Michael Niedermayer c0c6b68ddb tools/target_dec_fuzzer: assume that discarded audio packets produced max samples 
We do not know how many samples these produce as its not exported.
Alternatively we could export that but as long as its not we better
assume its more than 0 as otherwise the thresholds would not work
