[vlc] I can NOT watch videos anymore using vlc ...

[Albretch Mueller]

or any other video utility.

Sound, however, seems to be fine. I just don't see the graphic part
of the video

I even tried using ffmpeg to record as a video my own screen which I
can see just fine, but when I tried watching it using vlc, I couldn't

this is what I got:

$ vlc --verbose 1 "PRISMWhistleblower_FromGuAmRM-16x9.mp4"
