ffmpeg

SDL2生成ffplay出錯，選擇使用SDL1.2

./configure --prefix=/usr/local/arm/ffmpeg --cross-prefix=arm-none-linux-gnueabi- --target-os=linux --arch=arm --enable-shared --enable-nonfree --enable-gpl --enable-pthreads --extra-cflags=-I/usr/local/arm/lame/include --extra-ldflags=-L/usr/local/arm/lame/lib --enable-ffserver --enable-libmp3lame --extra-cflags=-I/usr/local/arm/xvid/include --extra-ldflags=-L/usr/local/arm/xvid/lib --enable-libxvid --enable-version3 --extra-cflags=-I/usr/local/arm/x264/include --extra-ldflags=-L/usr/local/arm/x264/lib --enable-libx264 --extra-cflags=-I/usr/local/arm/sdl/include/SDL --extra-ldflags=-L/usr/local/arm/sdl/lib --enable-ffplay --extra-libs=-lSDL

因爲configure後 SDL support no而且生成的config.mak文件中CONFIG_FFPLAY=yes,HAVE_SDL=yes等都是被註釋掉的，因此須要手動修改config.mak文件，將CONFIG_FFPLAY=yes HAVE_SDL=yes的註釋去掉
