livepeer/go-livepeer v0.5.9 on GitHub

Summary

This release includes support for multi-orchestrator node setups, more robust winning ticket management for orchestrators, a number of new transcoding features (fractional FPS, H264 profiles, GOP length) and a few updates/bug fixes.

Thanks to everyone that submitted bug reports and assisted in testing!

Features

Broadcaster

Set orchestrator request timeout based on segment duration (#1477)
- This feature gives broadcasters more flexibility in sending variable duration segments for transcoding. The current duration cap is 5 minutes
Add support for requesting fractional FPS for transcoding (#1525 livepeer/lpms#192)
- See the docs for information on specifying a fractional FPS using a webhook
Add support for requesting H264 profiles for transcoding (#1542 livepeer/lpms#196)
- See the docs for information on specifying H264 profiles using a webhook
Add support for requesting a GOP length for transcoding
- See the docs for information on specifying GOP lengths using a webhook (#1551 livepeer/lpms#198)
Export deposit/reserve metrics via Prometheus (#1541)
- This feature will enable Prometheus integrations to leverage deposit/reserve data for monitoring/alerting

Orchestrator

Allow multiple orchestrator nodes using their own addresses to accept payments on behalf of a single on-chain registered address (#1476)
- See the docs for information on running multiple orchestrator nodes
Use a database for more robust winning ticket storage, submission and retries (#1493)
Allow orchestrator nodes to submit winning tickets to a node running a ticket redemption service (#1495 #1545 #1521)
- This feature allows orchestrator nodes to be run with Ethereum addresses without any funds since the orchestrator node will not need to submit any transactions
- See the docs for information on how the ticket redemption service works
- See the multi orchestrator docs for information on how to run multiple orchestrator nodes with a ticket redemption service
Set remote transcoder request timeout based on segment duration (#1511)
- This feature gives orchestrators that use remote transcoders more flexibility in transcoding variable duration segments
Add support for transcoding with fractional FPS (#1525 livepeer/lpms#192)
Add support for transcoding with H264 profiles (#1542 livepeer/lpms#196)
Add support for transcoding with a set GOP length (#1551 livepeer/lpms#198)
Add a -reward flag that can be used to explicitly enable/disable the reward service which automatically triggers reward calls (to mint LPT rewards) each round that a node is active
- See the docs for information on -reward flag usage
Clear the stored ticket sender nonces tracked per broadcaster after an expiration time which avoids continuous memory usage growth as the orchestrator receives tickets from different broadcasters (#1526)

Bug Fixes

Broadcaster

Fix a bug where the fee estimated for a segment when using FPS passthrough (i.e. use the same FPS as the source for the transcoded rendition) was 0 (#1508)

Orchestrator

Fix a bug where transcoders were unable to handle segments with a single frame (#1502 livepeer/lpms#189)
Fix a bug where the transcoder load balancing cost estimated for a segment when using FPS passthrough (i.e. use the same FPS as the source for the transcoded rendition) was 0 (#1508)
Fix a bug where a winning ticket would never be redeemed if an initial redemption transaction failed due to an uninitialized round (#1493)
Update the gas cost estimate for a ticket redemption transaction to more accurately reflect the actual gas cost for the transaction (#1553)
