# use vcpkg to build the ffmpeg.
|
|
|
|
|
- folow the instructions https://trac.ffmpeg.org/wiki/CompilationGuide/vcpkg

|
|
|
- run command
|
|
|
|
|
```
|
|
|
|
|
vcpkg.exe install ffmpeg[core,avcodec,avdevice,avfilter,avformat,speex,avresample,mp3lame,opus,sdl2,swresample,vorbis]:x64-windows-rel
|
|
|
|
|
```

|
|
|
- copy dll and libs in vcpkg\installed\x64-windows-rel to goldendict's winlibs\lib\msvc
|
|
|
|
|
|
|
|
|
|
**pros**: can be compiled with speex.
|
|
|
|
|
|
|
|
|
|
# alternative Method :
|
|
|
|
|
just download the ffmpeg from official website: https://github.com/BtbN/FFmpeg-Builds/releases
|
|
|
|
|
can replace the dlls and libs in the winlibs\lib\msvc
|
|
|
|
|
|
|
|
|
|
**cons**: seems lacks libspeex or I just download the wrong package.
|
|
|
|
|
|
|
|
|
|
**pros**: easy to manage.
