Comment (by shenlebantongying):

 After this change
 (https://git.ffmpeg.org/gitweb/ffmpeg.git/blobdiff/49726a922fd2b358feb7753488d415180da5121c..4a0e1cfc6f33d152e007849f6de7028d651de2af:/libavcodec/speexdec.c)

 The test files above can be fixed by hardcoding `frame_size` to 640 (which
 I know isn't a proper fix):
