OMT WHEP Gateway — Changelog

New

• Multi-language UI — 12 languages: English, Chinese (Simplified), Japanese, Korean, Portuguese (BR), German, Swiss German, Spanish, French, Italian, Turkish, Ukrainian
• Browser auto-detection — language detected from browser settings on first visit
• Language switcher — globe icon in dashboard header for manual language selection; chosen language saved to localStorage
• nftables firewall management — auto-generates firewall rules from channel and settings configuration
• Setup wizard keyboard layout selection — 32 keyboard layouts available during initial setup
• License machine auto-deactivation — automatically deactivates old machine when activation limit is reached

Fixed

• Viewer password no longer triggers a reconnect on every keystroke
• NDI source name parsing corrected
• Accent mark rendering fixed for Spanish and French locales
• Swiss German locale string corrections
• Playwright E2E tests updated for i18n string changes

New

• Per-viewer WebRTC stats — click any viewer count to see a live breakdown of each session: IP, connection type, RTT, packet loss, bytes sent, duration
• Live system monitoring — CPU, RAM, and network bandwidth in the dashboard header with colour-coded thresholds
• Alpha badge — dashboard shows an orange ALPHA tag when running an alpha release
• WHIP output limit — max 2 WHIP outputs per channel (409 Conflict if exceeded)

Fixed

• Start All / Stop All buttons now work correctly with authentication enabled
• Viewer count no longer stuck at 0 — wired SetViewerChangeCallback in main
• ICE candidate type no longer shows unicode garbage — uses .String() method
• bytesSent stats fallback to ICE candidate pair when outbound-rtp not populated
• iOS fullscreen fixed for both WebRTC and WebSocket relay mode

New

• UEFI boot support — ISO now boots on both BIOS and UEFI systems with dual syslinux + GRUB EFI bootloaders
• Version number displayed in the browser dashboard header
• Mobile fullscreen support — fullscreen button now works on iOS Safari

Fixed

• omt_install_to_disk (underscores) now works as alias for omt-install-to-disk
• Removing WHEP password while editing codec no longer prevents channel from starting
• UEFI install-to-disk correctly partitions GPT with EFI System Partition
• Static IP wizard — nmcli connection name parsing fixed
• AV1 frame stutter resolved — uses actual timestamps instead of fixed 33ms
• AV1 audio made optional with -map 0:a?

Improved

• Codec fallback display — shows actual codec in use when configured codec unavailable
• Error toasts in dashboard when channel start/stop fails
• Auto-restart broadcasts status update to all connected browsers

New

• WHIP Output (Alpha) — push channels to remote WHIP ingest endpoints (CDNs, streaming platforms, OME, etc.)
• Per-channel WHIP output configuration from the web UI — endpoint URL, bearer token, enable/disable
• Auto-reconnect with exponential backoff when WHIP endpoints go down
• REST API for WHIP output management (CRUD + start/stop)
• WHIP outputs reuse existing encoded tracks — zero extra CPU/GPU overhead

Improved

• Channel list now sorted alphabetically — no more jumping positions on refresh
• SDP codec negotiation constrained to channel’s actual codec — prevents remote servers picking wrong codec

Fixed

• SVT-AV1 v1.7.0 library symlink fix — ISO was loading system v1.4.1 instead of bundled v1.7.0, breaking AV1 encoding
• FFmpeg rebuilt with clean SVT-AV1 v1.7.0 linkage

Fixed

• AV1 encoding now works correctly — upgraded SVT-AV1 to v1.7.0 (v1.4.1 had broken rate control)
• AV1 WebRTC playback fixed — upgraded Pion WebRTC to v4.2.9 for proper AV1 RTP packetization
• AV1 scene change detection enabled (scd=1) for better quality at lower bitrates
• Keyframe interval options limited to 1–2 seconds (appropriate for live WHEP streaming)
• OMT identity color matrix now correctly converted to BT.709 for SVT-AV1

Fixed

• Install-to-disk now correctly removes all live-boot packages and initramfs hooks, enabling reliable disk boot
• Trial license resets automatically after install-to-disk so the 30-day trial starts fresh on the new system
• High-bitrate streaming stability on streams above 20 Mbps
• libvpx compatibility for VP8/VP9 WebRTC output

Improved

• Setup wizard streamlined — install-to-disk is now a separate CLI command (omt-install-to-disk)
• ISO file size reduced to 903 MB

New

• License activation via Keygen.sh — activate monthly or lifetime licenses from the web UI
• 30-day free trial with full functionality, no license key required
• Stripe-powered checkout with automatic license key delivery via email
• License key recovery page for retrieving keys by email

Improved

• Web UI redesign with cleaner settings panel and license management
• Improved SRT ingest stability on high-bitrate streams

New

• AV1 and VP9 codec support for WebRTC output
• Hardware-accelerated transcoding — Intel QSV, NVIDIA NVENC, AMD AMF
• Multi-viewer: multiple browsers can watch the same channel simultaneously

Improved

• Reduced WebRTC glass-to-glass latency to under 200ms on local networks
• Better automatic codec negotiation with browsers

New

• Web-based dashboard for channel management and monitoring
• REST API for programmatic channel control
• Per-channel configuration — resolution, bitrate, codec settings

Improved

• More reliable OMT source discovery on complex networks
• Lower memory usage when running multiple channels

New

• HEVC (H.265) input support alongside H.264
