Summary
This release includes a few important bug fixes as well as some improvements to the consistency and reliability of the transcoding workflow between broadcasters and orchestrators. We strongly recommend that orchestrator operators upgrade to this version to access the bug fixes.
Thanks to everyone that submitted bug reports and assisted in testing!
Features ⚒
General
- Support multiple segments in flight on both broadcasters and orchestrators (#1735 #1749)
- The broadcaster will support multiple segments in flight for an orchestrator as long as the oldest segment is within the maximum in-flight time requirement which is currently set to the duration of the segment
Broadcaster
- Record metrics when using the stream recording feature (#1710)
- Record a metric for the number of swaps to different orchestrators for a stream (#1735)
- Classify additional segment upload errors as timeouts when recording upload error metrics (#1717)
- Reduce orchestrator discovery related logs by removing redundant logs and using the DEBUG logging level for certain logs (#1732)
- Treat no keyframe errors from orchestrators as non-retryable errors (#1745)
Bug Fixes 🐞
Broadcaster
- Fix 500 errors caused by concurrent HTTP push sessions that use the same internal manifestID (provided by a webhook) (#1706)
Orchestrator
- Ensure that advertised ticket face values cover the estimated redemption tx cost (#1751)
Transcoder
- Fix an issue where transcoding could get stuck if a segment without keyframes is received. Now, a no keyframe error is returned in stead (#1745 livepeer/lpms#220)
- Fix an issue where Nvidia transcoding could get stuck if a segment contains invalid packets that trigger a Nvidia driver/CUDA error (#1753 livepeer/lpms#223)
