Cannot find installation of real FFmpeg (which comes with ffprobe).

This error message usually indicates that the FFmpeg executable or its dependencies are not properly installed on your system, or that the path to the FFmpeg executable is not correctly specified in your application.

To resolve this issue, you can try the following steps:

1. Check that FFmpeg is installed on your system and that the executable path is correctly specified in your application. You can do this by running the command "ffmpeg" in a terminal window, which should display the version number of FFmpeg installed on your system.

2. If FFmpeg is not installed, or if the version installed is outdated, you can download and install the latest version from the official FFmpeg website (https://ffmpeg.org/).

3. If you have already installed FFmpeg but still encounter the error message, you may need to update the path to the FFmpeg executable in your application to match the location where FFmpeg is installed on your system.

4. If you are using a third-party library that relies on FFmpeg, make sure that the library is compatible with the version of FFmpeg installed on your system.

If none of these steps resolve the issue, you may need to consult the documentation or support resources for your application or library to troubleshoot the problem further.
