  3. Solutions for Videos not working with VLC Media Player
    If you encounter problems while attempting to play 4K videos using VLC Media Player, consider implementing the following solutions to resolve the issues.

    1. Enable Hardware Acceleration
    2. Addressing this problem may potentially alleviate issues such as video file lagging and freezing through enhancements in streaming, filtering, and decoding speeds. Prior to implementing this solution, it is imperative to verify that the system is equipped with the most up-to-date drivers.
      Initiate VLC Media Player, which should already be installed on your system. Access the Preferences menu by navigating to Tools> Preferences.

      Check Preferences in VLC

      On the opened page, click Input/Codecs icon and then choose the desired option from the displayed dropdown list under the Hardware-accelerated decoding option.


    3. Enable Hardware Decoding
    4. Configuring or enabling hardware decoding to Automatic, Direct could be another solution to get rid of any problem related to 4K videos. On VLC Media player, navigate to Tools> Preferences. On the Simple References page, select All options under Show settings at the bottom of the page. Then on the Advanced Preferences page, move to Input/Codecs> Video codecs>FFmpeg. In the Hardware decoding dropdown, select the desired decoding options from the list. Finally, click Save.

      Check FFmpeg Method

    5. Modify Video Output Settings
    6. This troubleshooting approach involves a trial-and-error method. Start by adjusting the current video output settings to either Direct or OpenGL and verify if the video plays correctly. To do this, open VLC Media Player, navigate to the Tools menu, and choose Preferences. Then, switch to the Video settings and within the Output section, select your preferred output settings before saving them by clicking the Save button. Finally, launch the 4K video to determine if the problem has been resolved.

    7. Increase the cached value in VLC Media Player
    8. To alleviate stuttering or lag problems when playing 4K videos, you can effectively manage the cached value within the software settings.
      Begin by launching the VLC Media Player. Navigate to the Tools>Preferences menu. Within the Show Settings section, opt for the “All” option. Next, access the Advanced Settings and select the Input/Codecs category. In the Advanced section, adjust the values for File caching (ms), Network caching (ms), and Disc caching (ms) to approximately 10,000 or higher. After making these adjustments, close the VLC Media Player and attempt to play the video once more.

      Note: It is also recommended to select All option against Skip H.264 in-loop deblocking filter option under Input/Codecs feature in the VLC Media Player.

  4. Try converting the file format
  5. If you encounter difficulties playing a video, especially one in 4K or another format, consider attempting to convert the file format as your initial troubleshooting step. Videos are typically created in a specific format according to the device used for recording. However, when users share or view videos on various platforms, they may opt to change the file format to suit their needs. Consequently, video files can undergo format changes as they are circulated and distributed. As a result, certain video files may exhibit unexpected behavior due to alterations in their original formats. To address this, it is advisable to convert such video files into a more compatible format and then attempt playback once more.

    You have the option to transform a video file using numerous free video converter tools. However, if the video holds significant importance and sensitive material, it is advisable to employ a dedicated video conversion tool. An excellent choice for this purpose is the Kernel Video Converter, a dependable and professional solution.
