Highlights

• Introduction of decode launcher for GUI users
• MacOS Builds Fixed
• HiFi-Decode fixes and quality now at/surpassing hardware for VHS/8mm

Decode Launcher

• A simple cross platform GUI interaction launcher for binary build users.

TBC-Tools

This release includes a experimental ld-analyse & tools release with export and chroma-decoder adjustment carry though integrated, and SQL/JSON duel support for current upstream ld-decode support until decode-orc development has fully replaced the legacy ld/tbc-tools suite for vhs-decode.

ld-analyse improvements

happycube#922 by @vrunk11

• Native Y/C view support, clean Y channel with Y+C source mode on.

• Internal Y/C to CVBS combine feature addded.

• Mono decoder now also supports luma NR in ld-analyse and in the chroma-decoder
