ffmpeg ios build

-




After a couple of days I have made step by step instructions for this install:
FFmpeg Build Instructions MAC 10.8 or better
Copy ffmpeg-2.0.tar.bz2 (https://ffmpeg.org/releases/ffmpeg-1.0.7.tar.bz2, https://ffmpeg.org/download.html) and Unzip to Documents folder
Make sure you have the latest Command Line Tools under Xcode >; Preferences >; Downloads >; Components
Install gas-preprocessor
  1. Click on the ZIP icon to download https://github.com/mansr/gas-preprocessor.
  2. Copy gas-preprocessor.pl to /usr/bin directory.
  3. Change permission of gas-preprocessor.pl by setting the privilege to Read & Write for all.
Bug in xcrun starting in version 10.8
open terminal and paste in following command and press enter:
export DEVELOPER_DIR="/Applications/Xcode.app/Contents/Developer/"
cd to ffmpeg-2 folder and paste in following command and press enter:
mkdir armv7
mkdir armv7s
mkdir i386
mkdir -p universal/lib
To config armv7 library paste in following command and press enter:
./configure --prefix=armv7 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7 -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic
(Note: if config fails go to Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/ and make sure that the sdk folder is iPhoneOS6.1.sdk, if not change the config command to reflect iPhoneOSx.x.sdk and change all targets to x.x)
To build and install armv7 library paste in following command and press enter:
make clean && make && make install
To config armv7s library paste in following command and press enter:
./configure --prefix=armv7s --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" --extra-cflags="-arch armv7s -mfpu=neon -miphoneos-version-min=6.1" --extra-ldflags="-arch armv7s -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk -miphoneos-version-min=6.1" --arch=arm --cpu=cortex-a9 --enable-pic
(Note same rule as above: if config fails go to Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/ and make sure that the sdk folder is iPhoneOS6.1.sdk, if not change the config command to reflect iPhoneOSx.x.sdk and change all targets to x.x)
To build and install armv7s library paste in following command and press enter:
make clean && make && make install
To config i386 (so simulator will work ) library paste in following command and press enter:
./configure --prefix=i386 --disable-ffmpeg --disable-ffplay --disable-ffprobe --disable-ffserver --enable-avresample --enable-cross-compile --sysroot="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk" --target-os=darwin --cc="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/usr/bin/gcc" --extra-cflags="-arch i386" --extra-ldflags="-arch i386 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator6.1.sdk" --arch=i386 --cpu=i386 --enable-pic --disable-asm
(Note: this is not the same command as the previous two config commands, if you just arrow up to them this will fail)
To build and install i386 library paste in following command and press enter:
make clean && make && make install
To make universal library ( which is the library added to xcode ) paste in following command and press enter:
cd armv7/lib
for file in *.a
do
cd ../..
xcrun -sdk iphoneos lipo -output universal/lib/$file  -create -arch armv7 armv7/lib/$file -arch armv7s armv7s/lib/$file -arch i386 i386/lib/$file
echo "Universal $file created."
cd -
done
cd ../..

Formatting the code will make this easier to read. You can highlight the text and hit ctrl+k or command+k (I think), or click the code button above the text box which looks like {}. –  LordNeckbeard Aug 1 '13 at 20:14
    
Can you add the support for iOS7? –  ppaulojr Oct 14 '13 at 16:05
    
I tried using the above instructions with ffmpeg2.2 from ffmpeg.org/releases and gas-preprocessor from here github.com/michaelni/gas-preprocessor but, i got only static libs files (can i create an executable from this?) also, i don't see the ffmpeg anywhere...? should I have removed the disable-ffmpeg from the configure? can you elaborate what it means each parameter? if i just want to convert from one audio file format to another? (or merge stereo to mono?) what settings should i use to configure the scripts above? i want the binary output to be as small as possible... –  Itay Levin Apr 16 at 6:09

