i dont dispute that, what i meant was more high level that is, "what that code should be doing", i think is different from skiping the code > The best we can do over my change is to make wrap_bits == 63 work by > changing the line from 2LL << (wrap_bits - 1) to 2ULL << (wrap_bits - > 1). av_compare_mod takes a uint64_t in this position so that should be > okay. How does that sound? I think that could end with the correct result thanks [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB If a bugfix only changes things apparently unrelated to the bug with no further explanation, that is a good sign that the bugfix is wrong.
