding
- Above are few examples to have better/improved video encoder nodes.
- Instead of working & focusing only on mobile-app, this would be the new area which I would be exploring & try contributing something over here.
Where is video-encoder node code?
- Video-encoder node - source code is open-source
- It's available here - https://github.com/spknetwork/video-encoder
- Any one can check it out & run it to earn 1% as a beneficiary on each video encoded.
Prerequisites & basic setup
- IPFS Cluster Instance - https://ipfscluster.io/
- IPFS Instance -
- NodeJS - 16.x
- FFMPEG
- These prerequisites can be solved by running followings on a Linux computer (good processing speed & internet recommended)
nodejs & pm2 installation
sudo apt update
sudo apt upgrade -y
curl -fsSL https://deb.nodesource.com/setup_16.x | sudo -E bash -
sudo apt install nodejs -y
sudo apt install npm -y
hash -r
sudo npm install -g npm
npm i -g pm2
Install ffmpeg
sudo apt install ffmpeg
Install Kubo(IPFS)
wget https://dist.ipfs.tech/kubo/v0.18.1/kubo_v0.18.1_linux-amd64.tar.gz
tar -xf kubo_v0.18.1_linux-amd64.tar.gz
cd kubo
chmod +x install.sh
./install.sh
Run IPFS
ipfs init --profile server
pm2 start "ipfs daemon" --name ipfs
Clone the project
git clone https://github.com/spknetwork/video-encoder.git
How did I do with my local setup?
README.mdsays follow this for local experimental node.- If you want to run the experimental client
npx ts-node client.js
- I tried it but It failed for me.
ā video-encoder git:(main) npx ts-node client.js
node:internal/modules/cjs/loader:1080
throw err;
^
Error: Cannot find module './client.js'

]
}
Node.js v18.18.2
- My best guess is - It's nodejs version.
- Let's try switching the nodejs to 16
- I did try & it didn't work.
Run locally in dev mode
- I tried
npx ts-node client.jswhich failed for me. - So, I started looking into
package.json. - There I found the script to run it locally as dev
- It did the trick & now, I've a local dev video-encoder node running.
What's next?
- Now that I am able to run video-encoder-node locally in dev mode, I've following action items.
- Get basic understanding of javascipt, typescript, ffpmeg commands.
- Look at the existing source code of video-encoder-node.
- Get an overview / basic understanding of how it works.
- Try injecting a local video to encode & debug
- Improve video-encoder-node efficiency by tweaking video-encoding ffmpeg commands
