• How to compile FFmpeg for Android with clang in ubuntu18.04 ?

  31 juillet 2019, par user10959099

  I want to compile FFmpeg with clang as it’s more faster,but I don’t know how to do it in ubuntu.
  NDk version r16b ,ffmpeg version 4.1.

  I did it with gcc. here is my build script,and it works well.

  #!/bin/sh

  }
  
  build

  I wonder how to do it with clang friendly.I’m still new int the NDK and I’ve just started learning.So I have no idea to do it at all.
  When I was trying turn to clang,and get many errors.
  After trying so many times,I update my build script with this question :

• Does the installation of ffmpeg for Laravel use exe files ?

  I wanted to use the ffmpeg package of Laravel, but because it is a shared host, I cannot use the executable file
Is the Laravel ffmpeg package related to the A exe file ?

  


• Compile FFMPEG for command line usage

  3 septembre 2014, par Lior Iluz

  I’ve been trying to compile FFMPEG so I can use it with my Android application with commands. The result should be 1 static file, "ffmpeg", that is not package dependent. No .so files.

  I managed to compile it with guardianProject and everything is working but the source was too old and lacks options I need.
  I’m using the latest Ubuntu on VirtualBox, all essentials are installed and updated (gawk, yasm, aptitude, etc...).

  There are multiple examples around the web. Here are the issues I’ve experienced with each of the options I tried. I’d appreciate help with either one of the following errors :

  1. Guardian project - I managed to compile it and get the ffmpeg file but it uses an old version of ffmpeg that doesn’t include the "-movFlags faststart" option. I tried throwing the new ffmpeg (2.3.3) in there but it just throws error. (I ran git submodule init and update)

  2. JayH5 - A more generic build file that basically should work with every ffmpeg. I updated the build script to work with the latest NDK and it seems to be working but than it fails on /home/dor/Desktop/ndk/android-ndk-r10/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86/bin/arm-linux-androideabi-pkg-config not found, library detection may fail.
     I read about this and it seems to require a hack, which I don’t understand how to implement.

  3. Trovao - this is a very nice project and the build script even downloads the latest ffmpeg and x264 sources, and I even succeeded in compiling it to FFMPEG and X264 files but when I use it, I get this error : could not load library "libx264.so.142 which is weird, as x264 is there and the whole idea of this project is to cancel the need of .so files.

  I’d appreciate help with figuring out how to solve any of the issues. I prefer using the JayH5 build script as it seems the most straight forward out there...
