Despite its capabilities, VLC might display the ‘Unable to open the MRL’ error when accessing remote files or streams. This issue can stem from internal firewall blocks or remote host problems. Stick around as we guide you through resolving this error.
Getting Started with VLC
To start using VLC, download it from the official website and follow the provided instructions. After it is installed, you can run VLC and play audio or video files on your computer.
What Is an MRL File?
MRL stands for media resource locator, a URI used to uniquely identify and locate a multimedia resource. It is used by the VideoLAN and Xine media players, as well as the Java Media Framework (JMF) API.
A media resource locator (MRL) is a string of characters used to identify a multimedia resource or part of a multimedia resource. A MRL may be used to identify inputs or outputs to VLC media player.
The MRL syntax is:
[[access][/demux]://]URL[#[title][:chapter][-[title][:chapter]]] [:option=value …]
VLC, for example, supports the following MRLs:
- dvd://[⟨device⟩][@⟨raw device⟩][@[⟨title⟩][,[⟨chapter⟩][,⟨angle⟩]]]
- vcd://[⟨device⟩][@{E|P|E|T|S}[⟨number⟩]]
- http://⟨server address⟩[:⟨server port⟩]/[⟨file⟩]
- rtsp://⟨server address⟩[:⟨server port⟩]/⟨stream name⟩
- Several media players also support Video4Linux as v4l:// and v4l2://
What Is VLC is unable to open the MRL file Error?
Often the case, the “Your input can’t be opened. VLC is unable to open the MRL” error message occurs when trying to open a file or a stream that is not physically located on the local computer, but comes from external storage drive, online site or another server. Typically, we may encounter different VLC MRL errors based on the file types like “VLC is unable to open the MRL ‘dvd:///…'”, “VLC is unable to open the MRL ‘rtsp://…'” and “VLC is unable to open the MRL ‘https://…'”.
Here are some examples of the actual error messages:
Your input can’t be opened:
VLC is unable to open the MRL ‘file:///D:/pa/PortableApps/gPodderPortable/App/gPodder/byb0040_h264m_1280x720_1872.mp4’. Check the log for details.
Your input can’t be opened:

VLC is unable to open the MRL file error can trigger the failure of the VLC media player when the application was unexpectedly blocked. It can be because of the media source that prevents the player from accessing the needed file due to additional errors. It might also happen because of issues with system files or functions.
The problem occurs with Blue-ray, DVD, and Streaming, but the main issue is with the VLC player, and it seems that users keep complaining about it even though the program already received upgrades. People inform that the video playing is unsuccessful, and this frustrates them when the issue repeats again and again.
It is possible that the error is the result of an internal firewall roadblock or a program error. It is most likely the fault of this application itself but can be triggered by the error with the remotely located content. You can take some steps to ensure that the VLC is unable to open the MRL file error caused by a particular problem.
If the problem is related to the Windows system and its issues, updating the operating system can help since there are many issues caused by the faulty upgrade or the version that requires patches. Another useful method that can help deal with these errors – system file corruption check. When cyber infections and other issues with the machine trigger alterations to data in the system folders, functions can fail. Attempt to use a trusted system cleaner or optimization tool to fix any found problems and prevent further damage to your computer.
This is one of the methods to troubleshoot or even fix the VLC is unable to open the MRL file error on Windows machines. Other steps below can show how to ensure the proper connections and possibly solve the issue with the media player by altering settings and preferences.
What Causes VLC is unable to open the MRL file Error?
Note that depending on the file type you want to open, the error message will have slight variations. For example, the error might say, “VLC is unable to open the MRL’ DVD://[file name]’. Check the log for details. Other prefixes may include ‘rtsp://[file name]’, ‘https://[file name]’, and so on.
The error could be caused due to ownership issues, obsolete VLC client, an overprotective Firewall, and incorrect URL source.
