error: avutil is required, but compiler can not find it.

You should set some environment vars so that compiler can find FFmpeg and other libraries files.

For VC compiler, they are INCLUDE and LIB. For gcc, they are CPATH and LIBRARY_PATH. e.g.

vc:

复制代码

1
2
3
set INCLUDE=ffmpeg_pathinclude;portaudio_pathinclude;%INCLUDE%
set LIB=ffmpeg_pathlib;portaudio_pathlib;%LIB%

gcc in unix shell environment(including mingw with sh.exe):

复制代码

1
2
3
export CPATH=ffmpeg_path/include:portaudio_path/include:$CPATH
export LIBRARY_PATH=ffmpeg_path/include:portaudio_path/lib:$LIBRARY_PATH

gcc in windows cmd environment without sh.exe

复制代码

1
2
3
set CPATH=ffmpeg_pathinclude;portaudio_pathinclude;%CPATH%
set LIBRARY_PATH=ffmpeg_pathlib;portaudio_pathlib;%LIBRARY_PATH%

If you are building in QtCreator, goto QtCreator's 'Projects' page and add or append those environment.

I think i should write some documents to show how to build QtAV.

不能自己添加名字！
