FATE sample with a single bit flipped at 0x1e9d, turning the zero-entry index entry into a 1 Gi entry one: http://titan.codemill.se/~tomhar/samples/C0023S01-ohnoes.mxf Or you could just simulate a bit being flipped by changing mxf_read_index_entry_array() thusly: - segment->nb_index_entries = avio_rb32(pb); + segment->nb_index_entries = avio_rb32(pb) ^ (1 << 30); Caveat: I don't know how the multiplication and subsequent cast to size_t behaves on 32-bit. Casting to int and using av_mallocz() SIGSEGVs as expected. /Tomas _______________________________________________ libav-devel mailing list [email protected] https://lists.libav.org/mailman/listinfo/libav-devel
