Hi Ive cenOS 6 WHM / CPANEL So i Installed FFMPEG in my server. But. Im using a php script for schedule posts on Instagram, but when i try to upload a Video on Instagram Post or Story in the platform. It always give me this error: Fprobe failed to analyze your video file "/home/$user/public_html/assets/uploads/734/najulata-5e00e97bc5abc.mp4". You know what could be the problem? Thanks,
