ffmpeg / libav libraries

[McZonk]

What library in which version do I need to compile the source?

[Yukon]

I too would like to know too as I have been having issues compiling. When running brew install ffmepg and building I get a lot of undefined symbols like "_faacEncClose". When uninstalling ffmepg and installing libav instead I am missing libavformat/avformat.h. So I am a little lost about how to compile.

I tried running with the latest FFMPEG and get like 20 "apple mach-o linker error"s. Help?

[McZonk]

I got it running. I have installed ffmpeg myself and faac, xvidcore and iconv via brew. It should be to install ffmpeg via brew too.
I have added a setup that works for me: https://github.com/McZonk/CocoaSplit/tree/mybuildconfig
@YukonAppleGeek The _faacEncClose are obviously the missing faac library.

[Yukon]

@McZonk There is nothing different with the branch. Could you write a simple guide or even step by step on getting the dependancies? It may seem stupid but I still have not gotten a working build of ffmpeg after trying so many different things. It may just an issue on my side but I do not know.

[McZonk]

@YukonAppleGeek It is a little bit tricky to write down a manual, because the setup depends on your installed libraries. Check your Xcode if any libraries are not found (red) and just install and add them. Also please note I'm not maintaining this project, I just did a few improvements.

Is zakk4223 even still around and could help us?

[Yukon]

I have figured it out finally. To fix compiling you need to edit the other linker flags on both CocoaSplit and CocoaSplitCmd targets and add /usr/local/lib/libfaac.a /usr/local/lib/libxvidcore.a /usr/lib/libiconv.dylib. To get the libraries if you do not already have them run brew install ffmpeg and that will install ffmpeg and its dependences. After you have made those changes it should compile.

[McZonk]

@YukonAppleGeek It is a typical problem. Your fix works for you, but it wouldn't work for me since you are referencing external libraries …

[Yukon]

It should work if you use brew to install the dependences which is the most simple and easy way to do it.

[zakk4223]

The actual problem here is I use a fairly minimal ffmpeg build, so I don't even build libfaac or libxvidcore. So it's mostly just an ffmpeg option thing. I believe all I use is --enable-gpl --enable-libx264 --enable-static

[DrabWeb]

Sorry if this is a bad question, but how do I set the settings for FFMPEG that zakk has?

[Yukon]

@DrabWeb Here is a guide https://trac.ffmpeg.org/wiki/MacOSXCompilationGuide.I am also having issues now with #10 when using my compiled version.

i solved those issues by uninstalling ffmpeg, faac, upgrading brew and then reinstalling both ffmpeg and faac:
brew rm ffmpeg && brew rm faac && brew update
brew install faac
brew install ffmpeg --without-lame --without-faac --without-xvid --without-opus

in order to fix this error message:
Undefined symbols for architecture x86_64:
"_swr_alloc", referenced from:
_opus_decode_init in libavcodec.a(opusdec.o)

i've added "/usr/local/lib/libswresample.a" to other linking flags.
so now it compiles for me
