Part 1. Why HTML5 Video Not Found

Corrupted Video File

A corrupted video file can be a frustrating source of the HTML5 Video File Not Found error. When a video file is damaged or incomplete, the browser struggles to process and play it, resulting in an error message. The corruption might occur due to various factors, such as interruptions during file transfers, incomplete downloads, or issues during video encoding.

Ad Blockers or Browser Extensions

The prevalence of ad blockers and privacy-focused browser extensions has introduced an unexpected challenge for web developers. Such extensions are designed to block unwanted content, and occasionally, they may inadvertently prevent video content from loading.

Incorrect File Path

An incorrect file path is among the most common culprits behind the HTML5: Video Not Found error. The browser cannot locate and load the video when the HTML code specifies the wrong location for a video file or if the file has been moved or renamed. It occurs due to typographical errors in the code, changes in the directory structure, or inconsistencies in naming conventions.

File Deletion or Relocation

Suppose a video file has been deleted or moved to a different directory after the HTML code was authored. In that case, the browser faces difficulty locating it at the originally specified location. It can be a common error cause and often occurs when a website’s structure evolves.

File Extension Mismatch

HTML5 video elements require compatible video formats, such as MP4, WebM, or OGG, to be declared in the HTML. If the actual file’s extension doesn’t match the format specified in the code, it can trigger the HTML5: Video File Not Found error. It can result from issues like accidental changes in the file type or mistaken format declarations in the HTML. To fix it, you need a free video converter to convert the compatible video formats.
