Video files concatenation v.2

This method doesn't work any more because same_quant or sameq option was removed. So how to make file concatenation preserving quality. I found easier way to do it:

$ mencoder -oac pcm -ovc copy -idx -o out.mov AMBA6924.MOV AMBA6925.MOV

CodeIgniter Framework CMS

Here I've placed some CMS based on CodeIgniter Framework:

• CMS Canvas - Admin section looks exactly as OpenCart, but I don't like it.
• GetNoCMS - Need to try, it has Bootstrap 3 also.
• GoCart - I have already experience to deal with, one of my project based on it, and I've replaced Bootstrap 2 by 3d, also made some chages in catalog, breadcrumbs, SEO stuff, and Russian translation.
• MaxSite - also has an experience to deal with, and converted to Bootstrap 3, but I want something more simple in admin section
• fuelcms - Haven't tried.

That's all I was able to google quickly.
