• Android ffmpeg adb shell Unknown encoder 'libx264'

  25 novembre 2017, par IChp

  When I run ffmpeg on android by adb shell, it shows this error :

   Duration: 00:00:12.00, start: 0.000000, bitrate: 30412 kb/s Stream #0:0: Video: rawvideo (I420 / 0x30323449), yuv420p, 352x288, 30412 kb/s, 25 tbr, 25 tbn, 25 tbc
  
  [4;31mUnknown encoder 'libx264'

  I don’t understand what went wrong. It bothered me for a lot of days.
  Can you help me out ? Thanks in advance !
  

  (I pushed the compiled libffmpeg.so to /system/lib and pushed ffmpeg to /system/bin)

  Target : compile ffmpeg with x264, and run libffmpeg.so on android device by adb shell.

  Compiled environment : Ubuntu16.0 32bit,ndk r10b 32bit platform 15, ffmpeg 3.0,x264 latest.

  My configure :

  cd ffmpeg-3.0.9
  
      export NDK=/home/ichp/project/android-ndk-r10b  
  
      export PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt  
  
      export PLATFORM=$NDK/platforms/android-15/arch-arm  
  
      export PREFIX=../simplefflib
  
      export CURRENT_PATH=/home/ichp/project/FREYA-LIVE-LIBRARY-OPTIMIZER-FOR-ANDROID

    ./configure --target-os=linux --prefix=$PREFIX
