New Features:

1. Added NDI HB protocol conversion function.
2. Added configurable reconnection response time settings for video sources.

Fixes:

1. Resolved the issue where latency increased cumulatively over time during RTSP output.
2. Fixed the issue of discontinuous and stuttering audio streams in NDI HB output.
3. Fixed the issue where NDI HX output failed to automatically resume after the video source reconnected following a stream interruption.
4. Resolved the A/V synchronization issue caused by adjusting the output frame rate.
5. Fixed the occasional green screen output and audio stuttering issues when converting to NDI HX.

Optimizations:

1. Optimized the operational stability of the software.

Notes:

1. Format Conversion: Supports a maximum resolution of 4K at 30fps (4Kp30);
2. After the stream status of the video source device changes, the video source status on the FMG-400 side will take approximately 10 seconds to update;
3. The NDI HX output from protocol conversion has no sub-stream;
4. During output, if you modify the audio sample rate, number of audio channels, or audio encoding format of the video source, the output will not be updated synchronously. You need to restart the output service;
5. After adding an output, if you then bind an NDI HB video source, you must manually enable the audio and video transcoding switch;
6. If the output status is abnormal, shut down the output service. After the video source shows "disconnected" and the output shows "not started", restart the service to restore the output;

Release Date: 2025-11-21 Version: 1.03

Core Functions:

1. Comprehensive Protocol and Encoding Format Support Input/output streaming protocols: NDI®|High Bandwidth, NDI®|HX2/3, SRT, RTMP, RTSP, RTP, TS-over-UDP, HLS. Video encoding: H.264/AVC, H.265/HEVC, SpeedHQ (NDI®|High Bandwidth). Audio encoding: AAC, PCM, G.711 (supports extension for additional codecs).
2. Flexible Media Processing and Format Conversion Capabilities Supports configuration of video encoding format, resolution, frame rate, bitrate, as well as audio format, sample rate, channel count, and bitrate conversion. Enables upscaling/downscaling of resolution and frame rate. (Note: Limited by maximum processing capacity, only downscaling is supported for 4K videos.)
3. Free Protocol Conversion and High-Concurrency Distribution The FMG-400 can flexibly convert one input media protocol to one or multiple output protocols. For example, it can convert an input SRT stream to both NDI HB and NDI HX for simultaneous output; similarly, it supports SRT input-to-SRT output, enabling distribution to up to 50 concurrent connections.
4. Fast “Source-Destination” Switching Based on Crosspoint Mode The FMG-400 offers a crosspoint control mode similar to a “video matrix.” Operators can complete source-to-destination video switching with quick clicks on the crosspoint control panel, simplifying the signal switching and scheduling process.
5. Localized Streaming Conversion Output for Kiloview P-Series 4G/5G Bonding Encoders The FMG-400 provides scalable bonding stream reception and conversion services for Kiloview P-series wireless encoders when deployed inside the RF02 chassis.

Notes:

1. Format Conversion: Supports a maximum resolution of 4K at 30fps (4Kp30);
2. After the stream status of the video source device changes, the video source status on the FMG-400 side will take approximately 10 seconds to update;
3. The scenario of converting NDI HB to NDI HB is not supported;
4. The NDI HX output from protocol conversion has no sub-stream;
5. During output, if you modify the audio sample rate, number of audio channels, or audio encoding format of the video source, the output will not be updated synchronously. You need to restart the output service;
6. After adding an output, if you then bind an NDI HB video source, you must manually enable the audio and video transcoding switch;
7. If the output status is abnormal, shut down the output service. After the video source shows “disconnected” and the output shows “not started”, restart the service to restore the output。
