Encode mp4-video(H264) programmatically with FFMPEG-lib (C++)

It is necessary to implement video encoding in C++ (no audio track. Video only) using FFMPEG. The output will be an mp4-file encoded with the H264 codec. A mandatory requirement is that the video must be played on MacOS (QuickTime Player). (Note: The ffmpeg library comes with an example “encode.c” that creates an mp4 video, but only Windows Media Player Classic can play it. And in fact, this video is an h264 container, and not a full-fledged mp4 file that can be played anywhere) You don't need to build tour own library. You just need to implement encode class ("cpp" file) Pseudocode: #include "myffpmegencoder.h" void main() { _myffmpegEncoderClass myffmpeg; const char *filename = "[login to view URL]"; int width = 1920; int height = 1080; unsigned char *framebuf = new unsigned char[width*height * 3];//rgb frame int frameNumber = 250;//number of frames float fps = 25.0f; float bitRate = 440000; [login to view URL](width, height, fps, bitRate); [login to view URL]("high");//if needed... or other video-quality settings if needed for (int j = 0; j < frameNumber; j++) { //Fill frame buffer by random RGB value for (int i = 0; i < width*height * 3; i += 3) { framebuf[i] = rand() % 255;//R framebuf[i + 1] = rand() % 255;//G framebuf[i + 2] = rand() % 255;//B } [login to view URL](framebuf, j); } [login to view URL](); } Also need the ability to join multiple files of the same format into one common file. Pseudocode: #include "myffpmegencoder.h" void main() { _myffmpegEncoderClass myffmpeg; std::vector<std::string> infilenames; infilenames.push_back("[login to view URL]"); infilenames.push_back("[login to view URL]"); infilenames.push_back("[login to view URL]"); const char* outfilename = "[login to view URL]"; [login to view URL](infilenames, outfilename); } Important: the ffmpeg-library must be the latest version (4.4) (Most of the examples on the Internet are calculated for old versions of the library and do not compile for the new-latest) It would be nice if you did the example-test project on MSVS or Xcode P.S. libx264 is optional, but if you use it, you need to provide lib build parameters for win \ mac \ ios (and other build instructions). Ffmpeg-library building instructions are also welcome.
