Part 2: How to Fix VLC Crashing on Windows

If you are running the VLC Media Player on your Windows system, then you might encounter crashing, lagging, or stuttering issues with it. In this case, I would recommend the following solutions to fix VLC crashing or lagging problems.

Fix 1: Reinstall VLC Media Player

This is the easiest solution in the book that can fix VLC crashing issues pretty easily. For instance, if the VLC Media Player itself is corrupted, then you can uninstall it and later install it back on your Windows. To uninstall VLC, just go to Control Panel > Programs to see a list of all the installed apps. Select VLC from here and click on the 'Uninstall' button to launch the wizard to uninstall the application.

Afterward, restart the computer and go to the official website of VLC again to install it on your Windows PC.

Fix 2: Change the Hardware Acceleration Decoding

Hardware acceleration is a vital component in media players that distributes its load to the GPU. Sometimes, a change in the hardware acceleration decoding can also cause VLC player lagging problems. To fix this, you can go to VLC Player's Tools > Preferences > Input/Codecs > Hardware-accelerated decoding. From here, you select the DirectX Video Acceleration feature or just disable the option altogether.

Fix 3: Turn off Windows Firewall

As stated above, an anti-virus tool or Windows firewall can also cause issues like VLC stuttering or lagging since it can block any important component. If you use a third-party security application, then you can just disable it as of now. In case if you rely on Windows Defender or its native firewall, then just go to its Settings > Windows Defender and simply disable it.

Part 3: How to Fix VLC Crashing on Mac

Just like Windows, you might encounter various VLC Player problems on your Mac as well. While you can also implement some of the above-listed solutions (like reinstalling VLC) on your Mac, here are a few other methods you can try.

To do that, you can go to Finder and click on the 'Force Quit Applications' feature. Alternatively, you can press the Command + Option + Esc keys at the same time. As the Force Quit window will open, select your VLC player and close it from running in the background.

Fix 2: Install A VLC Codec Pack

It has been noticed that Mac is often not compatible with a lot of video formats or codec schemes. Due to this, you might encounter the VLC Media Player crashing on Mac while playing an unsupported file. To fix this, you can just install a VLC codec pack on your Mac that would extend its compatibility for your videos.

Fix 3: Update Your VLC Player

Lastly, if you are running an old or outdated version of the VLC player on your system, then it might cause VLC lagging or stuttering problems.

Part 5: Other VLC Player Problems and Fixes

Apart from the discussed problems like VLC Player not working or a corrupt video, there can be several other issues as well. The following are the three main VLC Player problems that users face with their smart solutions.

Issue 1: VLC Lagging

Too many times, while loading a video, the VLC Media Player keeps lagging. This can happen if the video is of high-definition or too heavy to load by the media player. The lack of video cache or free space on your system can also be a reason for VLC lagging.

Fix 1: Change the File Cache Value

Just like every other major media player, VLC also maintains a cache of the file it is running. If the file is pretty heavy, then you can consider increasing the file cache value to fix VLC lagging. For this, go to its Tools > Preferences > Advanced Preferences > Input/Codecs settings and increase File Cache to around 700-1000ms. You can also improve the value of network caching as well.

Fix 2: Change the FFmpeg Thread Value

If too many threads are running in the background by VLC, then they can make the app lagging or cause a deadlock. To fix the VLC Player lagging problem, you can just restrict the number of threads to two. Go to its Tools > Preferences > Advanced Preferences > Input/Codecs > Video Codes > FFmpeg and change the number of 'Threads' to 2.

Issue 2: VLC Stuttering

Sometimes, while playing a video, VLC Player might start stuttering as well. Ideally, you can just close the application and load the video again. If VLC keeps stuttering, then it means there can be an issue with its settings that you can fix in the following way.

Fix 1: Change the Video Profile

The chances are that the present profile of the video might not be supported by the VLC Media Player. In this case, you can take the assistance of the native feature of VLC to change its profile. Just load the video and go to VLC Media Player's Menu > Media > Convert/Save. From here, you can change the video profile to a compatible format (like MP4) and save the video to the desired destination.

Fix 2: Disable Hardware Acceleration Decoding

I have already explained earlier how hardware acceleration decoding can affect video playback and cause VLC stuttering issues. Therefore, you can go to its Tools > Preferences > Input/Codecs section and simply disable the hardware acceleration decoding feature from here. Afterward, try to load the video again and check if VLC is crashing or not.

Issue 3: VLC Green Screen

While playing a video on VLC Player, you might get a green screen instead. An issue like VLC grey or green screen happens when there is a problem with its output coding, or the video is missing some frames.

Fix 1: Change the Output Scheme

To provide a better viewing experience, VLC provides different output modules that we can switch as per our requirements. Though, a change in its output module can also be a reason for the VLC grey/green screen. You can fix it by visiting its Tools > Preferences > Advances Preferences > Video > Output Modules. You can switch between different modules here or just select a more compatible format like Direct3D or OpenGL to resolve this.

Fix 2: Drop Late or Corrupt Frames

If a video frame has been corrupted, then you might get the VLC green/grey screen instead. This is because VLC would not be able to play the respective frame and will display a green screen instead. To fix this, you can just choose to drop the missing or corrupt frames instead by visiting its Tools > Preferences > Advances Preferences > Video option. From here, just enable the feature to drop late frames and skip corrupt frames.
