Description
I was uploading a .m4v file when I noticed that FileZilla indicated its type as "Video (protected)." This was incorrect, as it was an unprotected video file, leading me to believe that FileZilla simply labels all m4v files as protected. .m4v and .m4a simply describe the contents of an MPEG-4 container:
http://en.wikipedia.org/wiki/MPEG-4_Part_14#.MP4_versus_.M4A_file_extensions
I tried grepping the source to see where Video (protected) comes from, but couldn't find anything. Additionally, I'm on Mac OS, and the only place where I can see a file type being grabbed is in filelistctrl.cpp within the member function CFileListCtrl<CFileData>::GetType.
That member uses a function called SHGetFileInfo which appears to be Windows-only, so I'm at a loss for clues as to whether this is a FileZilla problem or within its underlying libraries. Mac OS X's Get Info pane correctly describes the file type as "MPEG-4 Video File."
The information about file types comes from your operating system. The code that ultimately obtains the data is in src/mac/carbon/mimetmac.cpp of wxWidgets, 2.8 branch.
And in fact, all MPEG-4 files are protected. By evil patents.
