This includes\ncomputing/validating checksums at various levels and dealing with subtle edge\ncases related to VANC line formatting such as ensuring packets are contiguous.\n \nThe library also provides utility functions for various colorspaces VANC\nmay be represented in, including the V210 format typically used by\nBlackMagic Decklink SDI cards.\n\nBeyond this Readme.MD file, API level documentation can be generated via\nDoxygen (see \"Making Documentation\" section below).\n\nUsers should refer to the \"tools\" subdirectory for some test code which\nwhich make use of the library.  For a \"real world\" application, refer to\nthe klvanc-tools package, which make use of libklvanc in conjunction with\nBlackmagic cards to capture real SDI signals.\n\nhttps://github.com/stoth68000/klvanc-tools\n\n# LICENSE\n\n\tLGPL-V2.1\n\tSee the included lgpl-2.1.txt for the complete license agreement.\n\n## Dependencies\n* Doxygen (if generation of API documentation is desired)\n\n## Compilation\n\n        ./autogen.sh --build\n        ./configure --enable-shared=no\n        make\n\n## Making Documentation:\nTo make doxygen documentation in the doxygen folder, run the following command:\n\n        make docs\n\nTo view the documentation, cd into the doxygen/html/ directory and open the index.html file in a browser window.\n## Verifying the compilation:\nThe library comes with a series of test cases which allow the user to confirm\nthe library is working appropriately (as well as allowing us to watch for\nregressions).\n\nTo run the tests after compilation, run the following command:\n\n        make test\n\n## Compilation with meson\n\nMeson can be used as an alternative to autotools:\n\n        meson build\n        ninja -C build\n\nThe documentation will be built automatically if Doxygen is available\n\n## Running tests with meson\n\n        meson test -C build\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstoth68000%2Flibklvanc","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fstoth68000%2Flibklvanc","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fstoth68000%2Flibklvanc/lists"}
