Calling ffmpeg from a C++ program

Question

I have seen a similar question here How to wrap H264 into a mp4 container? and Calling a C++ function from a C program but i still need some examples to understand.

1. How can ffmpeg command line be launched from a c++ program to for instance convert a video?

2. Is it possible to use it in a loop for instance where there are a couple of videos in a directory which need to be converted?

I intend converting raw videos in a folder to mp4 but i want to do so using the command line.Relevant link or sample code will be most helpful.

Thanks in advance

Answer 1

1. The same way you would launch any other external program using C++ program.
2. Yes. Enumerate the videos you need, parse accordingly.
