In FLAC 1.2.0, a new field 'FLAC__CPUInfo cpu_info' was added to the struct FLAC__BitReader. It became useless in 1.3.0 because of various bitreader optimizations. The first patch removes it and also removes FLAC__CPUInfo argument of FLAC__bitreader_init() function. The second patch removes a comment about struct FLAC__BitReader. It...

The first patch adds SSE4.1/SSE4.2 detection. The second patch removes union data in struct FLAC__CPUInfo and replaces it with #ifdefs. Reason: currently it's possible to set or get data.ia32.sse3 value from x86-64 code, etc. It's a potential source of errors (at least that's true for me).

So I've thought of giving more memory: FLAC__bool FLAC__bitreader_init(FLAC__BitReader *br, FLAC__CPUInfo cpu, FLAC__BitReaderReadCallback rcb, void *cd) { FLAC__ASSERT(0 != br); br->words = br->bytes = 0; br->consumed_words = br->consumed_bits = 0; br->capacity = FLAC__BITREADER_DEFAULT_CAPACITY; br->buffer = (brword*)malloc(sizeof(brword) * (br->capacity...

This code is in flux and in the current state the logic probably has inconsistencies that will be fixed in due course. What I am very much more interested in is if the code in the wip/cpu bran...

Hi Guys, The following code in CPU.c (line 155) won't link if you don't have NASM code built even if FLAC__HAS_X86INTRIN is true as FLAC__cpu_info_asm_ia32 don't exists and the else is compiled if there is no dead code stripping if (FLAC__HAS_X86INTRIN) { FLAC__cpu_info_x86(0, &flags_eax, &flags_ebx, &flags_ecx, &flags_edx); info->ia32.intel =

Hi all, I've made a test release for Ogg DirectShow Codecs. You can find it here: http://www.xiph.org/dshow/uploads/Main/oggcodecs_0.80.15035.exe The problem is that I get a HEAP Corruption detected at: void FLAC__bitreader_free(FLAC__BitReader *br) { FLAC__ASSERT(0 != br); if(0 != br->buffer) free(br->buffer); The call stack is: >

I think I've gotten FLAC__lpc_restore_signal() about as good as I'm going to get it. Here's what I have: -a new file, lpc_asm.s, which has the assembly routines -changes to cpu.h, cpu.c, and stream_decoder.c to enable them -changes to configure.in to support the new cpu stuff -a preliminary Makefile.am -maybe something else I'm forgetting Now automake complains that configure.in
