v0.7.9

September 10th 2024

What's Changed

This release includes metadata embedded into transcoded segments (transcoder version and orchestrator onchain address), as well as a number of other gateway-side fixes and improvements.

Features ⚒

Orchestrator

• #3156 validate -serviceAddr on startup and cli handler by @eliteprox
• #3165 Add node version and orch addr to transcoded metadata by @j0sh

Broadcaster

• #3158 Add a metric tag for Orchestrator version by @mjh1

Bug Fixes 🐞

Broadcaster

• #3164 Fix media compatibility check by @j0sh
• #3166 Clean up inactive sessions by @leszko
• #3086 Clear known sessions with inadequate latency scores by @leszko

CI/CD

• #3162 build.yaml: Skip upload step raising an error for PR from forks by @hjpotter92

Full Changelog: v0.7.8...v0.7.9

v0.7.8

The release also includes v0.7.7; which could not get published to github release due to bug in our CI/CD.

What's Changed

• Add flag 'ignoreMaxPriceIfNeeded' by @leszko in #3127
• build.yaml: Fix extraction of artifacts when preparing for release by @hjpotter92 in #3146

v0.7.7

This release includes a new -hevcDecoding flag for transcoders to configure HEVC decoding. If the flag is omitted, the default behavior on GPUs is unchanged, which is to auto-detect HEVC decoding support at transcoder start-up. Transcoders can disable HEVC decoding on GPUs if there is an issue with HEVC jobs via -hevcDecoding=false. CPU transcoders now have HEVC decoding disabled by default since processing HEVC jobs is CPU-heavy, but this can be enabled by setting the -hevcDecoding flag.

The transcoder now support mid-stream input rotations, rather than crashing or outputting cropped video as it did before.

Breaking Changes 🚨🚨

• #3119 CPU transcoders no longer decode HEVC or VP9 by default

Transcoder

• #3119 Add -hevcDecoding flag to toggle HEVC decoding

Bug Fixes 🐞

Transcoder

• #418 lpms: Fix CUVID crash on resolution change
• #417 lpms: Clamp resolutions in filter expression
• #416 lpms: Rescale DTS better during FPS passthrough

Full Changelog: v0.7.7...v0.7.8

v0.7.6

What's Changed

This release brings in:

• Update LPMS to ffmpeg 7.0.1 . If building from source, ffmpeg need to be re-built in a clean home directory via ./install_ffmpeg.sh by @j0sh in livepeer/lpms#406
• The -broadcaster and -pricePerBroadcaster CLI options are deprecated in favor of -gateway and -pricePerGateway by @rickstaa in #3053 and #3056
• A new /healthz endpoint on the video HTTP port by @leszko in #3095
• Various fixes and improvements

New Contributors

• @linghuying made their first contribution in #3070
• @tongjicoder made their first contribution in #3081

Full Changelog: v0.7.5...v0.7.6

v0.7.5

May 14th 2024

This release brings a fix in the transcoding layer for WebRTC streams. The fix is followed by a change in the B<>O<>T protocol to include the information about the go-livepeer version, which effectively gives Broadcaster an option to exclude from the selection process those O/Ts that have not updated to a certain go-livepeer version.

• Fix transcoding of WebRTC streams by @j0sh in livepeer/lpms#393
• Create an option to filter Os by min livepeer version used by @leszko in #3050
• Initialize round by any B/O who has the initializeRound flag set to true by @leszko in #3029
• Changes in the maxPrice and conversion rate by @victorges in #2994 #2995 #2999

Full Changelog: v0.7.4...v0.7.5

v0.7.4

April 2nd 2024

This release is related to the Revert "Bump ffmpeg version and nv-codec-headers" (#2989).

Full Changelog: v0.7.3...v0.7.4

v0.7.3

March 29th 2024

This release includes the price conversion feature and livepeer dependencies (CUDA, ffmpeg) upgrades.

• Allow specifying pricePerUnit in currencies other than wei (e.g. USD) by @victorges in #2972 and #2981
• Bump ffmpeg version and nv-codec-headers by @thomshutt in #2973
• Update CUDA build version from 11.7.1 to 12.0.0 by @leszko in #2978

Full Changelog: v0.7.2...v0.7.3

v0.7.2

January 29th 2024

This update includes a number of quality of life improvements across Broadcasters and Orchestrators, notably:

• Being more lenient in certain cases to avoid unnecessary Orchestrator Swaps by @leszko in #2885
• Avoiding GetOrchestrator slowness when PM Sender data is not cached by @stronk-dev in #2849
• Fix a vulnerability that allowed unfair mid-stream price switching by @leszko in #2892
• Orchestrator: add flag to skip the availability check on startup by @stronk-dev in #2928
• Add '-maxTotalEV' flag by @leszko in #2897
• Correctly initializing default metrics to 0 by @papabear99 in #2888
• A number of logging and metrics improvements by @papabear99, @ad-astra-video, @rickstaa, @stronk-dev and @thomshutt
• Livepeer CLI improvements from @eliteprox, @rickstaa and @thomshutt

Full Changelog: v0.7.1...v0.7.2

v0.7.1

October 10th 2023

This update enhances the quality of transcoding. The Broadcaster now has the ability to request the HW session to be reinitialized. This feature is necessary for videos that have varying video parameters between segments, such as a changed resolution.

Changes:

• #2882 Add parameter to force HW Session Reinit (@leszko)
• #2884 Detect resolution change and reinit hw session (@leszko)
• #2883 Skip transcoding when empty profiles were sent to B (@leszko)

v0.7.0

October 4th 2023

This release brings two important updates: first, we have enhanced the quality of transcoding for orchestrators. Additionally, we have implemented a new selection algorithm for the broadcaster.

The go-livepeer release includes 2 Linux binaries: Standard and GPU. The Standard binary is suitable for use cases that do not require GPU transcoding. The GPU requires the CUDA SDK and supports GPU transcoding.

Other notable changes:

• #2781 Add automatic session limit
• #2850 Update default ports

Full Changelog

v0.6.0

August 8th 2023

This release adds a configurable blocklist allowing B nodes to include or exclude specific Orchestrator addresses according to their requirements. For example, Broadcasters using only VOD may prioritize price over performance; Broadcasters who run their own Os may choose to exclude all addresses but their own.

The blocklist is a first step towards an open marketplace for selection configuration, and we expect all sorts of configurations to become available for different use cases.

The hosted gateway’s current policy can be viewed here.

Other notable changes:

• #2821 Bump nvidia/cuda base version for docker builds
• #2758 Accept only active Os to receive traffic and redeem tickets
• #2775 Reduce number of ETH RPC calls during block polling
• #2759 Parse keystore address without 0x prefix, fix parse error logging
