0

-D_THREAD_SAFE -I/Volumes/ffmpeg_compile/include/SDL2

-L/Volumes/ffmpeg_compile/lib -lSDL2

Above are the result of requested command.


May be I forget very essential thing on configuring ffmpeg.  That is to add “—enable-sdl2”.
./configure —help saids “—disable-sdl2” is auto detect.  So I thought “—enable-sdl2” is not required.

Now I get SDL2 support yes and enabled program contains ffplay…But ffmpeg get build error like:

LD	ffmpeg_g
LD	ffplay_g
LD	ffprobe_g
Undefined symbols for architecture x86_64:

      _SDL_iconv_REAL in libSDL2.a(SDL_iconv.o)
      _SDL_iconv_string_REAL in libSDL2.a(SDL_iconv.o)

I’m now working to solve this error...
