  I'm new to video compression; but I see many of the terms repeated over and over again. I'm wondering what's the difference between x.264 and libx264 and H.264?

• Need assistance to compile X264 in Visual Studio

  8 août 2016, par Vikram Bammanhalli

  I have been trying to open x264 code base in Visual Studio, by creating a separate project for it, but without any success.

  I thought it should have been straight forward. I could build X264 code using MinGW, but I need to edit the code and extract motion estimation code.

  Has anyone compiled/run the x264 from Visual Studio?

  Thanks!
