Video Configuration

Ugh I hate this page. I think its best to move everything to quickstart and have this be a comprehensive flag overview

TL;DR Configuration

If you just want a working video gateway, use the below command:

Off-Chain
On-Chain

Replace with your locally running orchestrator http address.

Off-Chain Video Gateway

livepeer -gateway \
  -network offchain \
  # Minimum required video flags
  -rtmpAddr=0.0.0.0:1935 \
  -httpAddr=0.0.0.0:8935 \
  -transcodingOptions=P240p30fps16x9,P360p30fps16x9 \
  # You will need to add your local orchestrator address if you are running off-chain
  -orchAddr=<ORCHESTRATOR_ADDRESSES> #comma separated list of orchestrator addresses
  # Example: -orchAddr=http://192.168.1.100:8935,http://192.168.1.101:8935
  # You can also use a JSON file: -orchAddr=/path/to/orchestrators.json

Replace with publicly available orchestrator addresses.

On-Chain Video Gateway

livepeer -gateway \
  -network arbitrum-one-mainnet \
  # See the on-chain setup guide for more details on these flags
  -ethUrl=<YOUR_RPC_URL> \
  -ethAcctAddr=<YOUR_ETH_ADDRESS> \
  -ethPassword=<YOUR_PASSWORD> \
  -ethKeystorePath=<KEYSTORE_PATH> \
  # Minimum required video flags
  -rtmpAddr=0.0.0.0:1935 \
  -httpAddr=0.0.0.0:8935 \
  -transcodingOptions=P240p30fps16x9,P360p30fps16x9 \
  # Price per unit is required on-chain (see pricing guide)
  -maxPricePerUnit=1000 \
  # You will need to connect to a public orchestrator if you are running onchain
  -orchAddr=<ORCHESTRATOR_ADDRESSES> #comma separated list of orchestrators
  # Example:  -orchAddr=https://orch1.example.com:8935,https://orch2.example.com:8935
  # You can also use a JSON file: -orchAddr=/path/to/orchestrators.json

Livepeer does not currently maintain a list of publicly available Orchestrators. You need to discover them through:

Livepeer CLI: Use livepeer_cli → Option 9: “List registered orchestrators”
Network discovery: The gateway discovers orchestrators from the on-chain registry
Community resources: Check Livepeer community channels or documentation

Jump to the Connect Guide for details on connecting to orchestrators.

OVERVIEW

Gateways for Video Transcoding In traditional video transcoding, the Gateway ingests video streams via RTMP or HTTP, segments them, and distributes transcoding work to Orchestrators

Configuration Methods

You have three ways to configure your Livepeer gateway after installation:

Command-line flags (most common)
Environment variables (prefixed with LP_)
Configuration file (plain text key value format)

Configuration Examples

The below examples show the most common configuration methods.

Transcoding Options JSON

Livepeer supports JSON configuration files for transcoding options through the -transcodingOptions flag. The transcodingOptions.json file lets you precisely control the encoding ladder. This file is a custom configuration file containing an array of rendition objects that defines which renditions (resolutions + bitrates) your Gateway will produce for each incoming stream. It overrides the default built-in ladder (e.g., P240p30fps16x9, etc.).

transcodingOptions.json example

[
  {
    // required
    "bitrate": 1600000,
    "width": 854,
    "height": 480,
    // optional
    "name": "480p0",
    "fps": 0,
    "profile": "h264constrainedhigh",
    "gop": "1"
  },
  {
    // required
    "bitrate": 3000000,
    "width": 1280,
    "height": 720,
    // optional
    "name": "720p0",
    "fps": 0,
    "profile": "h264constrainedhigh",
    "gop": "1"
  },
  {
    // required
    "bitrate": 6500000,
    "width": 1920,
    "height": 1080,
    // optional
    "name": "1080p0",
    "fps": 0,
    "profile": "h264constrainedhigh",
    "gop": "1"
  }
]

Notes

JSON configuration only applies to transcoding options, not other gateway flags
The file must contain valid JSON with the specified structure
All fields are optional except width, height, and bitrate
You can mix JSON configuration with other command-line flags

Modify Config Files

Docker Config (Recommended)
Linux Config
Windows Config

Create the transcodingOptions.json file using the above template.

nano -p /var/lib/docker/volumes/gateway-lpData/_data/transcodingOptions.json

Modify the docker-compose.yml file from the root user’s home directory /root/ and add the following below -pixelsPerUnit=1

-transcodingOptions=/root/.lpData/transcodingOptions.json

Create the transcodingOptions.json file using the above template.

sudo nano /usr/local/bin/lptConfig/transcodingOptions.json

Modify the Linux Service file /etc/systemd/system/livepeer.service and add the following below -pixelsPerUnit=1

-transcodingOptions=/usr/local/bin/lptConfig/transcodingOptions.json \

Create the transcodingOptions.json file using the above template.Open notepad (or your text editor of choice) paste the template above and save the transcodingOptions.json file in the following location.In Windows, %USERNAME% is already a built-in environment variable -> You can use it directly.

C:\Users\%USERNAME%\.lpData\transcodingOptions.json

Modify Windows bat file to include the following command after -pixelsPerUnit=1

-transcodingOptions=C:\Users\%USERNAME%\.lpData\transcodingOptions.json
