Building ffmpeg libraries for Qt about ffmpeg-cpp

this topic helped me to build and use the ffmpeg libraries. Now I will use them to build your wrapper.

I've got it all building but when I try to run the print_info example code. I've got an exception in the constructor of demuxer.cpp:
if ((ret = avformat_open_input(&containerContext, fileName, inputFormat, &format_opts)) < 0)
this result will be less than 0 and throws an FFmpegexception.

this was due to a false path to the sample file. everything is solved now.
sorry for the spam.
