VLC does not support the audio or video format "undf"

After downloading a Video from Youtube this Pop Out on my VLC

No suitable decoder module:
VLC does not support the audio or video format "undf". Unfortunately there is no way for you to fix this.

VLC can't play the video the Video was not corrupt and downloaded completely.The 'undf' codec type for VLC just means that VLC did not recognize the format or, in other words, it is not one of the supported formats. 

"undf" is simply an abbreviation for "undefined" and is not a file format.

I had the same case with a video from youtube that I was trying to download using Google Chrome and a known download manager   ( IDM )which saved the file as .WEBM.

 I found the problem that  the Google Download Manager extension (add-on ) Don't know if it makes sense is not showing what kind of format you want to download. It only shows separate audio track and video track  only  see image below.

However, I tried with Firefox's add-on  Download Manager  Helper ( IDM ), and it saved the file as .MP4 , FLV , 3GP and it opened successfully.

This are  File example.......
