  25 septembre 2020, par lslboy

  I build a win32 version FFmpeg for get the .dll and .lib file in windows10 follow the https://trac.ffmpeg.org/wiki/CompilationGuide/WinRT document, I executed the command

  


      ../../../configure \
--toolchain=msvc \
--disable-programs \
--disable-d3d11va \
--disable-dxva2 \
--arch=x86 \
--enable-shared \
--enable-cross-compile \
--target-os=win32 \
--extra-cflags="-MD -DWINAPI_FAMILY=WINAPI_FAMILY_APP -D_WIN32_WINNT=0x0A00" \
--extra-ldflags="-APPCONTAINER WindowsApp.lib" \
--prefix=../../../Build/Windows10/x86


  


  everything works well, after that, I execute the command :

  


  make


  


  it shows error :

• Crop layout for Videos using touch for a Video Editor like Video Show or Filmora Go in android studio [closed]

  26 août 2020, par Rayhan Khan

  I am new to the android studio (Java) and video editing application. I am developing a video editor in android studio with FFMpeg Library.

  


  I want to create a crop layout with a rectangle layer on top of it to measure the details like :

  


  

crop video width : 900
crop video height : 500
left distance (x value) : 190
top distance (y value) : 110

                                    1280
