Question

I'm using Zeranoe FFmpeg static libraries in my NPAPI plugin. The plugin compiles and links correctly, but when I try to test it with Firefox (I'm using Nightly version) it seems that Firefox is unable to load the plugin.

If I remove FFmpeg functionality from the plugin, it loads normally.

How can I solve that?

Was it helpful?

Solution

Most of the time an issue like this is due to missing DLL dependencies. Try opening the DLL in Dependency Walker and see what is missing.
