VLC MP4 Solution - Convert MP4 to VLC more Supported Format

Symptoms in Playing MP4 in VLC

Does VLC play MP4 video? According to the official website, VLC does support MP4 files. However, sometime we still fail to play MP4 in VLC just like the following:

  • I recently downloaded an mp4 torrent file, it contains two mp4 clips and main movie is mp4 as well. VLC player will play the two shorter clips no problem but will not play the main movie.
  • MP4 will not play on Windows Media Player (Vista) so I downloaded VLC. Unfortunately they won't play properly on that either.
  • I'm having a bit of a trouble playing HD encoded MP4 files using VLC Media Player. Whenever I play a video using VLC, it makes a file looked like it's damaged or something. But when I use Windows Media Player, it seems to be okay.

Reason and Solution

Reason 1: The MP4 video is fake or corrupt

Reason 2: Maybe the VLC "video output modes" is set wrong.

Solution: In this situation, you need to configure X Server correctly:

Open VLC Player, then go to Tools > Preferences

In the Video tab:

  • Set the Output drop-down menu to X11 video output (XCB).

Finally click "Save" to save your changes and restart VLC player.
