Hello! I can successfully build ffmpeg using a cross compile toolchain (linaro). What I need on my target system is mostly ffplay, however, FFPLAY is missing. Some google searches showed that SDL is required to build FFPLAY, so i installed libsdl2-dev. I am running ./configure using ./configure --enable-cross-compile --cross-prefix=<toolchain_path>/arm-linux-gnueabihf- --arch=arm --cpu=armv7-a --target-os=linux what generates a warning: WARNING: <toolchain_path>/arm-linux-gnueabihf-pkg-config not found, library detection may fail. what is correct, there is no -pkg-config in the toolchain. config.mak had a line !CONFIG_FFPLAY=yes that i removed the ! from. On 'make', everything is build just fine except for ffplay: CC ffplay.o ffplay.c:56:17: fatal error: SDL.h: No such file or directory compilation terminated. I don know if the error is related to the warning I got on running the configure script. Do I need SDL to be built for the target platform (= cross compile and then link the result (how would i link this?)?) or should it be working right away? If -pgk-config does not exist, is that a problem? If what I want is not possible for some reason, what might be an alternative to ffplay?
