  9 avril 2024, par 砸石头的西西弗

  A test set which has some different kinds type of sample videos.

• cygwin make errors : ffmpeg compile with ndk

  1er mars 2013, par Bryce

  Recently I'm compiling ffmpeg for android with ndk and I do this as this article(http://vec.io/posts/how-to-build-ffmpeg-with-android-ndk ). configure is right,
  but when I begin to make, it makes errors.
  configure shell :

  It is the character error and I guess it is the windows character(I'm using cygwin), I tried dos2unix but it didn't work. Please help me and thanks for advising.
