--enable-avresample is deprecated however L-SMASH-Works still depends on it

[hydra3333]

ffmpeg's --enable-avresample is deprecated, however L-SMASH-Works still depends on it,
eg without --enable-avresample the following build error is thrown.

Would you please be able to fix this so it no longer depends on a deprecated ffmpeg build option ?

To support both ffmpeg and libav, I currently have plan to make a global configure and a global makefile, and a lib archiving objects consiting of source files in common directory.

OK, thank you.

Hello, is there any progress on this? I still cannot build L-Smash for vapoursynth, same problem as OP.