The “VLC is unable to open the MRL file” error occurs when VLC tries to open a file or stream video that is not physically located on the local computer but elsewhere and can’t be accessed. For example, the file you may try to open is located on an external storage drive, online website, or another server. If VLC can’t access the file you ask it to access — you will get this error.
Since the error occurs when a remotely located content is not accessible for one reason or another, there are a series of steps that you can follow in order to pinpoint the source of the problem. If you’re seeing the “VLC is unable to open the MRL” error when you try to play a video or a stream, follow the steps down below to get the issue resolved. Below you have a collection of methods that other users have used in order to get the issue fixed. Please follow the methods in order until you stumble upon a fix that gets the issue resolved.
What to Do If You’re Getting VLC is unable to open the MRL file Error?
Before performing any of the recommended troubleshooting steps listed below it’s best to restart your computer first. This action refreshes the operating system and removes any corrupt temporary data that could be causing the problem.
If you’re trying to access a remotely located file but get this error, then you can try the fixes located below. Note that not every method will work in your particular case, so go down through the list and try each one until you find the one that does the job for you.
Step 1: Make sure that the source is working.
Before you do anything else, it’s important to make sure that the source you’re trying to access is actually working. Since the error mostly occurs with streams and other URL-based content, go to File > Open Network Stream and copy the URL that you’re trying to access from there.
Paste the URL into your browser (or another video player) and see if it begins playing. If the network URL doesn’t work in other applications, it’s very likely that the issue doesn’t lie with your VLC player version but with the source instead.
In the event that the source functions in your browser or in another media player, continue with the next methods below.
Step 2: Tweak your Firewall settings.
The majority of occurrences with the “VLC is unable to open the MRL” error that are not the result of a broken source are actually caused by a firewall setting. Overprotective firewalls (especially 3rd party solutions) can end up blocking the necessary ports needed by VCL to stream the source successfully.
Of course, depending on your 3rd party firewall, the steps preventing your external antivirus from interfering with your content streaming will be different. If you’re using AVG, you can remedy this issue by going to Firewall > Tools / Firewall Settings, then select Applications from the left pane. Next, move over to the right pane and change the action assigned to the VLC media player to Allow for all.
Check if the VLC is unable to open the MRL file issue still occurs. If it doesn’t then turn on the firewall and add VLC to its exception list.
- Type Firewall in the search bar then click on the Firewall app that appears.
- In the resulting Windows Firewall window, click Allow an App through Windows Firewall.
- In the Allowed Apps window that appears, click the Change Settings button, and then select the check box for apps on your computer that you want to allow to communicate over the Internet without being stopped by Firewall.
- Click the Private and Public check box to narrow down whether you want just networks that are secure to allow this communication, or also public and non-secure networks to do so.
- Click OK and then click the Close button to close the Windows Firewall window.
Note: If you’re using a different antivirus, you’ll need to find specific steps related to the security suite that you’re using.
If you’re having trouble finding the equivalent steps for the 3rd party antivirus that you are using, a simpler solution would be to simply get rid of the 3rd party firewall and use the built-in solution. Windows Defender firewall is commonly regarded as less likely to cause conflicts with VLC, compared to some third-party firewalls.
Here’s a quick guide on how to uninstall your 3rd party security suite and use the built-in firewall:
- Press Windows key + R to open up a dialog Run box. Next, type “appwiz.cpl” and press Enter to open up the Programs and Features window.
- In the Programs and Features window, scroll down through the application list and right-click > Uninstall on the 3rd-party firewall suite that you’re using.
- Follow the on-screen prompts to remove the external firewall from your system.
- Reboot your computer. At the next startup, Windows Defender firewall will enable itself automatically.

I tried all the above remedies to no avail – I was still getting random “MRL” errors on some, but by no means all MP4 videos loaded on my NAS. This suddenly started in February this year, after years of good service. Same problem on 3 different laptops. My cure? Ditch VLC and use SMplayer – problem fixed in a jiffy. So long VLC and thanks for all the fish…
