7-Zip using the Fast LZMA2 library

7-zip-fl2's Issues

Dictionary size

Can't you set the dictionary size, like it's possible in some of the GUI versions?

How flzma2 decode ?

In file /CPP/7zip/Compress/Lzma2Encoder.cpp
HRESULT CFastEncoder::FastLzma2::AddByteCount(size_t count, ISequentialOutStream *outStream, ICompressProgressInfo *progress)
{
dict_pos += count;
if (dict_pos == dict.size) {
size_t res = FL2_updateDictionary(fcs, dict_pos);
CHECK_H(WaitAndReport(res, progress));
if (res != 0)
CHECK_H(WriteBuffers(outStream));
res = FL2_getDictionaryBuffer(fcs, &dict);
while (FL2_isTimedOut(res)) {
if (!UpdateProgress(progress))
return S_FALSE;
res = FL2_getDictionaryBuffer(fcs, &dict);
}
CHECK_S(res);
dict_pos = 0;
}
if (!UpdateProgress(progress))
return S_FALSE;
return S_OK;
}
You didn't call FL2_compressStream() to compress src data.
Can FL2_getDictionaryBuffer also compress data？
You use basic Flzma2 API to compress. Did you change the FL2_compressStream() format？
Did you change the format to support the decompression of lzma2 OR Can FL2_compressStream() compressed data be decompressed by Lzma2Decode() .
