P-frame duplication in avidemux 2.5.4 on Mac OS X
I had thought it wasn't possible to install a version of avidemux that was old enough to use for datamoshing on Mac OS X. It turns out that that's wrong, and avidemux 2.5.4 works just as well as 2.5.6 for datamoshing on Mac OS X! A .dmg was never distributed for 2.5.6, but one was distributed for 2.5.4 and it's easy to get working on Yosemite (and allegedly Lion). Here's how:
- Go to http://sourceforge.net/projects/avidemux/files/avidemux/2.5.4/
- Unpack it and then drag
avidemux2 to your Applications folder. (If you want, you can then drag the avidemux2 from your Applications folder onto your Dock for easy access--but only after first putting avidemux2 into your Application folder from the unpacked .dmg.)
- Navigate to the Applications folder, right-click on avidemux2, and click "Show Package Contents".
libiconv.2.dylib from the Contents/Resources/lib folder. (Note: My
libxml.2.dylib was actually named
- Open avidemux2. It should work!
Credit to this old Superusers post for having the solution. Happy moshing!
Don't know how to datamosh? Here's a decent tutorial. I'm also working on a very comprehensive tutorial that I'll post on the forum in the near future.
