BUG: Merging Video Formats Fails Due to Missing FFmpeg Installation

When attempting to merge multiple video formats, users may encounter an error message indicating that FFmpeg is not installed, even if it is already installed on their system. This issue can occur on various platforms, including Windows, and can be triggered by different video links from various websites. In this article, we will delve into the details of this bug, explore possible causes, and provide potential solutions to resolve the issue.

The error message "You have requested merging of multiple formats but ffmpeg is not installed. The formats won't be merged" appears on the terminal when attempting to download and merge videos from any website, including YouTube and Bilibili. Despite having FFmpeg installed on the system, the error persists even after reinstalling it using Winget. Adding another instance of FFmpeg to the Windows environment PATH also fails to resolve the issue.

This bug can be reproduced by attempting to merge videos from any website using a script or tool that relies on FFmpeg. The issue is not limited to a specific platform or video link, making it a widespread problem that affects multiple users.

The expected behavior is for the script to successfully merge the video formats, resulting in a fully merged video file. However, the current behavior is that the script runs but fails to merge the formats, resulting in two unmerged files.

There are several possible causes for this bug, including:

FFmpeg Installation Issues: Despite having FFmpeg installed, there may be issues with the installation that prevent it from being recognized by the script or tool.
Environment PATH Issues: Adding FFmpeg to the Windows environment PATH may not be sufficient to resolve the issue, especially if there are conflicts with other installed versions of FFmpeg.
Script or Tool Configuration: The script or tool may be configured to look for FFmpeg in a specific location or with a specific version, which may not match the installed version of FFmpeg.

To resolve this bug, users can try the following potential solutions:

Verify FFmpeg Installation: Ensure that FFmpeg is installed correctly and that the installation is not corrupted.
Update Environment PATH: Update the Windows environment PATH to include the correct location of the FFmpeg installation.
Configure Script or Tool: Configure the script or tool to look for FFmpeg in the correct location or with the correct version.

The formats won't be merged" is a frustrating issue that can occur when attempting to merge video formats using a script or tool that relies on FFmpeg. By understanding the possible causes and potential solutions, users can take steps to resolve the issue and successfully merge their video formats.
