Q: "Need help when I try to open an MP4 file in Windows Media player, it says Windows Media player cannot play the file, what can I do?"
Windows Media Player is the most common program to play both video and audio files, mainly thanks to its interactive user interface, however, commonly the program presents errors that prevent playing some audio and video formats, I've seen so many times people struggling because they need to play their videos but Windows Media Player cannot play their MP4 file, but chill, there is more than one way to solve these problems and I am here to show you how easy it can be.
Part 1: Why Is My MP4 File Not Playing on Windows Media Player?
Q: "How do I fix the error "Windows Media Player encountered a problem while playing the file?"
Several factors can trigger a problem when you want to play a video in Windows Media Player; depending on the nature of the error, there are different ways to proceed to solve it. Below, I will explain the most common causes and their respective solutions.
Q: "What is a codec?"
Video files are usually very heavy and this can impede sharing them. To solve this problem, there are Codecs, which are responsible for compressing the video and thus converting them into a smaller file. Video players have a library of Decoders, whose function is to process previously compressed files and interpret them while retaining the highest possible quality for the viewer to enjoy the video without even noticing changes in the product.
2. Corrupted File:
Q: "How do video files get corrupted?"
All types of digital files are composed of bytes, this includes videos, and, for this reason, when there is a problem in writing, players interpret these anomalies as a damaged file since it cannot adequately process the information.
3. Permission Problems:
Operating systems offer their users the option to filter access to files, denying or giving specific permission to certain users of the computer, this includes the option to open files. If you do not have permission, you won't be able to open or make any changes to them. Therefore, you must ask the administrator for permission to enable those features.
4. Hardware Problem:
Have you ever noticed any noise coming from your computer? Does the video signal is interrupted from time to time or works slowly, restarts, or displays blue screens of death (BSoD)? These are usually indicators of a malfunction of any of the multiple components of the computer. I will describe some of the most common errors regarding hardware:
Hard Disk: The errors of reading or writing on the hard disk make it impossible for you to open your documents or files (including videos) or they do it very slowly, this usually happens after a long time of using, since, like any component, it has a shelf life.
Solution: You can search a computer component store for a part that is compatible with your computer, for this you will need to find out the model of your Motherboard to know what type of hard drive is right for you.
RAM: RAM problems are usually directly related to the ability of the PC to run and keep open programs stable. It can be due to various problems, such as the malfunction of a module, however, the most common problem is usually the lack of RAM and is quite simple to solve.
Solution: you will have to acquire a new RAM card of greater capacity, for this, you will only need to know the model of your Motherboard since there are different types of RAM and you will need to find out which model is the one that your PC needs, I recommend you ask the advice of your component supplier before making a purchase.
Video Card: Graphics Processing Units (GPU) are the processing units responsible for graphic processes, this includes the reproduction of videos among many other functions. In some cases, processors (CPUs) already include this function as an alternative to the use of a video card, however, if this is not your case, you will have to pay attention to your graphics card as this may be the reason of the issues.
Solution: You must replace the damaged graphics card with a new one but you must consider that there is a wide variety of graphics cards designed for different purposes, there are basic graphics cards, which are affordable and offer enough performance to play videos even on a 4k resolution.
