merge before #43761

no longer needs ffmpeg libraries, replaced with gstreamer. extract throws an error with exiv2 plugin when trying to extract stuff that's not an image, which is apparently intentional (line 605 of exiv2_extractor.cc)

The exception exists in current version. But it's bad!

yeah, I think it's a little silly how they made the exiv2 plugin... throw an exception instead of simply not run when it runs on a file that can't be loaded by exiv2. it can be worked around in extract by either not using -i and ignoring the error that pops up on its thread or using -n -l <plugins_you_need> for the specific plugins one needs for a file. in any case, it's an intentional design decision, but is it our responsibility to patch it out? I'm not sure
