The below is the terminal log when I ran vlc. Could any one help me whats the issue here.

I'm able to hear audio from youtube in chrome but not through vlc when i play file. Video is fine.

The issue started after I tried to check a usb web cam on the pi. Tried rebooting and upgrading no luck.

  • VLC is very laggy. SMPLAYER is a good player in Raspbian. – Sohan Arafat Jun 11 at 9:13
