UltraGrid 1.7.5

Built 2022-06-21T10:36+00:00

Changes:

• DeckLink - capture supports signal bit-depth detection (8-bit capture is no longer default if not explicitly requested), support for HDR metadata in display
• Raspberry Pi - support for HW encoding of H.264
• higher bit depth support for various compressions - Cineform, libavcodec (libx264, VP9, NVENC)
• libavcodec - new compressions support and inclusion in Linux builds - SVT, rav1e, david; videotoolbox HW accelerated decoding
• NDI - support for 16-bit video, compatibility with NDI 5
• added some NAT traversal techniques - PCP, NAT-PMP and the server mode
• GPUJPEG - improved handling of color spaces - BT.609 and RGB is finally encoded natively allowing faster encode/decode and possibly also better fidelity by avoiding color conversions
• Support for 360 degree video stitching and playback
• GUI - now it's possible to select a specific encoder for each codec

Fixes since last release:

1.7.1

• fixed testcard pattern gradient2
• build fixes (OpenGL, SDP/HTTP, SVT VP9)
• broken JPEG from libavcodec if threads disabled (threads=no)
• AppImage: bundle i965-va-driver-shaders instead of i965-va-driver
• fixed AppImage GUI crash on Ubuntu 21.10 + compat with Rocky Linux 8.5

1.7.2

• fixed potential problem with multichannel audio when there is a BPS change
• build GitHub builds with NDI 5 by default (user still needs to obtain NDI library by itself)

1.7.3

• fixed channel mapping from lesser amount of input channels to higher (eg. --audio-channel-map 0:1 while receiving only mono)
• do not set BMD conversion mode (issue #215)

1.7.4

• fixed setting of intra-refresh build for NVENC with libavcodec (do not set, otherwise libavcodec sets infinite GOP meaning stream not being decodable from the middle /not at all to be more specific/)
• backported fixed RTSP capture from master
• build fixes

1.7.5

• build Linux version with SVT VP9/HEVC again
• minor fixes
