How can i compile ffmpeg with x264?

[chengzhf]

hi, thanks for your script, it's great helpful. Now i want to compile ffmpeg with x264 for iOS, what command should I write to use this script? Actually I want to use the 'preset' argument of ffmpeg but there is a hint "no such argument". I google that it needs the x264. So I want to compile the ffmpeg with x264. Thank you very much.

1. Build x264 for iOS
2. Uncomment the line containing "X264=" and point it to your x264 build output
3. Modify any other configure flags if needed
4. Run script

Thank you for your answer. I try to use your another script: x264-iOS. I download x264 source and rename to x264 in the directory where the file build-x264.sh is, and run ./build-x264.sh. The x264 source version is x264-snapshot-20141218-2245. After the running, there are three more folders in the directory:scratch-264, thin-x264 and x264-iOS. In x264-iOS folder, the lib folder has only a *.a. I use the command "lipo -info *.a" to see what architectures it has, and it show that "Architectures in the fat file: *.a are: i386 x86_64". No arm architectures. Did I make anything wrong?

And there are a lot of warnings:
warning: unknown warning option '-Wno-maybe-uninitialized'; did you mean
'-Wno-uninitialized'? [-Wunknown-warning-option]

I get the following using http://download.videolan.org/x264/snapshots/x264-snapshot-20141218-2245.tar.bz2.

$ lipo -info x264-iOS/lib/libx264.a 
Architectures in the fat file: x264-iOS/lib/libx264.a are: armv7 armv7s i386 x86_64 arm64 

By the way, you should open a separate issue in x264-iOS repo when you have some problem with it.

I've built everything correctly however I'm getting final linking errors in my app.

"_pp_free_context", referenced from:
"_pp_free_mode", referenced from:
"_pp_get_mode_by_name_and_quality", referenced from:

If you have any feedback on what other libraries I'm missing. Google turns up nothing.

[fzakaria]

I was missing a new static library that got re-generated.
I had added all the previous static libraries prior to running it with x264 build!

D'oh!

Hi kewl,

I tried your scripts. What I am looking for is to create a libffmpeg.a in lieu of an executable binary i.e. ffmpeg

Any help would be much appreciated
