I have a case that becomes really non deterministic

for i in `seq 10` ; do ./ffmpeg -v 0 -bitexact -i mszh-zlib/monika_zlib.avi -bitexact  -t 1  -f crc - ; done
CRC=0x52e2e323
CRC=0x747761ba
CRC=0x747761ba
CRC=0x52e2e323
CRC=0x9d872a4b
CRC=0x5f5cacfd
CRC=0xda55c458
CRC=0x2eccf1c8
CRC=0x747761ba
CRC=0x1a4775bd

sample from here probably: https://samples.ffmpeg.org/V-codecs/mszh-zlib/

before:

for i in `seq 10` ; do ./ffmpeg -v 0 -bitexact -i mszh-zlib/monika_zlib.avi -bitexact  -t 1  -f crc - ; done
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
CRC=0x192dc994
