Ross, since you added the reference to the Expat license, did you plan on
actually adding it as well? It being missing breaks at least our license
handling. After writing this, I went digging in ffmpeg, and it seems that the
Expat license (only mentioned by name, there is no actual license text) is
only used for a test image (reference.pnm), which does not end up in any
package. So to me it seems as this does not need to be included in LICENSE.
Also, given the long list of licenses that are now in LICENSE, what packages
are actually expected to use those licenses? AFAICT, all packages that are
explicitly listed in the recipe either use GPLv2+ or LGPLv2.1+. The default
licenses only seem to be used for, e.g., ffmpeg-dev, ffmpeg-dbg and
ffmpeg-doc, which seems weird.
More weirdness, LIC_FILES_CHKSUM lists GPLv2, GPLv3, LGPLv2 and LGPLv3, but
neither GPLv3 nor LGPLv3 are used in LICENSE. And there are no references for
any of the newly added licenses.
