Method 2: MP4 Video Codec Problem - Install MP4 Codecs for VLC

One of the main reasons behind MP4 video not playing is that VLC cannot identify the audio or video codecs used. Therefore issues such as VLC not playing video but only audio or playing only audio but no video or, at times, both occur. 

If you have tried downloading the latest version of the VLC media player but are still unable to play your MP4 files. You must consider installing the MP4 codec pack for the VLC media player from the official VLC site.

Method 3: VLC Media Player Incompatible File Format Issue

Another main reason why VLC won’t play video is due to incompatible video file formats, where VLC can’t recognize the input’s format. Thereby making it impossible for the user to play MP4 video files on VLC.

The easiest way to fix this issue is by converting the file to any VLC-compatible file format. 

VLC Media Player is renowned for its exceptional capabilities beyond just playing video files.
