• Android Studio with javaCv and FFMPEG

  19 janvier 2016, par Calvin Moss

  So I am using the new Android Studio and I am trying to get JavaCV installed in the most basic setup. I made a brand new project with nothing in it, imported (I think unsuccessfully) the JavaCV library and then I am running one of the samples given in the JavaCV repo and I am getting the following error.

  Process: com.example.calvintmoss.dejavid, PID: 1187

  I have read several of the other top posts on the issue but I cannot figure out what is wrong. I downloaded the JavaCV through gradle, then I added the lib and lib/areabi folders. I imported ffmpeg.jar, javacpp.jar, javacv.jar and opencv.jar all to the lib folder. and I extracted all the .SO files from opencv-android-arm.jar and ffmpeg-android-arm.jar and put them in the lib/armeabi just like the instructions on the git repo. I cannot figure out what is going on. Anyone have any ideas ? Also my current setup is. Project->AppModule and then inside of that is where I have my lib and inside of lib i have the armeabi. Does anyone have any info on whats going on ?

• Connect ffmpeg to Visual Studio 2008

  29 avril 2014, par user2274492

  I try to connect ffmpeg to visual c++ like this, but when I type "./configure —toolchain=msvc" I have this error :

  c99wrap cl is unable to create an executable file.

  If c99wrap cl is a cross-compiler, use the —enable-cross-compile
  option. Only do this if you know what cross compiling means.

  C compiler test failed

  config.log :

  WARNING : pkg-config not found, library detection may fail. mktemp -u
  XXXXXX ./configure : line 728 : mktemp : command not found WARNING :

  /tmp/ffconf..ZHENYA.500.5884.c fatal error C1510 : Cannot load language

  What’s the problem ? Or just send me files that you got after compilation with this (I would not have asked, but I fix this two months) :

  ./configure —toolchain=msvc

  make

  make install
