Hi, I tested my own Win32 compile of pre1 and pre2 one or two weeks ago (flac.exe through foobar2000 for transcoding), and the results were as expected: no errors, roughly same speed on my Intel Core i...something mobile, very slightly improved compression performance in comparison with 1.3.1). I didn't test all -1..-8 modes, but I diffed the source code of libFLAC between 1.3.1 and 1.3.2,

In the precompute_partition_info_sums_ function, instead of selecting 64-bit accumulator when the signal bps is larger than 16, revert to the original approach based on partition size, but make room for few extra bits to not overflow with unusual signals where the average residual magnitude may be larger than bps. It slightly improves the performance with standard encoding levels and 16-bit files

In case you would like to check another old patch, I have attached updated patch for seekable stream decoder, originally posted on 09/07/2003. -- Miroslav Lichvar -------------- next

Sending latest version of the patch. Now it can seek in files that have large id3 tag (or any random data) at the end and it won't loop on streams with shuffled frames. -- Miroslav Lichvar -------------- next part

Has anyone tried to build flac with the INTEGER_ONLY_LIBRARY flag set lately? I'm getting link errors on IA32 for the SSE optimizations lpc_restore_signal_16_intrin_sse2 and lpc_restore_signal_wide_intrin_sse41. Looks like a define check is missing since the implementation of these functions is only included when not building for integer. I had to exclude them at libFLAC/stream_decoder.c:408

Hello, Apologies if this has been done before. I just joined the list as this has bugged me for a while. I can compile FLAC 1.1.2 using Visual C++ 6.0 with no problems. However, when I try to compile the CVS source I get: Linking... utils.obj : error LNK2001: unresolved external symbol _snprintf grabbag_static.lib(stream_decoder.obj) : error LNK2001: unresolved external symbol

When using the -p switch during encoding, the encoder should try different qlp predictor precision steps. However, some faulty code was too severely restricting the possible steps. This patch lifts the restriction to match a restriction coded a little further in the process. This doesn't make using -p worth your while, but at least it doesn't create larger files now ---

I have in my working directory the trivial header changes necessary to allow FLAC library functions to be used in C++ programs.

The underscores are wrong. The comment is also correct. Also remove the configure.ac option. Otherwise it tries to compile the windows unicode stuff which POSIX(cygwin) does not understand. --- configure.ac | 2 +- include/share/compat.h | 2 +- src/libFLAC/stream_decoder.c | 3 --- src/libFLAC/stream_encoder.c | 3 --- src/share/grabbag/file.c | 8 +------- 5 files

I have noticed lpc slowdown both in encoding and decoding, not related to new config.h stuff. It seems there is wrong choosing of fastest possible version of lpc function.

I have been running a lot of large compression tests to see how well Martijn van Beurden's new presets do and was once again reminded how real the fragmentation problem still is. To have decent speed it's necessary to run multiple encoders in parallel. In my setup FLAC was compressing four files at the same time and each instance writes tiny bits of data to disk at once. A

Hi all, I was investigating the behaviour of the -p switch of flac. This switch should enable exhaustive search for the optimal qlp coefficient precision, but the resulting files are usually 0.5% larger then when not using the switch.
