Version: v2.12.0

Bitstreams Release Notes

Release v2.13.0 - June 8th, 2026​

Requirements​

  • Quadra Firmware v5.5.1
  • Blackmagic SDK Version 16.0
  • Platform: AMD/x86 (ARM support is available, but testing was limited)

New Features and Improvements​

  • Add SMPTE 2110 support for Blackmagic capture card input mode using SDP file based setup
  • Source timestamp rewind/fastforward tolerance and alert system
  • srt_pull url query config options and defaults for latency and timeout
  • Add per-stream Runtime Settings to override valid config.toml runtime parameters for live streaming, configurable via GUI (Form and Raw views), REST API, and CSV import; settings are now also applied to manual source probe and failover probe
  • Add template option to support dynamic overlay image changes on live streams
  • Support H.264/H.265 Profile and Level settings in template, including global defaults and per-output overrides
  • (x64 only) Add support for LCEVC headers with null encoding for HLS output mode using H264 codec, enable in templates
  • Audio rescue for UDP multicast failover: when the active source's usable audio PID count drops below the per-stream Min Required Audio PIDs threshold, switch to the alternate side that meets the threshold; auto-fallback after the configured Failover Recovery Interval once the original side recovers
  • Add local file loop input type for live streams, seamlessly looping a local media file under /mnt as an offline source
  • Improve security for GUI via package updates

Resolved Issues​

  • Fix HLS ingest playlist DTS discontinuity + rewind demux stalling
  • Fix inconsistent "Mixing RAW SDI outputs and encoded outputs is not supported." error on Create Template Video page
  • Reject audio copy of incompatible source codecs into non-mpegts containers at probe time instead of failing at start of muxing

Known Issues​

  • HLS SCTE-35 Passthrough may lose traction after running for some time
  • Changing the template for HLS/DASH playback that has recording enabled while the stream is running can cause recording to fail
  • Local loop HLS input: live and rolling-window sources (without #EXT-X-ENDLIST) play through once but may not loop

Release v2.12.0 - April 24th, 2026​

Requirements​

  • Quadra Firmware v5.5.1
  • Blackmagic SDK Version 15.0
  • Platform: AMD/x86 (ARM support is available, but testing was limited)

New Features and Improvements​

  • Add new template:format option for 8-bit pixel format forcing on CPU decode streams
  • Add disk_usage_threshold_mb to stream-trans config to set disk usage threshold for file outputs, HLS recording and offline sessions.
  • Add rtmp_pull input support
  • Support configurable relative_probe_size to allow scaling probesize to the analyze_duration parameter
  • Add srt_listener output support

  • Drop with notification unrecognisable audio/video tracks. If no audio tracks give notification, for WHIP reject
  • Alert notifications for large and atypical jumps in source timestamps

Resolved Issues​

  • "Outdated template" warning is now consistent with playback restarts. Restarting an individual playback reloads the template from the most up-to-date version and clears the warning if it was raised previously
  • Fix Input Stream Details incorrect video details for certain HLS/DASH ladder inputs
  • mpegts input timestamp wraparound consideration for restarted streams in cmaf output mode

  • RTMP inputs: Detect and notify or reject sources with unrecognisable codecs at probe time rather than starting a stream that produces silent or dead output
  • Offline session names, source URLs, and output paths now handle '/', '%', and '' correctly. Live playback Output Name accepts '/' (creates a recording directory hierarchy) and rejects ''.

Known Issues​

  • Changing the template for HLS/DASH playback that has recording enabled while the stream is running can cause recording to fail
