• (PHP5) shell_exec("wine ffmpeg.exe") in ubuntu version 14

  29 juillet 2017, par user235423423424

  How to start wine in php shell_exec("wine ffmpeg.exe") ; ?

  (ubuntu version 14 server)
  

  install

  sudo apt-get install wine -y

  php5 code :

  $cmd = "wine ffmpeg.exe upload/image.jpg"
  
  shell_exec($cmd);

  ffmpeg.exe location :
  /var/www/html/

  wine is not starting ?

  Linux version of FFmpeg ?, how to run PHP shell_exec() ?

  Server domain is not on shared hosting

  permissions on www-data could be problem ?

  command ffmpeg successfull in terminal !
  

  there is a permission issue, just tested and command is correct.
  either ffmpeg.exe or wine have incorrect permissions.

  Command (ffmpeg.exe)

  chmod 755 ffmpeg.exe
  
  chown www-data ffmpeg.exe

  Command (/usr/bin/wine)

  chmod 755 wine
  
  chown www-data wine

  sudo service apache2 restart

  still not working, could be more ’wine’ files to apply permissions to.
  I’m not able to output any error, and command to ffmpeg is correct from terminal the problem must be permissions

• Building Ffmpeg library for iOS6.0 ARMv7 Processor success but compile error

  5 avril 2013, par user1800270

  I'm trying to use the FFMPEG library in an XCode 4.5.1 project.
  And I'm trying to build it for ARMv7.

  I had already build library by use the method below (provide by Alex) :

  ---

  Here is my working Configure for cross-compiling FFmpeg on iOS 6 the arch is ARMv7

  NOTE : You must have to have gas-preprocessor.pl inside /usr/local/bin/ please do not continue until you have gas-preprocessor.pl on your bin directory

  Download FFmpeg 1.0 "Angel" from here

  Unzip it and place it somewhere i.e. your Desktop folder

  Open terminal and browse to unzipped FFmpeg folder

  Copy and paste the following command, (be patient will take a while)

  ./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/bin/gcc --as='gas-preprocessor/gas-preprocessor.pl /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc' --sysroot=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk --cpu=cortex-a8 --extra-cflags='-arch armv7' --extra-ldflags='-arch armv7 -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.0.sdk' --enable-pic --enable-decoder=rawvideo --disable-asm

  Now type the following command on terminal make (wait a little more)

  Once it has finished now type on terminal sudo make install (wait again)

  Go to /usr/local/lib to find your freshly baked armv7 libs

  Enjoy !
