Comment (by reimar):

 You can just add those symbols to the list of symbols that should be
 However this case is more problematic than just using a private symbol:
 This array is only initialized when dsputils are initialized, which the
 application has no control over at all which will cause issues even with
 their own FFmpeg copy.
 This is likely to cause serious and hard to debug issues, like the
 deinterlace filter breaking completely when using it on a raw uncompressed
 video but working fine when playing a H.264 file.
 The array is trivial, so except for wasting some memory it should be a
 problem for the program to have its own copy of it.
