2 years ago Hi, thank you for finding and reporting this issue. It seems some frames have unexpected data leftover outside of frame dimensions. these leftovers also seem consistent (all frames in sequence have the same leftover) I have now fixed the crash by treating such cases as warning (instead of crashing).

Nutcracker crashes when decoding SAN files from the CMI demo (DEMOVID1 and DEMOVID2) and the SAN file extracted from the Grim video demo.
I was trying to dump the Grim video to png when I encountered this, so I tried it with the CMI demo san and that too crashed. Files from the release version of CMI seem fine.
GRIM.SAN here. DEMOVID2.SAN here.
With GRIM.SAN extracted from the demo exe: It dumps up to FRME_02264 then:
