New Features:

• added support for SDI playback via DeckLink cards
• added a new GUI to configure DeckLink inputs or outputs
• added support for hardware accelerated video decoding for AV1 codec
• new decoding layer to use better multi-threading/buffering to avoid draining of audio playback buffer when a long sequence of input video frames occurs (esp. AV1)

Improvements:

• automatic detection of input video format for DeckLink capture cards
• handling of overflows/underflows in the playback pre-buffering and improved playback (re-)start
• flow-control for HLS/MPEG-DASH streams and file inputs
• checks for encoder settings to avoid output aborts due to configuration conflicts
• display of input stream indices
• positioning and display of "Add Flow" button
• display of color attributes for decoded and encoded streams, also show these attributes for video playback

Bug-fixes:

• fixed display of decoding statistics for input streams captured from video/audio devices or screens
• fixed load/save of NDI based inputs and outputs
• fixed sub stream indexing for outputs (fixes NDI streaming of multilanguage inputs)
• fixes for detecting the visible video frame rate of input streams
• several fixes for receiving of MPEG-DASH streams
• fixed possible crash in internal packet ring buffers
• fixed RTMP broadcast server support
• fixed several license checks to support correct switch back from an expired trial license to a valid one

New Features:

• added STUN support (including GUI) to identify the own public IPv4/v6 addresses

Improvements:

• display for MPEG-TS based inputs also the pid of each individual input and encoding stream
• handle and show the A/V input PTS drift per input sub stream instead of per input
• improved display of measurement curves

Bug-fixes:

• fixes SRT connection breaks if the inbound stream has a high bit rate which causes a growing of the internal ring buffer
• fixed detection of frame rate and video resolution of H.264 streams for some special cases
• fixed automatic removal of an encoder instance if the last related output was closed

New Features:

• added support for HLS based real-time streaming to YouTube (including HDR support)

Improvements:

• several GUI UX cleanups, merged HLS file output into general file recording option
• accounting of outgoing traffic in case of HLS outputs
• improved/extended real-time curves about frame buffering and encoding for each individual encoder instance
• MPEG-TS program names now always contain the program type within the GUI
• improved error reporting in case an encoder or muxer instance cause a critical error
• playback problems for mp4 files when using remote control
• reworked internal packet ring buffers to improve support for 4k streams
• improved efficiency of RTMP packetizing (e.g., when streaming to YouTube)
• improved throughput of HLS muxer instances and avoidance of frame drops
• improved H.264 support to detected correctly the SPS data in special cases

Bug-fixes:

• "load flows" now waits until all input video/audio streams are detected before it adds an output to restore all desired encoder streams
• correct video encoder profile selection for HEVC streams
• possible crash situation during application shutdown
• possible crash situation when closing a live video/audio capturing
• endless decoding in case of file input and the playback was not started yet
• possible crash situation when closing a muxer instance
• possible rare crashes in encoder instances
• empty playlist files in case of HLS based file recording (only Windows)
• possible crash situation when closing a file input by remote control

New Features:

• allow to switch each video player to fullscreen mode
• added system overview dialog which shows details about the used hardware and software setup

Improvements:

• display decoder statistics grouped by programs if possible
• display input settings grouped by programs if possible

Bug-fixes:

• correct remote playback of video/audio data
• use an SRT latency of 120 ms as default setting instead of the previous 0 ms (fixes early data dropping in case of url based input)
• make sure the playback stays consistent and starts reliably the video display

New Features:

• allow to watch and listen to multi-program mpeg-ts based inputs (tested with up to 40 TV/radio programs per input)

Improvements:

• display input streams grouped by programs if possible
• display mpeg-ts programs based on their type (TV vs. radio) instead of their number
• allow to observe/handle mpeg-ts programs by remote control
• improved ordering of demuxer and decoder streams according to their media type
• improved/fixed support for gpu accelerated h.264/hevc video decoding for non mpeg-ts inputs
• support dynamic program changes within the mpeg-ts demuxer
• statistics about average timing of SPS, PPS and VPS NAL units within h.264/hevc video streams
• improved accuracy of demuxer statistics for mpeg-ts based inputs
• detect NVidia 3000/4000 series graphics cards
• added log redirection for libsrt to be able to read all SRT related log outputs in the central vase.log

Bug-fixes:

• possible crash situation when using input streams
• possible crash situation when closing a video/audio playback
• possible crash situation when starting a sound output
• correct detection of teletext streams in the mpeg-ts demuxer
• possible crash situation when selecting a different mpeg-ts program for playback
