VLC is one of the most popular media players out there, loved by millions for its versatility and ability to play a wide range of file formats. However, like any software, it's not without its quirks. One common issue that VLC users may encounter is the error message "VLC can't recognize the input's format" or "VLC your input can't be opened."

If you've come across this error, don't worry - we've got you covered. In this article, we'll explore the possible causes of this error and provide you with solutions to fix it, so you can continue enjoying VLC without any hassle.

VLC can't recognize the input's format

Why VLC Can't Recognize the Input's Format

Why does VLC encounter this error in the first place? There are several potential causes:

1. Unsupported file format: VLC is powerful, but it's not infallible. Some file formats are simply not supported by VLC. If you're trying to play a file that falls into this category, you'll likely encounter the "VLC can't recognize the input's format" error. To address this issue, you can try converting the file to a compatible format using a video converter tool like VideoProc Converter AI.

2. Corrupted or damaged file: Sometimes, files can become corrupted or damaged, making them unreadable by VLC. This can happen due to various reasons, such as incomplete downloads or errors during file transfers. If you suspect that your file is corrupted, you can try repairing it using a file repair tool. Alternatively, if you have a backup of the file, you can try playing the backup copy to see if it resolves the issue.

3. DRM protection or encryption: Certain files, especially those purchased or rented from online platforms, may come with DRM (Digital Rights Management) protection or encryption. This prevents unauthorized access and copying of the content. Unfortunately, VLC may not be able to play files with DRM protection or encryption. In this case, you'll need to use a media player that supports DRM, or look for alternative ways to play the file.

4. File location: If the file you're trying to play is located on a network drive or a remote server, VLC may have trouble accessing it due to network connectivity issues or insufficient permissions. To troubleshoot this, try copying the file to your local storage and play it from there. If it plays without any issues, then the problem lies with the network drive or remote server.

5. Incorrect or outdated VLC settings: Sometimes, the error can be caused by incorrect or outdated settings in VLC itself. To fix this, you can try resetting VLC to its default settings by going to "Tools" > "Preferences" > "Reset Preferences." This will revert VLC to its original settings and may resolve the error.

How to Fix VLC Can't Recognize the Input's Format

Solution 1: Update VLC to the Latest Version

Updating VLC to the latest version can often solve compatibility and performance issues, including problems with recognizing input formats. Here's how you can do it:

Check and update the current version of VLC: Open VLC and go to the Help menu. Then, click on "Check for Updates" to find out the version you're currently using and whether you need to update it.

check VLC updates

Updating VLC ensures that you have the most recent bug fixes and enhancements, which can help resolve issues related to input format recognition.

Solution 2: Convert the File Format to a Compatible One

If updating VLC doesn't solve the problem, you can try converting the file format to a compatible one that VLC can recognize. Here's how you can do it:

1. Use VLC's Built-in Converter: Open VLC and go to the Media menu. Click on "Convert/Save" to open the Convert window. In the File tab, click on "Add" to import the file you want to convert. Choose the output format from the Profile dropdown menu. Finally, click on "Start" to begin the conversion process.

2. Use a Third-Party Media Converter: If VLC's built-in converter doesn't meet your needs, you can use a third-party media converter like VideoProc Converter AI. Download and install the converter on your computer, then follow the instructions provided by the software to convert your file to a compatible format.

Converting the file format to a common one, such as MP4, MKV, or AVI, can make it playable by VLC and resolve the format recognition issue.

Solution 3: Remove the DRM Protection or Encryption from the File

DRM (Digital Rights Management) is a technology used by content providers to protect their intellectual property. It restricts the usage of the file, such as preventing it from being copied, shared, or played on unauthorized devices. Encryption, on the other hand, uses algorithms to convert the file into a format that can only be deciphered with a specific decryption key.

To unlock the file and remove the restrictions, you can use a DRM remover or an encryption breaker. These tools are specifically designed to bypass the DRM or encryption and make the file playable in VLC. One popular DRM remover is TunesKit DRM Media Converter, which can remove DRM from various video formats, including M4V, MP4, MOV, and more. Another option is Any Video Converter, which not only removes DRM but also converts the file to a format compatible with VLC.

Solution 4: Copy the File from the Network Drive or Remote Server to a Local Folder

Another solution to the VLC network stream not working issue is to copy the file from the network drive or remote server to a local folder on your computer or device. This simple step can improve the availability and stability of the file, making it easier for VLC to stream it.

When you stream a file directly from a network drive or remote server, VLC relies on a stable network connection to continuously fetch and play the content. However, if there are any network interruptions or fluctuations, it can cause buffering issues or even disconnect you from the stream entirely. By copying the file to a local folder, you eliminate the dependency on the network and ensure a smoother playback experience.

To copy the file, you can use a file manager or an FTP (File Transfer Protocol) client. If you're using a Windows computer, you can simply open File Explorer, navigate to the network drive or remote server, and drag the file to a local folder on your computer. On macOS, you can use the Finder and follow the same process. Alternatively, if you're comfortable using FTP, you can connect to the network drive or remote server using an FTP client like FileZilla, locate the file, and transfer it to a local folder.

Solution 5: Change the File Extension or Metadata

Sometimes, VLC fails to recognize a file because of its file extension or metadata. By changing these elements, you can make the file recognizable to VLC and get it to play without any issues.

Why does changing the file extension or metadata work? Well, VLC uses the file extension and metadata to determine the format and content of a file. If these elements are incorrect or mismatched, VLC may not be able to understand the file and play it properly.

So, how can you change the file extension or metadata to match the actual format and content of the file? There are two methods you can use: a file renamer and a metadata editor.

To change the file extension, you can use a file renamer tool like Bulk Rename Utility or Advanced Renamer. These tools allow you to rename multiple files at once and change their extensions. Simply select the files you want to rename, choose the new extension, and let the tool do the rest.

Changing the metadata requires a metadata editor like Mp3tag or TagScanner. These tools allow you to edit the metadata of audio and video files, including the file format. Simply open the file in the metadata editor, make the necessary changes to the format and content information, and save the file.

Solution 6: Reset VLC Settings to Default

If changing the file extension or metadata doesn't solve the issue, you can try resetting VLC settings to default. This can help resolve any configuration or preference issues that may be causing VLC to malfunction.

Resetting VLC settings is a simple process. You can do it through VLC's preferences menu or by deleting VLC's configuration files.

To reset VLC settings through the preferences menu, open VLC and go to "Tools" > "Preferences". In the preferences window, click on the "Reset Preferences" button at the bottom. This will reset all settings to their default values。

reset VLC preferences

If you prefer to delete VLC's configuration files, you can do so by following these steps:

  • 1. Close VLC if it's running.
  • 2. Navigate to the VLC configuration folder. The location of this folder depends on your operating system:
    • - Windows: C:\Users\YourUsername\AppData\Roaming\vlc
    • - Mac: /Users/YourUsername/Library/Preferences/org.videolan.vlc
    • - Linux: ~/.config/vlc
  • 3. Delete the VLC configuration folder.
  • 4. Restart VLC. It will recreate the configuration folder with default settings.

By resetting VLC settings to default, you can restore its original functionality and hopefully resolve any streaming issues you were experiencing.
