I tried to find the binary distribution (since I am curious about the EULA of
the wmdrm library that is used at runtime, see libavcodec/wmdrm_wrapper.h). On
http://www.samsungsupport.com/650/, I found a license pdf (containing LGPL and
others for other used projects), but no EULA for the firmware updates and no
binary containing FFmpeg code (so I could not verify the actual license).

Pastebin misses the following:
In libavcodec:
Paul Kendall's LATM code (which works for libfaad, that's why I would like to
check the binary)

In libavformat:
A wrapper for libmms (I could not find the libmms sources btw): mms.c
dlna.c which needs missing DLNAReader.h to compile - not compiled (dnla on wp)
https.c and ssl.c (a wrapper for libssl) - not compiled
vudu.c and vuduapi.c - not compiled (www.vudu.com)
widevine.c and WR_wvutil.h (www.widevine.com)

widevine is compiled into the (also provided) libavformat.a and libavformat.so,
but contains missing symbols.
