Thank you very much. I noticed this error means vdsp functions themselves
can't call, but don't know how should I fix it.
By adding "-framework Accelerate" to Libs line in rubberband.pc, the error have
gone!!
(On macOS, vdsp functions are defined in Accelerate.framework)
- Libs: -L${libdir} -lrubberband
+ Libs: -L${libdir} -lrubberband -framework Accelerate
I'm so happy!!!
P.S.
I have tested rubberband function as follows:
./ffplay -i ~/Movies/test.mp4 -af rubberband=tempo=2
It's fun!!!
