Changelog

All notable changes to this project are documented here.

[v1.8.0] - 2026-08-31

Added

• Next-Gen VitePress documentation portal with SSG sitemap generation, full English & Persian (RTL) dual-language translations, interactive Vue 3 ABR ladder calculator component, and interactive in-browser stream player.
• Added storage package, WithS3Upload() functional option, and --s3-* CLI flags for zero-dependency direct streaming asset uploads to S3, MinIO, and Cloudflare R2 using pure Go AWS SigV4 signer, concurrent worker pool, and optimal MIME/cache headers.
• Added Next-Gen Codec support with WithCodec(), WithHEVC(), WithAV1() options and --codec CLI flag (supporting libsvtav1, libx265, libx264 and hardware encoders).
• Added WithCRF() option and --crf CLI flag for capped-CRF content-aware bitrate optimization.
• Added watermark package, WithWatermark() option, and --watermark CLI flag to dynamically overlay logos/watermarks with customized positioning (top-right, top-left, bottom-right, bottom-left, center), auto-scaling per rendition, and alpha opacity.
• Added encryption package, WithAES128Encryption() option, and --encrypt-aes128 CLI flag for automated cryptographic key generation and HLS AES-128 segment envelope encryption (#EXT-X-KEY:METHOD=AES-128).
• Added subtitles package and WithSubtitles() functional option for WebVTT and SRT subtitle conversion and injection into HLS #EXT-X-MEDIA:TYPE=SUBTITLES and DASH AdaptationSets.
• Added WithNormalizeAudio() option and --normalize-audio CLI flag applying EBU R128 (loudnorm=I=-16:TP=-1.5:LRA=11) broadcast audio volume standardization.
• Added thumbnail package and WithThumbnails() functional option to automatically generate storyboard sprite sheets and standard WebVTT cue files (thumbnails.vtt) for timeline scrubber previews in video players.
• Added preview package and mosaic preview [dir] CLI subcommand launching a local dark-mode HTTP preview player (supporting HLS.js, Dash.js, quality switching, and live stream telemetry).
• Added WithIFrames() functional option and --iframes CLI flag to generate I-frame-only trick-play playlists (#EXT-X-I-FRAMES-ONLY) for HLS.
• Added docs/ROADMAP_PROGRESS.md to track implementation progress across all roadmap phases.

Fixed

• Fixed DASH conflicting stream aspect ratios error on portrait and non-standard videos by explicitly configuring DAR (setdar) across all ladder rungs in the filter complex.
• Fixed HLS live profile failure caused by unrecognized -hls_part_size option in modern FFmpeg versions.
• Removed deprecated -vsync vfr option from thumbnail generation command to ensure compatibility with modern FFmpeg (v7, v8, v9).

[v1.7.3] - 2026-08-25

Added

• Added GoReleaser configuration (.goreleaser.yaml) and GitHub Actions release workflow (.github/workflows/release.yml) for automated multi-platform cross-compilation (Linux, macOS, Windows on amd64 and arm64) and Release Asset generation on tag push.
• Added dynamic version injection support via ldflags in cmd/mosaic.

[v1.7.2] - 2026-08-25

Fixed

• Fixed real-time progress reporting by accumulating FFmpeg key-value progress lines into complete blocks (StreamProgress) emitted at progress=continue and progress=end. Prevents partial single-line emission where metrics (out_time, speed, bitrate, Percentage) appeared empty.
• Preserved last known valid metrics when FFmpeg emits N/A at progress=end, ensuring final percentage accurately reflects 100.0%.

[v1.7.1] - 2026-08-25

Fixed

• Fixed file name too long error when normalizing orientation on complex remote URLs with URL-encoded query strings (e.g. proxy URLs, signed URLs, CDN tokens). normalizedInputExt now cleanly parses URL paths and restricts intermediate file extensions to safe media types.

[v1.7.0] - 2026-08-25

Added

• Real-time progress percentage calculation in ProgressInfo.Percentage computed from probed media duration and encoded timestamps.
• Added Duration metadata field to probe.VideoInfo.
• Added BFrames configuration to config.Profile (defaults to 0) and WithBFrames(n) functional option.
• Added optional WithScaleBitrateWithFPS() option to dynamically adjust bitrate caps for high-framerate (>30 FPS) content.
• Added AddSequentialResponse and queue support to executor.MockCommandExecutor for multi-step mock testing.
• Added maintainer contact email and GitHub Security Advisories link in SECURITY.md.

Changed

• Unified DASH encoding pipeline to use single-pass filter_complex (split -> scale -> setsar=1) matching HLS behavior.
• Added -bf flag to DASH video stream arguments.
• Enforced golangci-lint run as a mandatory pre-commit contract across all documentation.
