Have used brew to install imagemagick and ghostscript. However, when i try to use the php extension imagick i can't convert pdfs to jpgs.
When i do it in terminal with 'convert' there is no problem.
When i look at my delegates in imagemagick i can't seem to locate gs.
convert -list delegate produces this:

This tells me that "gs" is indeed in use for some kind of pdf converting, and may be the explanation to that it works in the terminal with convert.
Here is the part that i can't understand and that i need help with.
when i execute 'convert -list configure' i get the following result:

in the CONFIGURE line i can read --without-gslib even though i chose brew install --with-gslib. Also, gs doesn't show up as a delegate in convert -list configure even though it shows as an option in convert -list delegate.
I have tried uninstalling both ghostscript and imagemagick and installed ghostscript first and then imagemagick. Nothing changed. I can't seem to be able to install it with ghostscript.
Can anyone help me? I would appreciate that a lot!

I compiled FFMPEG libs which supports for iOS 7 and 8 but since recent release with iOS 9 there is a new feature has issued which called bitcode mode , as a default setting , this setting has set to NO .
But if i set this as yes , following error will execute ,
libavdevice.a(avfoundation.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64
Is there any way to compile FFMPEG which supports FFMpeg in bitcode enabled mode

I got it working using the following CONFIGURE_FLAGS:
CONFIGURE_FLAGS="--enable-cross-compile --disable-debug --disable-programs \
--disable-doc --enable-pic \
--extra-cflags=-fembed-bitcode --extra-cxxflags=-fembed-bitcode"
If you only need to decode videos, you should add more flags to disable all muxers,encoders. You'll also probably don't need filters. This will save some space. I also disabled the ARCH i386, which is not needed for the iOS simulator.
I use these flags for my project:
CONFIGURE_FLAGS="--enable-cross-compile --disable-debug --disable-programs \

Add -fembed-bitcode-marker to CONFIGURE_FLAGS
like this:

--disable-doc --enable-pic -fembed-bitcode-marker"
I compile ffmpeg in OSX. My xcode version is 5.1. ffmpeg configure is :
./configure --disable-doc --disable-ffmpeg --disable-ffplay --disable-ffserver --enable-cross-compile --arch=arm --target-os=darwin --cc=/Applications/Xcode.app/Contents/Developer/usr/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/usr/bin/gcc ' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS7.1.sdk' --enable-pic --disable-asm --prefix="../lib"
This is the error:

ar: internal ranlib command failed
make: *** [libavfilter/libavfilter.a] Error 1
I'm not sure what this error means or how to solve it.
I see you are trying to build it for ARM, therefore iOS...
It's not that simple... run this script here... if you uncomment X264 you can compile it with libx264, if you need that, I can send you the other script later.

Unluckily, the config.log shows:
check_pkg_config librtmp librtmp/rtmp.h RTMP_Socket
pkg-config --exists --print-errors librtmp
Package librtmp was not found in the pkg-config search path.
Perhaps you should add the directory containing `librtmp.pc'
to the PKG_CONFIG_PATH environment variable
No package 'librtmp' found
ERROR: librtmp not found
I have googled and knew that configure contains a line enabled librtmp && require_pkg_config librtmp librtmp/rtmp.h RTMP_Socket, which maybe be wrong. Right? Can somebody help me to solve it?
UPDATE at 2014/06/10
I think it's about pkgconfig or something, so I have create a file named librtmp.pc at /usr/local/lib/pkgconfig, which contains below text:
prefix=/usr/local/librtmp
exec_prefix=${prefix}
libdir=${prefix}/lib
includedir=${prefix}/include
Name: librtmp
Description: RTMP implementation
Version: v2.3
Requires:
URL: http://rtmpdump.mplayerhq.hu
Libs: -L${libdir} -lrtmp -lz
Cflags: -I${includedir}
Also I have moved built librtmp to /usr/local. After above being done, I run the shell script again, but still same error! Can somebody told me why and how to solve it?
The below links give some insight while building ffmpeg.
https://trac.ffmpeg.org/wiki/CompilationGuide/Generic
Check whether LD_LIBRARY_PATH environment variable is set properly.
I am encoding PCM data to AAC format using ffmpeg:
Following is my code to setup the context object:
-(id)encode:(short*)data{

