The MNG and JPEG2000 plugins are no longer built by default on most platforms because upstream development has stalled and there are known security vulnerabilities. See https://codereview.qt-project.org/#/c/141429/

You can still build them manually if you really want them. Perhaps you could help port the JPEG2000 plugin to https://github.com/uclouvain/openjpeg

I've just upgraded from Qt 5.5.1 to 5.6 using Visual Studio 2013 for 32-bit on Windows 7 and I've found that QMovie fails to load .mng files. Calling QMovie::supportedFormats() just returns "gif". Previously this was working fine.

Is this an intentional change? How can I get round it?
