How to Fix Videos Not Playing on Different Scenarios (SNS, iPhone, PC, Broswer, More)

Part 1. Why Videos Won’t Play on Computer and Mobile

You might wonder: “Why are my videos not playing on my iPhone?” or “Why won’t my computer play videos?” There are several reasons why video unable to play issues happen. Let’s see them:

• File Corruption or Damage: Files can become partially downloaded or corrupted due to interruptions or bad storage sectors. A video unable to play error often appears because the file headers are unreadable.
• Unsupported Formats or Codecs: Sometimes no videos are playing because your player doesn’t support the video format (e.g., .MKV, HEVC). Missing codecs cause errors like can’t play video.
• Outdated Software: Old versions of your video player, browser or mobile OS might struggle with newer video formats.
• Hardware or Graphics Issues: Weak graphics cards or outdated drivers might be the reason why won’t my videos play smoothly on PC.
• Storage or Cache Problems: Limited storage on mobile or overloaded browser caches can trigger playback failures.
• Browser Extensions: Extensions like ad blockers can interfere with video loading, especially on platforms like YouTube.

Whatever your error message says “video unable to play” or simply leaves you staring at a black screen, you need to identify the root cause for a proper fix.
