UltraGrid 1.8.4

Built 2023-08-22T13:30+00:00

Changes:

• added Reed-Solomon for audio
• added support for RPI4 hw. acceleration
• added holepunching support for where both hosts are behind NAT
• added experimental echo canceller support
• added unix_sock display for passing video frames to other processes via unix sockets
• added audio filter 'delay' for delaying audio on sender
• added audio filter 'playback' for monitoring audio on sender
• testcard (audio) - file playback now respects bps from --audio-capture-format
• converting sound samples to a lower bit depth now uses dithering
• transcoding reflector - ports with same the compression now reuse compressed frames instead of doing the same work
• conference mode now automatically sends back video to all participants
• improve H.265 recovery from packet drops (enabled constrained-intra)
• improve svt-av1 compatibility
• GUI: preview now uses unix sockets instead of shared memory
• GUI: should now behave correctly when running multiple instances
• GUI: added RTCP receiver report based RTT and packet loss indicator
• GUI: added send bandwidth indicator
• GUI: separate vuMeters for send/receive
• GUI: don't show crash dialog if UltraGrid crashed when exiting
• added dynamical scaler for DeckLink audio to eliminate clock drift
• support for libsoxr resampler (16/32 bits), added 32-bit support to SpeexDSP + use multiple threads
• encryption - added + made default encryption in AES GCM mode (+ support for WolfSSL)
• added Vulkan display

Fixes since last release:

1.8.1

• CI build fixes
• fixed lavc QSV initialization fail
• fixed AVFoundation device order instability
• [Vulkan] fixed 16-bit RGB display
• fixed GUI crash
• double-framerate vo postprocess fixes
• Vulkan is now enabled in Linux builds; macOS builds link with MoltenVK, so that Vulkan works there as well

1.8.2

• build fixes
• fixed lavc subsampling option parsing
• fixed inaccurate rendering of some codecs with Vulcan (R10k, UYVY, Y416)
• fixed inability to run portaudio + decklink at the same time in Windows
• fixed PortAudio default devce selection and capture channel count

1.8.3

• build fixes
• fixed libavcodec compression of videos with very small resolution
• [GPUJPEG] fixed parsing of q=/restart= options
• Reed-Solomon - support for multiple tiles
• [dshow] fixed indexing of devices in help
• fixed reflector address overflow + conference participant removal
• fixed DeckLink incorrectly displaying interlaced video

1.8.4

• build fixes
• fixed frame drop during RTP wrap-around
• file video capture - detect interlacing
