Version 1.5.0

Changelog

Added

• Allow passing projectID for URL requests (#429)
• Introduce linter configuration shared with egress, fixing a wide range of issues including unused params, deprecated APIs, unexported return types, typos, a TrimLeft bug, and a mutex-copy bug in a proto message (#425)
• Add segment start to adjusted buffer PTS; simplify event probe (#398)
• Log segment events to help diagnose non-~0s segments that could push buffer PTSs outside the segment range (#397)
• Observe buffer processing latency and expose it as a Prometheus metric (#392)
• Gate excess pre-roll buffered media to reduce end-to-end latency (#386)
• Ingress metrics (#383)
• Pass WHIP through to the SFU directly, with a config option to choose between SFU and native paths; includes WHIP HTTP header handling and RTC closing notify support (#372)
• IngressID and ResourceID attributes on ingress participants (#344)
• Custom HandlerLogger implementation (#339)
• Media watchdog at the tail of the pipeline (input of the Go SDK) to close the ingress if no media is received on any track for 1 minute — needed for cases like SRT where GStreamer may retry connecting forever without emitting any failure event (#334)
• Backpressure-aware synchronizer: monitor a queue between the appsink and the Go SDK; if it grows past 2 buffers, reduce the synchronizer wait time in 10ms steps until the queue shortens. Addresses a deadlock case in SRT where the reference/wait time was only ever increased, causing the input buffer to fill to its max. Disabled for HLS, where back pressure at the output is expected. (#337)
• Announce out-of-network splice events as participant attributes (derived from SCTE-35 tables in MPEG-TS streams, e.g. SRT). Implemented by monitoring SCTE-35-related GStreamer events pushed down the pipeline — message-bus-based events lack pipeline-timebase timing and the MPEG-TS demuxer doesn't expose the needed info to regenerate timestamps. Relies on a forked go-gst for now. (#326)
• Reject ingress if the Enabled flag is false (#319)

Changed

• Log caps existence when connecting to caps notifier (#431)
• Replace deprecated io/ioutil.ReadFile with os.ReadFile for config loading (#424)
• Refactor ingress handler RPC server: remove PSRPC support from the ingress handler and move the full PSRPC server implementation into the server process; introduce a StateNotifier family of objects for injecting state-update behavior; add an (initially empty) ProjectID field to StateNotifier calls (#413)
• Only report packet loss if trackStats is set (#401)
• Update GStreamer to 1.26.7 (#396)
• Update Go to 1.25 (#388)
• Use FeatureFlags from GetIngressInfoResponse or StartIngressRequest; rename the SFUTranscodingBypassedWHIP config option to WHIPProxyEnabled (#382)
• Fix the format of the logging field in the sample config (#377)
• Delay deregistering the WHIP RPC handler to avoid SFU notify warnings (#373)
• Switch to the livekit/gst-go fork of go-gst (#367)
• Update CLI to urfave/cli/v3 (#364)
• Set logging parameters on Pion; ignore Pion ICE candidate warning (#348)
• Throttle "too slow" logs (#340)
• Disable output queue-length monitoring for RTMP and WHIP (#338)
• Disable max-buffer limit on URL input queue; log SRT stats every minute (#335)
• Initialize URL ingress state with BUFFERING when created directly by the Ingress server (#333)
• Use logger utilities in ingress (#332)
• Remove actions/cache from workflows/build.yaml — the cloud-ingress build uses Docker, so caching Go modules from the host is pointless (#325)

Fixed

• Fix int cast flagged by Copilot (#416)
• Ensure the logger is initialized before the output registers for EOS, preventing a race that could cause a panic if EOS arrived during creation (#415)
• Ignore all errors from writeSample once the output is already closed — not just EOF — so hitting the shutdown timeout no longer sets pipelineError and flips the pipeline to a failed state (#412)
• Do not treat io.EOF as a pipeline error during shutdown; handleSample() keeps returning FlowOK while samples are dropped so GStreamer can drain its queues without interpreting early FlowEOS as a mid-stream failure (#411)
• Make sure EOS reaches sinks: signal "EOS seen on source" out-of-band so the output can decide to wait briefly for remaining data (or cancel), preventing the pipeline from freezing when the appsink thread is stuck on a blocking push (#408)
• Safer fallback logic for latency reduction: if A/V arrival rates don't stabilize, skip applying offsets entirely instead of taking the current max of calculated offsets (#406)
• Initialize logger before the handler starts (#399)
• Fix superfluous response.WriteHeader call: only send a status code if data hasn't already been written (an implicit 200) (#395)
• Make sure an ingress session is terminated when sending on the app source doesn't cause the pipeline to emit an EOS event (#379)
• Propagate sink errors when the input error is (generic, consequential) context.Canceled (#381)
• Fix "disonnected" → "disconnected" typo in error messages (#360)
• Fix flaky/broken tests (#378, #374)
