• Refactored the project to allow easier integration testing.
• Added contract testing to avoid API client implementation drift with FC2 API.

v1.8.1: Fix concat stream align + mem leak

Caution

Quality upgrade is not working here and will cause a deadlock. Deadlock can be detected by seeing a CANCELED state in the metrics that is too long.

Fixes

• Fix concatenation of multiple streams which are misaligned (video/audio not in the same stream number).
• Fixed memory leak by avoiding calling av_packet_unref when it's not necessary.

Full Changelog: v1.8.0...v1.8.1

v1.8.0: Added metrics and traces

Caution

Quality upgrade is not working here and will cause a deadlock. Deadlock can be detected by seeing a CANCELED state in the metrics that is too long.

New Feature: Added OTEL Tracing, Metrics and Pyroscope

As a wish to seriously improve the performance and memory-safety of fc2-live-dl-go, supports for OTEL and Pyroscope is added.

OTEL and Pyroscope are solutions for YOU to monitor and profile the program. No data is sent to us.

OpenTelemetry

OpenTelemetry provides an API that allows you to collect traces and metrics from the application.

By setting these environment variables:

OTEL_EXPORTER_OTLP_TRACES_ENABLED=true/false
OTEL_EXPORTER_OTLP_METRICS_ENABLED=true/false

You enable push-based telemetry. The telemetry must be send to a OTEL collector like the OTEL Agent or Grafana Alloy.

The parameters of OTEL can be changed using standard environment variables given by the OpenTelemetry project.

Prometheus

In combination with OTEL, we are also exposing the metrics at 0.0.0.0:3000/metrics. This comes included with OTEL.

Pyroscope

In addition to net/http/pprof, github.com/grafana/pyroscope-go/godeltaprof/http/pprof has been added to enable precise continuous profiling via Pyroscope.

The endpoint is still 0.0.0.0:3000/debug/pprof.

Grafana Dashboard

A Grafana Dashboard is now available in the grafana directory

Fixes

• Fixed a memory leak when calling C.CString during concatenation.
• Fixed dts_offset missing free on multiple inputs using arena allocation.
• Ignore empty files and dirs during concat.
• Fixed Windows build and added basic Windows testing.
• Fixed an issue where concatenation of mixed formats didn't work because ignoreSingle was passed.

Other Changes

• Notifications about a new version will now be sent to the user.
• Container images are now signed.
• The quality 3Mbps is now the default. We recommend enabling "quality upgrade".
• The CI is now releasing on GitHub. No more manual releases.
• Removed a goroutine and used idiomatic Go usage of io.Writer to write bytes directly from HTTP request.
• Download lifecycle is now controlled via an error channel instead of the ctx.Done. This allow proper graceful cancellation.
• Added e2e tests by streaming with FFmpeg and do some kool sh- with SSIM and PSNR.
• Added trace log level.
• Bumped Go to 1.22.
