Hi Nuno,
Yes, this is possible, and we are working on improving the documentation on how
to do it. In the meantime, this is one way to do it:
1. Download FFmpeg built with shared libraries from one of the links below.
2. After unzipping the FFmpeg binaries to a suitable location, configure Qt:
configure.bat <your normal settings> -- -DFFMPEG_DIR=<path to directory
containing FFmpeg include/lib/bin folders> -DQT_DEPLOY_FFMPEG=ON
Note the double '--' that separates configure arguments from CMake arguments.
Once this is done, you can build Qt as usual.
Be aware that he FFmpeg version in the link below is a GPL build. If this is
not suitable for you, I added a link to my unofficial wiki page that describes
different ways to build FFmpeg for Windows. This gives you control over
building FFmpeg without any GPL or non-free components. Among the described
options, using VCpkg is the simplest.
Download links:
FFmpeg for Windows (GPL): https://ffmpeg.org/download.html#build-windows (use
the ones from BtbN, direct link:
https://github.com/BtbN/FFmpeg-Builds/releases). It contains shared libraries
and FFmpeg header files.
