FFmpeg: building example C codes

问题

I have configured and compiled the FFmpeg library using this link: https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu

Now, I am trying to build example C codes provided by FFmpeg from here: https://github.com/FFmpeg/FFmpeg/tree/master/doc/examples

However, when I run make install-examples or make install (suggested by /example/README), I receive this kind of message:

make: *** No rule to make target '/doc/examples/README', needed by 'install-examples'. Stop.

I thought this may be due to the rules not being in the correct MakeFile format (I am not sure why they refers to README). How should I go about in fixing this and compiling the example codes? I have tried to find solutions about this, but there doesn't seem to be much information online.

Thank you.

回答1:

Run ./configure && make -j4 examples in the FFmpeg source directory, then look in doc/examples for the compiled examples.

• Requires make and pkg-config.

• To remove the compiled examples use make examplesclean in the FFmpeg source directory.
