  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Building FFMPEG library for iOS5.1 ARMv7 Processor

    26 octobre 2012, par Jimmy

    I cleaned up my question a little bit, when I wrote it the first time I was flustered. Now I can be more clear after taking a small break.

    I'm trying to use the FFMPEG library in an XCode 4.5.1 project. And I'm trying to build it for ARMv7. What I'm looking for is the exact process, and some explanation. I understand that this is not a well documented problem. But I know that other pople have had the same problem as me.

    What I have been able to do.

    I have been able to build the library for xCode. here Is what I have been able to do step by step.

    1) I have been able to clone ffmpeg. For beginners this will get you started by creating a directory with the ffmpeg source. (Kudos to the guys who wrote it)

    git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg

    2) I have been able to write a config file that doesn't have any errors. We will go back to this part later. This is the command I attach to ./configure

    ./configure
    —disable-doc
    —disable-ffmpeg
    —disable-ffplay
    —disable-ffserver
    —enable-cross-compile
    —arch=arm
    —target-os=darwin
    —cc=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2

    —as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2'

    —sysroot=/applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk

    —cpu=cortex-a8
    —extra-ldflags='-arch=armv7 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk'
    —enable-pic —disable-bzlib —disable-gpl —disable-shared —enable-static —disable-mmx —disable-debug —disable-neon —extra-cflags='-pipe -Os -gdwarf-2 -isysroot /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
    -m$thumb_opt :-no-thumb -mthumb-interwork'

    These are some things to note.

    • I had to download ( https://github.com/yuvi/gas-preprocessor ) copy the file gas-preprocessor.pl at /usr/local/bin. Set permissions to read write (777)
    • Make sure I'm using the right GCC compiler : /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/llvm-gcc-4.2/bin/arm-apple-darwin10-llvm-gcc-4.2
    • Make sure I'm using the right SDK : /applications/xcode.app/contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.1.sdk
    • —extra-cflags="-arch armv7" causes : error : unrecognized command line option “-arch”

    Here in lies the problem.

    When I include the library and the declaration. Everything works fine ! (You will want to make sure your library paths in xcode are properly written if it can't find the library. There are plenty of people with this problem, stackover flow has a wealth of knowledge here)

    But when I started to write the encoder. I received this warning, and countless errors.

    ignoring file /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a, file was built for archive which is not the architecture being linked (armv7s) : /Users/Jimmy/Development/source.ffmpeg/Library/libavutil.a

    That means that I didn't build for ARMv7 and that -arch configuration I took out is actually essential.

    What I'm looking for is someone whose done it before, to walk all of us through the process of building FFMPEG for iOS5.1 and ARMv7 and the majority of things to look out for. If no one comes forth, in time I'll answer my own question and hopefully help out others who are struggling too.

  • link error Xcode libx264.a ARM

    19 novembre 2013, par user1558688

    I'm trying to build libx264.a to run on my iphone 4s ( running iOS 6.1.3 )

    I'm building it using the MACOSX 10.9 Terminal application :

    CC=/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang ./configure 
    
--host=arm-apple-darwin 
    
--sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk 
    
--prefix=armv7 
    
--extra-cflags='-no-integrated-as -arch armv7' 
    
--extra-ldflags="-L/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.0.sdk/usr/lib/system -arch armv7" 
    
--enable-pic --enable-static

    Which guives me the output :

    platform:      ARM
    
system:        MACOSX
    
cli:           yes
    
libx264:       internal
    
shared:        no
    
static:        yes
    
asm:           yes
    
interlaced:    yes
    
avs:           avxsynth
    
lavf:          no
    
ffms:          no
    
mp4:           no
    
gpl:           yes
    
thread:        posix
    
opencl:        yes
    
filters:       crop select_every 
    
debug:         no
    
gprof:         no
    
strip:         no
    
PIC:           yes
    
bit depth:     8
    
chroma format: all

    Then I run 'make' and it generates a libx264.a archive.

    So far, so good.

    On my Xcode (Version 5.0.2 (5A3005)) application I set :

    1) Build Settings -> Header Search Path -> x264 parent directory (../x264 )
    2) Build Phases -> Link Library with Binaries -> Add Other... ( ../x264/libx264.a )
    3) Build Settings -> Other Linker Flags : -ObjC

    In my AppDelegate.mm :

    #import "AppDelegate.h"
    
#import "x264.h"
    

    
@implementation AppDelegate
    

    
- (BOOL)application:(UIApplication *)application 
    
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    
{    
    
    x264_param_t x264param;
    
    x264_param_default(&x264param);
    

    
    // Override point for customization after application launch.
    
    return YES;
    
}
    

    
...

    When i try to run it on the device I get the error :

    Undefined symbols for architecture armv7:
    
  "x264_param_default(x264_param_t*)", referenced from:
    
  -[AppDelegate application:didFinishLaunchingWithOptions:] in AppDelegate.o
    
ld: symbol(s) not found for architecture armv7
    
clang: error: linker command failed with exit code 1 
    
(use -v to see invocation)

    Any idea how to fix this ?

    Thanks
