Hello Hive Community members

## FAQ

#### 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 "npm -- run start" --name video --time --max-memory-restart 6144M -f` - once in life time. Next time onwards, you just need to say `pm2 restart video`

NOTE: Make sure to run `pm2 save` so that if system restarts, you can bring it back to life.

#### What to change in `~/.spk-encoder/config` file?
Update the `gateway_client => gateway_url` value. as follows.

```
  "gateway_client": {
    "gateway_url": "https://encoder-gateway.infra.3speak.tv",
    "queue_max_length": 1,
    "queue_concurrency": 1,
    "async_uploads": false
  },
  "remote_gateway": {
    "api": "https://encoder-gateway.infra.3speak.tv",
    "enabled": true
  },
```

Update the node name, hive name

```
  "node": {
    "name": "Sagar M1 macBookPro",
    "privateKey": "Sxxxxxxxxxxxxxxxxxxxxxxx=",
    "cryptoAccounts": {
      "hive": "sagarkothari88"
    },
    "publicKey": "did:key:zxxxxxxxxxxxxxxxxxxxxxxx"
  },
