Improvements:

• NDI source improvements:

  • PCR based on audio
  • Limit AV diff to [-250-250] ms
  • Limit audio coming too fast
  • Extended logs and small improvements for NDI input

• Show NTP and PTP service status

• BugFix: LT-5470: PTS calculation on framerate conversion UCs

• BugFix: Avoid drops caused by violating latency constraints from NDI source (use only positive PTS offsets)

• BugFix: NDI source getting stuck when scan rate changes

• BugFix: LT-5499, LT-5532: Fix multiple AAC enc/dec PTS related issues

• BugFix: Correct index 503 page for docker deployment

Improvements:

• Total output bitrate setting automatic by default
• LT-5483: Set default logging to journal and limit its size
• BugFix: LT-5520: Missing audio prevents pipeline from autoreconfiguring (output pairs and quad cases)

Improvements:

• BugFix: LT-5527: Move back to older AAC decoder for AAC non-HE to fix decoding RTMP input audio

Improvements:

• BugFix: LT-5520: Missing audio prevents pipeline from autoreconfiguring

New Features

• New TS muxer for larger compatibility and robustness, used as default

• Latency addition option exposed in UI

• Automatic total bitrate when 0 is used

• Video passthrough (with bitrate=0) for any MPEG-TS video

• AAC-HE on input and output, v2 for stereo

• Different clocking mechanisms on NDI input available in UI (free-run, framesync, avsync)

• PSF encoding for h264 and h265

• Show status of SDI genlock in UI

• [experimental] video pass-through for RTMP output

Improvements:

• Improve latency of NVENC h264 workflows when used in LL mode expecting zero B-frames

• Codec selector for pairs and quads mode of autoreconfiguration

• Upgrade to JAVA 21 and Spring Boot to 2.7.18

• Low-complexity framerate conversion modes in settings.ini

New Features

• Downgrade nvEncodeAPI.h to version 11.1.5 (used for H.264 encoding)

• Update nv_codec_headers for FFMpeg to 11.1.5.3 (used for H.265 encoding)

New Features

• Add possibility to configure SRT bonding (redundancy) for SRT caller

• It's possible to specify multiple NDI discovery servers instead of just one

• It's possible to adjust NDI codec quality using the NDI_CODEC_SHQ_QUALITY variable in settings.ini. This requires the ADVANCED_NDI license item. It's not available for BridgeLive.

Bugfixes:

• BugFix: Enable processing of MPTS where PIDs of PMTs of different programs are equal
• BugFix: Correctly use input/output NIC selected by user

UX/UI Improvements

• UI: Improve Dashboard stream statistics

New Features

• Add support for the DolbyE passthrough for the SDI and the transport stream IN/OUT.

Bugfixes:

• Bugfix: The SDI and NDI audio output is fixed.

UX/UI Improvements

• UI: SRT Latency field is presented in UI again.

New Features

• Add support for insertion of timestamp into SEI messages of H264 & H265 (supported with TS, NDI and SDI inputs)
• Added the /api/system/hostname REST endpoint.

Bugfixes:

• Bugfix: latency calculations
• Bugfix: New TS Muxer (experimental): multiple bugfixes
• Bugfix: [LT-4977]: Corrupted slices with H264 output in Low Latency mode
• Bugfix: [LT-5001]: Deadlock in frame rate conversion, optimized threading

UX/UI Improvements

• UI: Prefill input IP as the first IP of the selected NICs
• UI: Reorder input boxes, add ANY interface implying 0.0.0.0
• UI: remove 'Compliance with' from input (still possible through JSON)
• UI: hostname added into System info page

Security

• SNMP OS services are disabled by default for security reasons. User needs to enable them manually to use SNMP.

New Features

• Output TS bitrate is precisely estimated, leading to fine-tuned restriction for total bitrate overhead (based on resulting TS content)
• A user can fine-tune Frameformer library specifically for 4K video from settings.ini
• New TS Muxer (experimental) allows VBR mode
• SRT library updated to v1.5.3

Bugfixes:

• Bugfix: New TS Muxer (experimental): multiple bugfixes
• Bugfix: [LT-4977]: Corrupted slices with H264 output in Low Latency mode
• Bugfix: [LT-5001]: Deadlock in frame rate conversion, optimized threading
