Instead it essential means anything between a set of ' Luckily the specifications say 'block' of code, which does not mean function or something similar. This will generate an error on the variable 'pix' because it is declared mid way through a block of code. buffer: 2 chroma, 3 luma (rounded to 4) because deblocking goes beyond the top of the mb So most errors will be due to code such as the following: Straight of the bat most of the errors that Visual Studio will spit out about the x264 code will be a result of this issue (although the error codes don't do you any favours in realising this). Most of the issues are a result of C89 requiring all variable declarations to be altogether and the start of each logical block of code. Luckily changing x264 for be MSVC compatiblilty is rather straightforward. x264 however still requires some manipulation in order to get it compile under MSVC's mostly C89 world.
C99 is something Microsoft have been neglecting for many years but with the 2013 updates it is a lot closer. For those with Visual Studio 2013 then compiling many similar open source projects becomes a lot easier due to the addition of partial C99 support. Visual Studio) then that can actually be done rather simply. And even from within these shells they only support gcc (MinGW on Windows) based compilers.īut for those wanting to compile x264 natively on Windows using the native Windows build chain (i.e. These don't run natively on Windows and generally requires an emulated shell such as MSYS or Cygwin. One downside of the x264 project (much like most open source projects) is that the default build tool is a gnu make style build chain. So anyone who wants to get their hands on it can do so easily. And it is completely free and open source. So in the world of h264 video encoding x264 is probably one of, if not the best. And if you havnt then you should have at least have heard of h264 (and if you still havnt then this post is probably not for you) which is the standard name for the video codec that the x264 encoder implements. For anyone who has ever done any video encoding (or just watching for that matter) will probably have heard of x264.
