1) First, start VLC and select “Tools”, then “Preferences”.
2) Within the Preferences window, choose “Inputs/Codecs”.
3) In the lower left corner of the Preferences window, you need to change from “Simple” to “All” in order to see all of the more advanced settings.
4) From the list on the left, select “Demuxers”. You’ll see on the right hand side that the default is “Automatic”.
5) Use the drop down list to select the demuxer to use. “Avformat” tends to work well, however you could try other demuxers if this doesn’t resolve the issue.
6. Click “Save” on the bottom right corner of the Preferences window. Close and restart VLC in order to use the newly selected demuxer.
As a final note, I generally recommend attempting playback of files in multiple players such as VLC, GOM, ffplay, Windows Media Player, etc. You may be surprised how different the playback results can be.
