Changes:

• added reflector wrapper handling both audio+video • Cineform can be decoded through lavd (if native not compiled) • vo_pp,cf/text performance improved • AJA：use new libajantv2 open-source library instead of old ntv2 one • enable multithreading for some less common lavc encoders (eg. OpenH264) • vcap/decklink：improve profile handling, support for topological ID • cmpto_j2k：support for CPU implementation, added R12L CUDA conversion • vcap/dshow：support for OBS virtual camera • add audio filter channel_remap for remapping on sender • improve FEC resilliancy if traffic is low • vcap/rtsp：support for authentization, stability fixes • vcap/rtsp (recv), rxtx/rtsp (send)：support for HEVC and JPEG • SDL3 support • full Wayland support, including GUI, OGL, Vulkan [Linux] • GUI：support for server/client mode • support for DeckLink IP features • audio conference mode supports passive (listen-only) participants • compilation supported on BSD systems • support for Samsung's Advanced Professional Video (via FFmpeg) • updated DELTACAST codebase (support for new cards, formats)

Fixes since last release:

1.10.8

• Windows CI build fix • fix GUI default random control port • fix PipeWire crash when server not running

1.10.7

• decklink - fix 2 opts parsing - :profile=1dfd (parsed to a wrong val) and :Use1080PsF=false (actually inverted the flag) • OpenCV 5 compat • few small fixes (macOS sha2 CI tool changed, unimportant leak)

1.10.6

• use latest AJA SDK • fix audio network packets not being freed under some conditions • trafic shaper - use CLOCK_MONOTONIC - this prevents freeze in Win when resuming from S3 sleep • really add files required to run standalone configure without the need for autoconf/automake • [v4l2] fix use-after-free (hopefully just dev name not print) • [acap/portaudio] fix some cap devices not shown in help • [portaudio] improved exitting (fix a crash)

1.10.5

• fix seldom audio corruption • fix presentation of portaudio devices in help • add configure (user doesn't need autoconf/automake)

1.10.4

• fix default VP9 on x86-64 pre v3 (wo AVX2). But the libvpx-vp9 seem to be better encoder than libsvt_vp9 in any case. • fix crash on querying directshow devices (GH-493) • compilation fixes of various seldom used modules

1.10.3

• screen_avf：fix swapped name/dev in probe (for GUI) • compliance with Apple Dev Program (explicit recording notice if screen capture or Core Audio device is used) • reenable CFHD decoding fallback with lavd • fixed some small lavd regression when some decoders unavail

1.10.2

• fix Vulkan display crashing on keypresses in console • fix GL display show/hide cursor keybind • fix control port argument in hd-rum-translator (GH-482) • added 2 conversions for Videotoolbox 10b encode (GH-479, GH-480) • modified hevc_videotoolbox not to default to 4:2:0 (GH-480) • bundle libdecor so that the windows (GL/SDL/Vulkan) have decorations in Wayland • make SPOUT running again (GH-487) • fix VDPAU being advertised/used with GL even when undesirable • fix GPUJPEG subsampling detection (probe, by updated GJ upstream) • ported AV Foundation vcap from master so that it can be used as a screen capture for macOS Intel builds (the old Core Graphics cannot be built anymore) (GH-485)

1.10.1

• fix temporarily broken r12l_to_gbrp16le (GH-476) • missing arm64 macOS dependency on brotlicommon (GH-478) • add libOpenGL.0.so library fallback to Linux AppImage • fix Pipewire screen capture not starting • build fixes • reenable AV Foundation (not being enabled on macOS) • fix decoding ProRes (GH-481)
