Compile using ffmpeg libraries
Tonight I wanted to play around with the ffmpeg API and see how complicated it was.  I downloaded the example decoding_encoding.c file and tried to compile it against a local build of ffmpeg I made based on their Ubuntu compiling tutorial.
Well let me tell you, ffmpeg sucks at getting people up to speed. Â Yeah it’s great they have a few examples on how to use the API, but their makefile is dependent on pkg-config, so it is totally useless for a cross compilation, you would have to add the libs path to your build machine, which is dumb. Â Not to mention the libraries they use in the example makefile are missing library references required for the example, leading to a TON of missing symbol errors! Â Well after a bunch of searching I found one or two references to people who got the examples built which lead to the commands to build the damn thing on my machine. Â This post is for everyone wanting to get started with the ffmpeg API and so I don’t loose it! Â Enjoy 🙂
The -I and -L paths should be to your ffmpeg build, mine was obviously /home/s1axter/projects/ffmpeg_sources/ffmpeg_build/
gcc -Wall -I/home/s1axter/projects/ffmpeg_sources/ffmpeg_build/include -c -o decoding_encoding.o decoding_encoding.c
gcc -Wall -L/home/s1axter/projects/ffmpeg_sources/ffmpeg_build/lib -L/usr/lib/i386-linux-gnu -o decoding_encoding decoding_encoding.o -lavformat -lavcodec -lswscale -lavdevice -lavfilter -lfdk-aac -lpostproc -lswresample -lx264 -lavutil -lvpx -lvorbisenc -lvorbis -lmp3lame -ltheora -ltheoraenc -ltheoradec -lva -ldl -lz -pthread -lm
And a Makefile:Â ffmpeg makefile
