The livepeer binary in go-livepeer has a number of configurable options. You can set your configuration using command-line flags, environment variables, or a config file.

A comprehensive list of options can be found below. They are sourced and regularly updated from this file. The go-livepeer developer docs also contain instructions for using flags to enable certain functionality in livepeer.

​
Options

​
Configuration

  • config: Path to config file.

​
Network and Addresses

  • network: Network to connect to. Default offchain

  • rtmpAddr: Address to bind for RTMP commands. Default 127.0.0.1:+RtmpPort

  • cliAddr: Address to bind for CLI commands. Default 127.0.0.1:+CliPort

  • httpAddr: Address to bind for HTTP commands. No default

  • serviceAddr: Orchestrator only. Overrides the on-chain serviceURI that gateways can use to contact this node; may be an IP or hostname. No default

  • orchAddr: Orchestrator to connect to as a standalone transcoder. No default.

  • verifierURL: URL of the verifier to use. No default.

  • verifierPath: Path to verifier shared volume. No default.

  • localVerify: Set to true to enable local verification i.e. pixel count and signature verification. Default true. However, if you are running in offchain mode, this will be set to false.

  • httpIngest: Set to true to enable HTTP ingest. Default true. However, if (1) you do not provide a value, (2) you provide a non-local URL for httpAddr, and (3) you do not provide an authWebhookURL, this will be set to false.

​
Onchain

  • ethAcctAddr: Existing Eth account address. For use when multiple ETH accounts exist in the keystore directory

  • ethPassword: Password for existing Eth account address or path to file

  • ethKeystorePath: Path to ETH keystore directory or keyfile. If keyfile, overrides -ethAcctAddr and uses parent directory

  • ethUrl: EVM-compatible chain node JSON-RPC URL. No default

  • txTimeout: Amount of time (ms) to wait for a transaction to confirm before timing out. Default 300000 (5 mins)

  • maxTxReplacements: Number of times to automatically replace pending transactions. Default 1

  • gasLimit: Gas limit for ETH transaction. Default 0

  • minGasPrice: Minimum gas price (priority fee + base fee) for ETH transactions in wei, 10 Gwei = 10000000000. If not set, this will be the network’s default min gas fee.

  • maxGasPrice: Maximum gas price (priority fee + base fee) for ETH transactions in wei, 40 Gwei = 40000000000. Default 0

  • ethController: Protocol smart contract address. No default

  • initializeRound: Set to true if running as a transcoder and the node should automatically initialize new rounds. Default false.

  • ticketEV: The expected value for PM tickets. Default 1000000000000

  • maxTicketEV: The maximum acceptable expected value for PM tickets. Default 3000000000000

  • depositMultiplier: The deposit multiplier used to determine max acceptable faceValue for PM tickets. Default 1

  • pricePerUnit: The price per ‘pixelsPerUnit’ amount pixels. Must be greater than 0. Error if not set.

  • maxPricePerUnit: The maximum transcoding price (in wei) per ‘pixelsPerUnit’ a gateway is willing to accept. If not set explicitly, gateway is willing to accept ANY price. Default 0

  • pixelsPerUnit: Amount of pixels per unit. Set to ’> 1’ to have smaller price granularity than 1 wei / pixel. Default 1

  • pricePerGateway: json list of price per gateway or path to json config file. Example: {"gateways":[{"ethaddress":"address1","priceperunit":1000,"pixelsperunit":1},{"ethaddress":"address2","priceperunit":1200,"pixelsperunit":1}]}

  • autoAdjustPrice: Enable/disable automatic price adjustments based on the overhead for redeeming tickets. Default true

  • blockPollingInterval: Interval in seconds at which different blockchain event services poll for blocks. Default 5

  • redeemer: Set to true to run a ticket redemption service. Default false

  • redeemerAddr: URL of the ticket redemption service to use. No default

  • reward: Set to true to run a reward service. If you do not want to automatically call reward(), you need to explicitly set this to false for any node that’s registered onchain. Otherwise, it will default to true.

  • monitor: Set to true to send performance metrics. Default false

  • version: Print out the version. Default false

  • v: Log verbosity - . No default
