FN-50 Firmware Download(Latest) Download Version: 1.25 Size: 290 MB Release Date: 2026-07-21 Version: 1.25 New Features: 1.NDI 6.3 SDK Upgrade and Enhanced NDI Monitoring Capabilities： (1)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. (2)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. 2.Encoder Features (1)FN-50/FN-60: 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. (2)FN-50/FN-60: Added WHIP streaming protocol support Supports streaming via the WHIP protocol, improving compatibility with WebRTC platforms and related workflows. (3)FN-50/FN-60: 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. (4)FN-50/FN-60: 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. (5)FN-60: Added SEI timecode parameter configuration in encoding mode Added SEI timecode parameter settings for NDI HX and NetStream in the FN-60 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. 3.Decoder Features (1)FN-50/FN-60: Added support for decoding video streams with B-frames Improves decoding compatibility for video streams containing B-frames. (2)FN-50/FN-60: 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. (3)FN-50/FN-60: 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. (4)FN-50: Added output frame rate configuration and frame rate scaling in decoding mode Added frame rate configuration capability in the FN-50 decoding output settings. Supports output-side frame rate configuration and scaling, improving compatibility with different display devices and output formats. 4.Device Security Enhancement (1)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. Optimizations: 1.Encoding Performance and Video Stability Improvements (1)Optimized video jitter issues when encoding NDI HX interlaced formats. (2)Optimized insufficient frame rate issues when encoding 4096×2160p60 H.265. (3)Optimized frame drop issues when encoding 3840×2160p60 H.264 4:2:2 8-bit and H.264 4:2:0 10-bit. (4)Optimized deinterlacing processing logic to improve video stability when encoding and playing interlaced video sources. (5)Optimized the overall user experience and operation response speed on the encoder side. 2.Audio/Video Synchronization Improvements (1)Optimized audio and video timestamp processing logic on the encoder side to improve A/V synchronization in encoded streams. (2)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. (3)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. 3.Network Streaming and Pulling Improvements (1)Optimized RTSP, SRT, RTMP, and other network streaming performance to improve streaming stability and pulling compatibility. (2)Optimized RTMP streaming latency, reducing delay by approximately 2 seconds compared with the previous version. (3)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. (4)Optimized the cache strategy when SRT Listener shares live streaming, improving playback stability in complex network environments. (5)Optimized A/V synchronization performance during long-term SRT operation. 4.Recording Improvements (1)Multi-track recording is now used by default. (2)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. 5.Signal Detection and Status Handling Improvements (1)Optimized input video signal stability detection logic, improving handling stability in no-signal, signal recovery, and resolution switching scenarios. (2)Optimized system processing logic for scenarios such as input source plugging/unplugging and intermittent input signals. 6.Other Improvements: Several other improvements to user experience and system stability. Bug Fixes: 1.Fixed an issue where stream pulling and playback could stutter in SRT Rendezvous mode, improving decoding stability in this mode. 2.Fixed a compatibility issue that could occur when FN-50 receives an input source without ST352 Payload ID. 3.Fixed an issue where the WebUI page did not automatically refresh or update the status in time after the device rebooted successfully. 4.Fixed several other known issues.
