Hello, I'm trying to use "muxing.c" file from the examples. I need to export videos in multiple formats with exact fps, let's say 25. I'm using VLC player to check the real fps. When i pick .avi format as output, it is exactly 25. Hovewer, when i pick .mp4 file, the output video has always slightly different framerate, for example 25.166666. This somehow depends on duration of the video. Short videos can have even more than 26 fps. This does not happen in console tool ffmpeg, just in the file muxing.c. I don't want to use the console version though. I have no idea how to fix this. Would somebody be so kind and help me?
