New features

• transport_stream_id configuration in Service Description Dialog
• program_number configuration in Service Description Dialog
• LT-5883: Setting NORMALIZE_RTMP_TIMESTAMPS=0 allows for continuous RTMP timestamps even when it starts and stops again

Improvements

• BugFix: Crash when processing interlaced JXS or 2110 input streams higher than 1080px
• BugFix: Occasional missing frames in H26x interlaced output from NDI input
• BugFix: LT-5933: HLS output does not always create the master .m3u8 playlist with RTMP input
• BugFix: LT-5932: HLS output often stops updating rendition playlists on auto-reconfiguration

New features

• Video-less MPEG-TS output

Improvements

• BugFix: LT-5451: REST API /api/pipeline/{id}/state: duplicated 'elementaryStream' in each elementaryStreams[]
• BugFix: LT-5838: Wrong PES packet length for VBI data in TS
• BugFix: LT-5512: SRT listener: State not updated when waiting for connection
• BugFix: LT-5947: Deinterlacer: Wrong field order won't result in frame drop

New Features

• Auto-reconfiguration split into Auto-reconfiguration (Video configuration), Configuration mode (Audio configuration)
• Manual - Fixed channels mode for NDI allows for creation of 16 audio channels (first taken from input, others silent)
• Audio delay for inputs in Configure audio corrections dialog
• New implementation of NDI input element

Improvements

• BugFix: LT-5838: Invalid DVB teletext output stream due to added PTS
• BugFix: LT-5860: Wrong output audio stream order in UI
• BugFix: LT-5665: Volume gain unit (%) not visible
• Having low FPS on NDI input is not considered an error, actual FPS is reported in UI
• Detect and log jitter on PTS/DTS in incoming elementary streams
• Detect, log, and correct PTS jitter in AudioConvertElement for all kinds of inputs (previously only AES3)
• Detect, log, and correct PTS jitter on video frames in NdiSinkElement
• License Key is shown in Licensing page

New Features:

• Added logging for continuity counter errors and delays of packets for specific PID from TsDemuxer.
• Introduced NDI interlaced output (30p to 60i conversion).
• Added pass-through support for AIT metadata.
• Rate-control modes for TsMuxer (CBR, VBR, CVBR).
• Enabled running Live Transcoder on systems without NVIDIA NvEnc GPUs.
• Enabled I-frame only encoding for H.264, HEVC, and H.262 (GOP sizes between <1,300>)

Improvements:

• Addressed a crash in SRT network sender that caused connection issues.
• Corrected default NDI clocking mode to framesync.
• Resolved issues with hiding options in Webkit browser sink type selection.
• Workaround implemented for a broken field deinterlacer when the BOTTOM field is first.
