Inconsistent input_frames_used/output_frames_gen among the numbers of channels #206

Open ss3git opened 9 months ago

ss3git commented 9 months ago

SRC_DATA.input_frames_used/output_frames_gen are not consistent when (only) channels are different.

How to reproduce: use the simple_test here. https://github.com/ss3git/libsamplerate/blob/InconsistentOutgen/tests/simple_test.c
