• Having problems compiling ffmpeg for Android

  25 mars 2013, par Budius

  I'm trying to compile ffmpeg for Android using this guy script (https://github.com/guardianproject/android-ffmpeg) because it looked like the simplest and the whole NDK is really not my area of expertise.

  So let's see what I've done so far :

  • Downloaded and installed a fresh Ubuntu 12.04 LTS from : http://www.ubuntu.com/download/desktop in a VirtualBox. (had some little problems with video but a few updates later in the terminal ubuntu is up and running)
  • installed the Android SDk and downloded/unzipped the NDK into /Documents/ndk
  • I used those commands to install the compiler :

  $ sudo apt-get update

  $ sudo apt-get upgrade

  $ sudo apt-get install build-essential

  $ gcc -v

  $ make -v

  • then sudo install git (or something like that to install git)
  • then git clone https://github.com/guardianproject/android-ffmpeg.git
  • then copied from the guys page building section
  • cd android-ffmpeg
  • git submodule init
  • git submodule update
  • NDK_BASE=/path/to/android-ndk ./configure_make_everything.sh

  it mostly goes well until it says :

  arm-linux-androideabi-gcc is unable to create an executable file C
  compiler test failed

  If you think configure made a mistake,.. blaah blahh blaah

  I'm not sure what it means or where to go from here.
  from this I did some chmod 777 on the folders to make sure stuff can be execute.

  also from this I tried his script but without any luck.

  help ?

  Skip comp inter mode tests for arf coding

  This commit skips the compound inter mode prediction check in the
  rate-distortion optimization loop for ARF coding. It reduces the
  runtime for certain test clips at speed 3, at no compression
  performance change :

  bus CIF 1000 kbps, 8260 ms -> 8090 ms, 1.8% speed-up
  stockholm 720p 1000 kbps, 74453 ms -> 71826 ms, 2.9% speed-up

  No visible speed-up for pedestrian area 1080p at 2000 kbps.
