FFExecutableNotFoundError: Executable 'ffprobe' not found during video processing in Gradio

[prsstt]

Description

When attempting to process a video using the application, the execution fails with an FFExecutableNotFoundError. The error occurs within the Gradio video component while trying to validate if the video is playable (video_is_playable), because it cannot locate the ffprobe executable on the system.
