That means the entire build process of FFmpeg must be done with MSys+MinGW. MSVC++ still does not adhere to the C99 standard, and FFmpeg relies on it, because its developers chose to rely on it. It does not cover Cygwin, since Cygwin is a system that behavesbasically like a unix system, and the biggest problems of using FFmpegoccur with people that aren't very familiar with unix systems.īefore you start, these messages must be clearly understood:įFMPEG DOES NOT BUILD UNDER MSVC++, AND WILL NOT, EVER, BUILD UNDER MSVC++. There you will find all the information you need on this topic in the form of detailed tutorials.The purpose of this wiki is to provide help on everything thatinvolves FFmpeg under Windows.It originated as a step-by-step guide for building under a MSys+MinGWsystem, but now also includes guides for using FFmpeg's libraries inyour projects ( C++, C#). The only thing left to do here is click on 'Check for updates'.įor further instructions on this topic and information on troubleshooting possible issues related to installing updates, please search for separate materials on our website.Open the Windows Update Center by clicking on the appropriate section.To prevent this from happening, we advise you to check for Windows updates and install them. If there are no major updates necessary for the proper functioning of the software, an error may appear on the screen saying that the dll in question is absent, although it is actually working correctly and the problem is actually related to other objects. The dynamically linked library ffmpeg.dll regularly accesses other operating system files during operation, causing certain options or other actions to be executed. Otherwise, you will have to use other fixing methods. If everything went well, the error will not appear again. After these steps are completed, you can immediately continue trying to run the problematic software to verify that it worked.
