• Mingw-w64 builded FFmpeg doesn't show any usage information

  26 octobre 2013, par user1240328

  First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously ! The terminal just shows next row. I mean it asks for a next command. But the ffmpeg process is visible in task manager and it writes the output video file what I had requested !

  I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.

  #include 
  
  #include "cmdutils.h"
  
  
  
  const char program_name[] = "hello";
  
  const int program_birth_year = 2013;
  
  
  
  void show_help_default(const char *opt, const char *arg)
  
  {
  
      printf("zxcvbnm\n");
  
  }
  
  
  
  int main(int argc, char **argv)
  
  {
  
      printf("1234567890\n");
  
      return 0;
  
  }

  I want to prevent this behavior.

  I want to make printf working in traditional manner.

  How I build FFmpeg :

  PKG_CONFIG_PATH=/home/developer/workspace/MinGW32fs/lib/pkgconfig/ \
  
  SDL_CONFIG=/home/developer/workspace/MinGW32fs/bin/sdl-config \
  
  ./configure \
  
    --prefix=/home/developer/workspace/MinGW32fs \
  
    --extra-ldflags="-L/home/developer/workspace/MinGW32fs/lib" \
  
    --extra-cflags="-I/home/developer/workspace/MinGW32fs/include" \
  
    --arch=x86 --target-os=mingw32 --cross-prefix=i686-w64-mingw32-  \
  
    --pkg-config=pkg-config   --enable-libtheora --enable-libvorbis --enable-libvpx \
  
    --enable-outdev=sdl --enable-shared --disable-static \
  
    --disable-doc --disable-manpages --disable-podpages
  
  
  
  make

• Tube site like thumbnails for videos- hover over and show rotating thumbnails from the movie

  13 novembre 2012, par slycat

  A lot of adult sites (and mainstream tube sites) have thumbnails of videos, and when you hover over them they cycle through a few differnt thumbnails so you know what is in the video.

  Does anyone know what the name for this is called, and if there is a good library for doing this (either something that captures the images (eg with ffmpeg) or some JS library for this ?