둘 중 누군가 그녀를 죽였다, 범인 해설

사건을 현실적인 눈으로만 따진다면 왜 추리소설을 읽겠는가마는, 히가시노 게이고의 흥행성을 인정하는 나로서도 이 책에서 따로 봉인 설명까지 곁들인 것치고는 추리논리가 군색함을 피할 수 없다고 생각한다. 작가는 크게 두 가지 근거를 들어, 준이치가 범인이라는 결론을 만들어두고 독자들의 호기심을 끌었다. 그 두 가지 근거는 첫째, 약봉지 두 개가 모두 일정한 방향으로 오른손잡이가 뜯었다는 점 그리고 둘째, 반창고가 높은 곳에 있어 이를 꺼낼 만한 사람은 소노코 혹은 준이치의 키가 되어야 한다는 점을 들고 있다. (가요코는 키가 이들보다 작다고 기술되어있다.) 봉인 설명서에서도 이런저런 대화식으로 처리했지만 어쨌든 이 두 가지를 결정적 근거로 삼고 있다. 그런데 이 두 가지 사실을 범인 판단 기준으로 삼는다고 쳐도 소노코 자살설 또한 그대로 유력하게 된다. 왜냐하면 소노코가 사실상 양손잡이이기 때문이다. 소노코가 글을 쓰는 것과 같은 행동들은 오른손을, 또 몇몇 행동들은 왼손을 사용한다는 식으로 기술해서 아마 준이치가 소노코가 명확히 어떤 손잡이인지 몰랐거나 뚜렷하게 인식하지 못 했다는 것을 분명히 하기 위한 장치 (만일 준이치가 소노코가 어느 손잡이인지 알았다면 약봉지를 뜯을 때 주의할 수도 있었어! 라는 가능성을 차단하기 위한 장치)로 썼던 것 같은데, 어찌 되었든 결국 그런 식의 기술은 소노코를 양손잡이로 만들어버리고 말았다. 뭐, 특정 행동은 반드시 특정 손을 쓴다고 하는 식으로 우겨 볼 수 있겠지만, 어쨌든 소노코의 오빠나 가가 형사 또한 소노코가 약봉지를 뜯을 때 어느 손으로 뜯을지 확신하긴 어려운 상황이 설정된 셈이다. 다시 말해, 소노코는 사실상 양손잡이인데다가 만일 당시의 포즈나 행동에 의해 다른 손을 사용할 가능성도 있기 때문에 판단 근거중 하나가 대단히 모호한 상태로 남게 되어버린다. 또 한 가지 근거인 반창고를 꺼낼 수 있는 키높이에 대한 것은 소설에서도 어찌 보면 미미한 근거로 드러나고 있다. 발판 같은 것을 구해서 반창고

[MAC OS X] mds_stores 100% CPU usage

[MAC OS X] mds_stores 100% CPU usage Today the CPU usage and sound of the system fan drove me crazy. The evil was the mds_stores process. mds_stores is a part of Spotlight and it’s indexing engine. After a small amount of time i decided to turn that shit off. I do not use the Search of OS X so i do not need that thing. to turn the indexing off write that to your Terminal: sudo mdutil -a -i off maybe you want the indexing back: sudo mdutil -a -i on Here is the Man Page of mdutil: https://developer.ap … s/man1/mdutil.1.html

tips more on unity ...

in the case of os x, find in MacOS folder Easy answer:     1.    copy AndroidManifest.xml from C:\Program Files (x86)\Unity\Editor\Data\PlaybackEngines\androidplayer to [your game]/Assets/Plugins/Android     2.    edit that file to include everything needed by both of your plugins     3.    Build and enjoy! Crazy answer that I started typing first before I thought of Easy answer:     1.    grab the Amazon Android SDK, and install the unitypackage.     2.    look at the manifest.xml that it puts in Assets/Plugins/AmazonIAPAndroid , and create your own manifest.xml files following the same format, in their own folders in /Assets/Plugins . (so, you'd have one Assets/Plugins/Vuforia/manifest.xml and one Assets/Plugins/EasyCodeScanner/manifest.xml )     3.    In the Unity Editor, under the "Amazon" drop down menu, run "generate androidmanifest.xml"     4.    That should create an AndroidManifest.xml in Assets/Plugins/Android which combines the stuff you specified in