AVCodec *codec;
avcodec_register_all();
//Set up audio encoder
codec = avcodec_find_encoder(AV_CODEC_ID_AAC);
if (codec == NULL){
NSLog(#"no codec");
}
audioCodec = avcodec_alloc_context3(codec);
audioCodec->strict_std_compliance = -2;
audioCodec->bit_rate = 64000;
audioCodec->sample_fmt = AV_SAMPLE_FMT_S16;
audioCodec->sample_rate = 8000;
audioCodec->channels = 2;
audioCodec->profile = FF_PROFILE_AAC_MAIN;
audioCodec->time_base = (AVRational){1, 8000};
audioCodec->codec_type = 1;
if (avcodec_open2(audioCodec, codec, NULL)) {
NSLog(#"could not open codec");
}
return #"NO";
}
I always get an error log as :
aac # 0x151cda00] Specified sample format s16 is invalid or not supported
If I don't provide any sample format, I get the same log:
aac # 0x151cda00] Specified sample format -1 is invalid or not supported
and that's why avcodec_open2() gives log of could not open codec ;
Can some 1 tell me what is the issue?

I was having a similar issue as I did not know what format my Windows Phone supported. (turns out it was AV_SAMPLE_FMT_FLTP )
I ended up looking at the avcodec_open2 source code (https://www.ffmpeg.org/doxygen/2.1/libavcodec_2utils_8c_source.html)
And discovered it was referencing the codec to see which samples were supported.
With that in mind you can do something like this:
audioCodec->sample_fmt = audioCodec->codec->sample_fmts[0];
Maybe the error is misleading.
Try removing the line:
audioCodec->profile = FF_PROFILE_AAC_MAIN or changing it to audioCodec->profile = FF_PROFILE_UNKNOWN
Try compiling in the fdk-aac encoder: https://github.com/mstorsjo/fdk-aac The output quality is much better and it supports a wide range of sample rates and bitrates. To my knowledge, the native ffmpeg encoder is not very good in comparison. But maybe you can't use fdk-aac because of the license (you will need to pay patent royalties to Fraunhofer):

I'm trying to compile the ffmpeg by using the make and build files in iFrameExtractor example. firstly i tried to follow the readme file on the github, which only says to run the ./build_universal in ffmpeg folder. it did not work
i then tried to follow the info in INSTALL without success. i then tried doing the stuff in INSTALL followed by the ./build_universal which didn't work. All the *.a files that are imported to the project exists until the end of the build sequence. when the lipo commands in build_universal are run, which i guess concat the .a files for the different architectures(?). anyhow these leave the following errors:
lipo: specifed architecture type (armv6) for file (armv6/libavcodec.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavdevice.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavformat.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libavutil.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
lipo: specifed architecture type (armv6) for file (armv6/libswscale.a) does not match it's cputype (16777223) and cpusubtype (3) (should be cputype (12) and cpusubtype (6))
i can get the project to compile for simulator if i only use ./build_armv7 but if i run the universal the .a files are removed in the end. and only using doesn't work to build for iphone 4 .
After a week of trial and error, I was finally able to create the ffmpeg universal libraries and successfully compile and run iFrameExtractor for the device as well as the simulator.
To compile and run the project on your iPhone device OR simulator:
1) open Terminal
2) clone the repository: git clone git://github.com/lajos/iFrameExtractor.git
3) go to the ffmpeg folder in the project: cd iFrameExtractor/ffmpeg
4) run: ./configure
5) Edit the build scripts (build_armv6, build_armv7, build_i386) as follows:
These scripts assume you are using iOS SDK 5.0 on Xcode 4.2.
build_armv6:

6) build the ffmpeg libraries: ./build_universal
7) open the xcode project and run it on your iPhone device or simulator
These steps work perfectly for me. I hope this will help others struggling to get the ffmpeg libraries working for iOS.
i downloaded the latest ffmpeg repository and used the following to compile only for armv6 and armv7. I couldn't get it working for i386, i receive errors that the cputype and subcputype are wrong. apparently the cputype is supposed to be x86 and subcputype should be intel.
anyhow i used the following build scripts to compile for the arm architectures:
build script:
#!/bin/sh
set -e
SCRIPT_DIR=$( (cd -P $(dirname $0) && pwd) )
DIST_DIR_BASE=${DIST_DIR_BASE:="$SCRIPT_DIR/dist"}
if [ -d ffmpeg ]

if [ -d $DIST_DIR/bin ]
then

then

and combine libs script:

lipo -create $LIPO_CREATE -output $OUTPUT
lipo -info $OUTPUT
done

cp -R dist-$MAIN_ARCH/include/* $OUTPUT_DIR/include
then i import the .a files from BUILD-FOLDER/dist-uarch and it builds in xcode like a charm!
