So here I was trying to install Stremio which is a video streaming program. And this was linux- a debian VM install. And I successfully installed the deb file I could download from their website. But it would not run. When I started it from the terminal I got a library version mismatch error for libx264. The version stremio was looking for was 152. I had 148 and 155 on the system but stremio would not take them.
So I went ahead and tried to cheat my way via a symlink. The symlink to 155 would not work because of some change in one of the functions. But when I tried it out with 148, voila!! It worked!
