Convert Video for Better Compatibility and Playback
WonderFox HD Video Converter Factory Pro enables you to convert unplayable MP4 videos to VLC supported formats with just a few clicks, thus solving the VLC MP4 not playing problem easily and effectively. Try to fix VLC not playing MP4 issue now.
Firstly, I suggest that you turn to another player, such as Windows Media Player (Windows) / QuickTime (Mac), so as to check whether the video files are corrupt. If they are corrupt, try to download the MP4 files again or you can repair slightly corrupt files using VLC Media Player. Here is how:
Steps to repair MP4 by VLCStep 1: Launch VLC Player; go to Media> select Convert or Save.
Step 2: Add input files that need to be transcoded, and then Hit Convert or Save.
Step 3: Give the file name for the destination file.
Step 4: Select the desired option (Video-H.264+MP3(MP4)) from the profile list.
Step 5: Click Start.
This way you can repair your corrupt files into playable media files.
If this doesn’t work for your file or your files are severely damaged, then you can repair MP4 file by means of some 3rd party video fixers.
But if the MP4 video is played smoothly on other media players, you should just check your VLC media player.
Does VLC play MP4? VLC Plays MP4 and most codecs with no codec packs needed, but if you are using an old version of VLC, maybe the old version does not support the decoding of MP4, which causes VLC not playing MP4, so try updating your VLC to the latest version.
There is not much to illustrate this solution, since it is like "key-to-door" problem. Once you get the key and you can open the certain door. Click here https://www.videolan.org/vlc/index.html or check for update in VLC Media player.
Disable Hardware Decoding LimitationThat shouldn't be an issue, but it might be. Try turning Hardware Decoding off:

Step 2: Go to the Input/Codecs tab, and select “disable” in the Hardware-accelerated decoding drop-down list
