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

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

v0.7.1

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)
