I am trying to play a .mov file in VLC player, I am able to hear the audio but not able to see the video content. In the top left corner i see the vlc icon and then VLC (Direct3D output), Any suggestions please
Within VLC, try pressing
Control+I (View Media Info)
looking at those tabs can show you all sorts of interesting information at the file.
As was mentioned, MOV is just a container - what is embedded inside it is what is interesting. There should be at least two streams, one for the audio and one for the video. Chances are that if you can't see the video then it is probably either a poorly encoded/broken stream or that very rare file that VLC just can't play. It would be helpful to update your question with what VLC sees as the streams (and their details):
I am going to assume other video files play just fine in VLC and this is a problem specific to one file? Does that same file play just fine in Quicktime?
