Release Date: 2026-07-08 Version: 2.45

New Features:

• NDI 6.3 SDK Upgrade and Enhanced NDI Monitoring Capabilities：
  • Encoder: Added support for NDI Sender Advertiser and Sender Monitoring API, allowing third-party platforms to discover and monitor the status of encoder sender instances.
  • Decoder: Added support for NDI Receiver Monitoring API, along with the following new features:
    • Added Allow Receiver Advertising and Allow Remote Receiver Control options.
    • Decoding channels can now be discovered and monitored by the NDI Discovery Server as NDI Receivers, and support remote switching or closing of the currently decoded NDI source.

Encoder Features

• N50/N60: Added 8-channel audio support
  • In encoding mode, an 8-channel audio option has been added for audio channel configuration, supporting more professional audio input and multi-channel encoding scenarios.
• N50/N60: Added WHIP streaming protocol support
  • Supports streaming via the WHIP protocol, improving compatibility with WebRTC platforms and related workflows.
• N50/N60: Added NDI High Bandwidth interlaced source processing
  • Supports processing of interlaced input sources. Users can choose to keep 1080i interlaced output or convert it to 1080p progressive output according to actual requirements.
  • NDI High Bandwidth and NDI HX share the same deinterlacing algorithm.
• N50/N60: Added custom no-signal image output when no input signal is detected, applicable to all encoding protocols
  • When no input signal is detected on the encoder side, the device can output a user-defined no-signal image.
• N60: Added SEI timecode parameter configuration in encoding mode
  • Added SEI timecode parameter settings for NDI HX and NetStream in the N60 WebUI encoding video settings.
  • Users can configure the timecode embedding method based on their workflow requirements, improving compatibility with post-production, synchronization verification, and professional video workflows.

Decoder Features

• N50/N60: Added support for decoding video streams with B-frames
  • Improves decoding compatibility for video streams containing B-frames.
• N50/N60: Added support for decoding video sources with multiple audio tracks
  • Supports decoding video sources with multiple audio tracks.
  • Up to 16 audio channels can be decoded, and output audio mapping supports 16-to-8 channel selection.
• N50/N60: Added custom no-signal image output when the source is interrupted
  • When the decoded source is interrupted or no valid signal is available, the device can output a user-defined no-signal image.
• N50: Added output frame rate configuration and frame rate scaling in decoding mode
  • Added frame rate configuration capability in the N50 decoding output settings.
  • Supports output-side frame rate configuration and scaling, improving compatibility with different display devices and output formats.

Device Security Enhancement

• Added random SSL certificate generation mechanism
  • The device now supports generating a unique SSL certificate during first startup or initialization.
  • This avoids multiple devices sharing the same SSL certificate, improves device communication security, and reduces security risks related to TLS/SSL certificate uniqueness.

Front Panel Display Enhancement

• Added input source information display on the front panel
  • Optimized the display logic for HDMI, SDI, AUDIO, and other source information on the N50/N60 front panel.
  • The current input source information can now be displayed, allowing users to quickly check the input status on site.

Optimizations:

• Encoding Performance and Video Stability Improvements
  • Optimized video jitter issues when encoding NDI HX interlaced formats.
  • Optimized insufficient frame rate issues when encoding 4096×2160p60 H.265.
  • Optimized frame drop issues when encoding 3840×2160p60 H.264 4:2:2 8-bit and H.264 4:2:0 10-bit.
  • Optimized deinterlacing processing logic to improve video stability when encoding and playing interlaced video sources.
  • Optimized the overall user experience and operation response speed on the encoder side.
• Audio/Video Synchronization Improvements
  • Optimized audio and video timestamp processing logic on the encoder side to improve A/V synchronization in encoded streams.
  • Optimized the issue where audio and video may gradually become out of sync after long-term operation, improving stability in long-duration live streaming, broadcasting, and monitoring scenarios.
  • Optimized A/V synchronization and preview stability when input signals are plugged/unplugged or when the input source is unstable, reducing issues such as preview black screen, real-time bitrate showing 0, and stream pulling failures.
• Network Streaming and Pulling Improvements
  • Optimized RTSP, SRT, RTMP, and other network streaming performance to improve streaming stability and pulling compatibility.
  • Optimized RTMP streaming latency, reducing delay by approximately 2 seconds compared with the previous version.
  • Optimized RTSP connection establishment, stream startup, and first stream pulling after device reboot, reducing startup failures or pulling exceptions caused by waiting for IDR frames, queue pre-alignment, or abnormal reboot status.
  • Optimized the cache strategy when SRT Listener shares live streaming, improving playback stability in complex network environments.
  • Optimized A/V synchronization performance during long-term SRT operation.
• Recording Improvements
  • Multi-track recording is now used by default.
  • MP4 / MOV audio now uses a 4-track layout by default, namely 4 stereo pairs, improving compatibility with multi-channel audio recording and post-production workflows.
• Signal Detection and Status Handling Improvements
  • Optimized input video signal stability detection logic, improving handling stability in no-signal, signal recovery, and resolution switching scenarios.
  • Optimized system processing logic for scenarios such as input source plugging/unplugging and intermittent input signals.
• Other Improvements: Several other improvements to user experience and system stability.

Bug Fixes:

• Fixed an issue where stream pulling and playback could stutter in SRT Rendezvous mode, improving decoding stability in this mode.

• Fixed a compatibility issue that could occur when N50 receives an input source without ST352 Payload ID.

• Fixed an issue where the WebUI page did not automatically refresh or update the status in time after the device rebooted successfully.

• Fixed several other known issues.
