Hello, Patch in attach, change codeword bits writing by replacing PutBitContext, and use instead uint64_t bit_buf Also remove byte buffer length check
encode_codeword func have two version now - one for dc coeff and run coeff (same as previous encode_codeword func) - one for level coeff who also integrate the "IS_NEGATIVE(val)" bit writing encode_codeword func code is reorganize in the first part, calculate codeword value and number of bits for this value at the end, write the codeword in bit_buf, and if bit_buf is full, write it in dst buf. Pass fate test for me (X86_64 os X) also tested, on real samples. Md5 hash of the target file doesn't change for me Speed improvment on X86_64 : test file 1 : 140 -> 154 fps test file 2 : 55 -> 62 fps Not tested on big endian and X86_32. Fate test cmd : make fate-vsynth3-prores;make fate-vsynth2-prores;make fate-vsynth1-prores;make fate-vsynth_lena-prores SAMPLES=fate-suite/ Comments welcome Martin
