Over the past 2 days I found that the VLC install on my computer was suddenly having issues playing some of the video files on my computer. Initially I thought that it was a problem with the video file, then I realized that this was also happening with videos that had be playing fine earlier. When I ran vlc from the command line to play the problem video it gave the following output on screen when it crashed:<\/p>\n

A google search told me that a possible solution was to disable hardware acceleration in the Video settings but that didn’t fix my problem. So I took a look at the kernel.log<\/em> file in \/var\/log<\/em> and I got the following error when the program crashed:<\/p>\n

Spent about an hour searching for the solution using the details from the kernel.log<\/em> but got nowhere. Finally I found a forum post where one of the solutions offered was to remove the vlc configuration files, since I didn’t have any other bright idea’s I renamed the vlc config folder by issuing the following command:<\/p>\n

mv ~\/.config\/vlc ~\/.config\/vlc_09302020<\/pre>\n
Then I started vlc and just like that everything started working again. \ud83d\ude42 Not sure what caused the settings to get borked in the first place but the issue is fixed now so all is well.<\/p>\n
