3a84725d31 use __linux/__unix instead of CMAKE_C(XX)_FLAGS 
this allows the user-specified CFLAGS/CXXFLAGS to take effect.

assume that all platforms supporting C++ in 2021 also support stdbool.h.

7fc569949e Increase JPG/MP3 in-memory threshold 
- maximum size 512 MB instead of 64 MB
- verbose output if JPGs are too large for in-memory (and packJPG is used as fallback)

b422204c55 Disable brunsli logging 
- with enabled logging, brunsli is too verbose and will spam precomp's output

9644f76d71 revert bit shift fix 
- reverted because 7 * section_size_bytes will never be greater than 64 if the function is used correctly, so the code is correct

d5a0d774d3 Use "use_brotli" flag 
- if not set, metadata gets copied instead of compressed
 2019-10-22 12:20:43 +02:00

006a5849b1 Add "use_brotli" flag 
- brotli compression of metadata will be optional, so a flag is added to both encoder and decoder
- precomp will pass the flag to Brunsli[Decode/Encode]Jpeg

041d6b28e7 Update preflate to v0.3.4 which adds a task pool to give nice speedups 
for large deflate streams.
However, preflate hogs much more memory now than anticipated. Needs to
be investigated.

677e8c5fb0 Add fix from PackMP3 master. 
Without this, some MP3 streams might crash on reconstruction.

78b918dc18 - update to preflate v0.3.2 (bug fix) 
- add switch -pfverify to force preflate to verify its result and store
  mishandled deflate streams in files

c48a0b5c4c Add command line options to set LZMA literal compression flags (-llc,

4772a9c37b Update to preflate v0.3.1 
Splits up large deflate streams to blocks responsible for ~2MiB of
uncompressed data each. This reduces memory pressure a LOT.

1cfd08a703 [WIP] First test of liblzma executable filters 
- See issue #75
- Filter maximum is 4, so up to 3 filters + LZMA2 can be used
- X86+PPC+ARM could be a good default
- TODO: Command line parameter so set or disable filters

- Changed VS settings, so unfortunately there are some tab/space changes in here, too.
