libLTC for Windows
This repository provides a Visual C++ solution to build libltc as libltc.dll for Windows.
To build your own DLL, open ./msvc/libltc.sln by Visual Studio and build the solution.
Your DLL will be generated as ./msvc/x64/{Release,Debug}/libltc.dll.
You can also find example_encode.exe, ltcdecode.exe, and ltcencode.exe in the same directory.
Once the DLL is compiled, you can import ./src/ltc.h and libltc.{dll,lib} into your own project.
Notice that the exported functions are not declared with __declspec(dllimport) nor __stdcall though these are popular in other DLLs. This design is based on the following pros and cons.
- Pros:
- We do not need to modify the original source files in
./src/.
- We do not need to modify the original source files in
- Cons (not really):
- We need to edit
./msvc/libltc.defto specify the functions to be exported. - We may want to use "whole program optimization". This option is enabled by default for
Releasebuilds. __cdeclis used instead of__stdcall.
- We need to edit
libLTC
Linear (or Longitudinal) Timecode (LTC) is an encoding of SMPTE timecode data as a Manchester-Biphase encoded audio signal. The audio signal is commonly recorded on a VTR track or other storage media.
libltc provides functionality to encode and decode LTC audio from/to SMPTE or EBU timecode, including SMPTE date support.
libltc is the successor of libltcsmpte. For more information, please see the FAQ in the documentation.
