error: reference to 'byte' is ambiguous

[jiangyiqi99]

When I was usingMSYS2 to build in Windows, it appears this issue.
Appears when it execute to "g++ -MMD -MP -DUNTR_VERSION="v366-68a7990-dirty" -isystem./ffmpeg-7.0.1 -std=c++17 -D_FILE_OFFSET_BITS=64 -g -o .build_7.0.1/src/codec.o -c src/codec.cpp"
But the same source code can be successfully made in macOS
