• Processing3 get "Error=2 No such file or directory" with a file that actually doesn't exist at the first place

  29 octobre 2016, par Tuang Pingfavilunda

  I cannot figure it out what happen to my Processing file. I am trying to use VideoExport library and my Macbook Pro cannot play it, but the Mac-mini is able to do so.

  Before the error happened it is another error=13 permission denied thing, so I messed in the terminal for a while with chmod 777 and finding the file with ls. I don’t know if that may be the reason that caused this happen. FYI, I also installed ffmpeg already.

  And this is the full error :

      java.io.IOException: Cannot run program "/Users/Tuang/Desktop/DMA_WORKS/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde": error=2, No such file or directory

  1) The java.io.IOException : trying to call "/Work1_Facial Muscles/Cam_Rec/sketch_161027a/sketch_161027a.pde" which doesn’t exist for real. It is gone for a long time but seems like the program stuck here.

  2) "basic" is a file name from the Example of the Library. I just use it to test. Surprisingly, Every files that have been saved and changed the name still get the java.io.IOException’s error of the missing sketch_161027a.pde file.

  What I have done :
  1 I have already done the Homebrew thing to install ffmpeg.
  2 I deleted everything of Processing and reinstall it again.

  Any suggestion ?

• ffpyplayer with libx264 error : cannot locate symbol "avio_seek" referenced by "player.so"

  2 décembre 2016, par Gerasimov Mikhail

  Kivy’s ffpyplayer 3.2 can be built with python-for-android’s old toolchain recipe. I also want ffpyplayer to open more video formats so I try to add libx264 for ffmpeg2 recipe.

  I created separate recipe for libx264, here’s how I build lib :

  try ./configure \
  
    --cross-prefix=arm-linux-androideabi- \
  
    --sysroot="$NDKPLATFORM" \
  
    --host=arm-linux \
  
    --enable-pic \
  
    --disable-asm \
  
    --disable-cli \
  
    --disable-opencl \
  
    --enable-shared \
  
    --prefix=$BUILD_x264

  Here’s main part where I add libx264 to ffmpeg2 :

  debug "Activate flags for x264 / ffmpeg2"
  
  x264_CFLAGS="-I$BUILD_x264/include/"
  
  x264_LDFLAGS="-L$BUILD_x264/lib/ -Wl,-soname,libx264.so"

  Everything compiles fine, but I’m getting error when trying to use ffpyplayer on Android device :

  ffpyplayer - ImportError : dlopen failed : cannot locate symbol
  "avio_seek" referenced by "player.so"

  Any idea what can it be ?

  I have no knowledges in compiling libs so I would be grateful if you suggest me way where to go to find reason of this error.
