• How i can fix selected processor does not support Thumb mode `itt gt'

  22 octobre 2017, par w liu

  When I compiled ffmpeg(version 3.3.4) for Android, I successfully compiled out .so, but there was an error while running the project.

• is it necessary in Anaconda for Matplotlib to install ffmpeg for animation saving ?

  2 mai 2018, par Vasyl Kolomiets

  For animation saving I have read some propositions
  1) manual installing ffmpeg this way :

    conda install -c conda-forge ffmpeg

  2) manual installing ImageMagick and changing matplotlib configuration file "matplotlibrc" this way :

  #animation.ffmpeg_args: ''         # Additional arguments to pass to ffmpeg
  
  #animation.avconv_path: 'avconv'   # Path to avconv binary. Without full path
  
                                     # $PATH is searched
  
  #animation.avconv_args: ''         # Additional arguments to pass to avconv
  
  #animation.mencoder_path: 'mencoder'
  
                                     # Path to mencoder binary. Without full path
  
                                     # $PATH is searched
  
  #animation.mencoder_args: ''       # Additional arguments to pass to mencoder
  
  #animation.convert_path: 'convert' # Path to ImageMagick's convert binary.
  
  animation.convert_path: F:\Games\ImageMagick-7.0.7-Q16\magick.exe
  
                                     # On Windows use the full path since convert
  
                                     # is also the name of a system tool.

  where line with pass to installed ImageMagick was added manually

  animation.convert_path: F:\Games\ImageMagick-7.0.7-Q16\magick.exe

  Two questions :
  1 - what way is better for Anaconda ?
  2 - really Anaconda has no better way ????

• 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 PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.8/prebuilt

      export PREFIX=../simplefflib
  
      export CURRENT_PATH=/home/ichp/project/FREYA-LIVE-LIBRARY-OPTIMIZER-FOR-ANDROID
