I am running qt video player I made but every time I load a mp4 file or mp3 it gives me this error. MP4:
Warning: "No decoder available for type 'video/x-h264, stream-format=(string)avc, alignment=(string)au, level=(string)2.1, profile=(string)constrained-baseline, codec_data=(buffer)0142c015ffe100176742c015da06025b011000000300100000030320f162ea01000468ce3c80, width=(int)384, height=(int)288, framerate=(fraction)25/1, pixel-aspect-ratio=(fraction)1/1, parsed=(boolean)true'."

MP3:

By the way I am on Centos 7.9.2009 core if that has to do with anything
The answer to this is that media programs should be compiled on windows. Or if your really dedicated to it, include every .h file for gstreamer in your program and carry around those files everywhere the program goes
