H264 codec is extraordinary complex. I have used AI analysis of possible problems. I will attempt to fix problems in DQ VPP branch. This is only warning when somebody would attempt to use this abandoned death branch. 1. Decoder error cleanup can leave an open codec with deleted objects In H264v2Codec.cpp, Decode() jumps to H264V2_D_CLEAN_MEM for errors such as an invalid start code. That label unconditionally deletes: C++ _pHeaderUnsignedVlcDec _pHeaderSignedVlcDec _pBitStreamReader But it does...

Using AI in WP2LaTeX development

Please look at the package https://ftsoft.com.cz/wp2latex/wp2latex.htm and try your document with WP2LaTeX. I have distilled conversion table for all WP4 characters many years ago. Look at the text file WP4a.enc. I have forged WP4 document with all possible characters and observe how they are imported into more modern WP. You can re use this table in libwpd. c cedilla is not listed here. It could mean, that there were many WP4 coding tables spilled across world. It is not possible to imagine the...

I have helped to add decryption with known password (not hacking) of WP MAC files to libwpd. Fridrich Strba gave me encrypted file before many years. I have no MAC to encrypt this myselves. This small code demonstrates, how to read WP6 files, that are encrypted with original encryption. Advanced encryption is not available. There needs to add rejection of new WP6 encryption. I have attached 2 encrypted files than can be decrypted with tool attached. Password is after underscore _ character. C_A.wp...
