I have also asked this question on stackoverflow (http://stackoverflow.com/questions/8694676/compiling-64-bit-flac-libflac-in-os-x-lion), which you can answer if you're interested in reputation points. I am very unfamiliar with compiling C/C++ source of this size, and I'm having trouble debugging the issue. Basically, in the root folder of the FLAC bundle, even if I use the flags

Despite being documented as the place for submitting bug reports and patches, it seems like the sf.net bug tracker isn't get much attention, so here it is: http://sourceforge.net/p/flac/bugs/400/ During x86-windows builds using mingw or mingw-w64, nasm complains: nasm.h:83: warning: COFF section names limited to 8 characters: truncating I think the section .note.GNU-stack stuff aren't

They are not needed since the section is defined in nasm.h. --- src/libFLAC/ia32/bitreader_asm.nasm | 4 ---- src/libFLAC/ia32/cpu_asm.nasm | 4 ---- src/libFLAC/ia32/fixed_asm.nasm | 4 ---- src/libFLAC/ia32/lpc_asm.nasm | 4 ---- src/libFLAC/ia32/stream_encoder_asm.nasm | 4 ---- 5 files changed, 20 deletions(-) diff --git

Previously I wrote that precompute_partition_info_sums_32bit_asm_ia32_() only makes encoding slower. Now I managed to compile flac with GCC 4.8.1, with this function enabled and disabled. NASM was enabled, SSE intrinsics disabled. Then I added -msse option (so that all C code was compiled with -msse), then -msse2 and so on. Input file for test: 44.1kHz/16bit/stereo; best compression mode (flac

Hi all, It sees that the most serious bug in the flac bug tracker: https://sourceforge.net/p/flac/bugs/413/ has been fixed in git. This fix alone is worth a new release so its time to work towards one. Things I need to do for this new release: * Deal with all current patches on the mailing list. * Review all bugs reported against 1.3.0 on the sf.net. * Testing and coordination of testing

It turns out that int64 shift is quite slow... This patch changes the code from: (FLAC__int32)(xmm.m128i_i64[0] >> lp_quantization) into: _mm_cvtsi128_si32(_mm_srli_epi64(xmm, lp_quantization)); Encoding of 24-bit .wav files with 32-bit FLAC became noticeably faster. The new code works only if quantization <= 32, but its max value is 15 so the code always work. (max_shiftlimit == (1

Sadly the latest optimization broke completely everything. The asm code isn't gas compliant. the libFLAC linker script has a typo, disabling the asm optimization and/or altivec won't let a correct build anyway. Instant fixes for the asm stuff: sed -i -e"s:;:\#:" on the lpc_asm.s to load address instead of addis+ori you could use lis and la and PLEASE use the @l(register)

hi, according to the FAQ flac supports multichannel formats. i had no luck with 1.1.4 though ( "Untitled.aif: ERROR: unsupported number channels 8 for AIFF" ), i guess that feature was added in 1.2? unfortunately, the binary for 1.2 does not run on OS X 10.4 (says libiconv is too old). i removed libiconv and reinstalled that from source, but then flac 1.2.1 just prints

This lpc_restore_order was partially inspired by Miroslav's affd, though my (not very great) ARM asm version resembled this, as well. The other two reduce CPU array indexing overhead in loops a little. Additionally, a request for help: My not very optimized lpc_restore_signal is at the below URL, I couldn't get the ldm* instructions to work as advertised, even though I've talked

Hello, I just tried to compile libFLAC (using Borland C++ Builder 6 on Windows). The compilers yells at me on line 233 of libFLAC/lpc.c *(residual++) = *(data++) - (sum >> lp_quantization); --> data is const and cannot be modified Funny thing is, if data is declared: const FLAC__int32 *data instead of const FLAC__int32 data[] everything is ok. Is this a bug in my compiler, or

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

I've had this a long time but haven't submitted it yet. I've tried to mirror the ia32 setup, so there should be a new subdirectory src/libFLAC/ppc . The first two attachments go there. The third is a context diff for src/libFLAC/Makefile.am . I have some more modified files, which I figured I'd submit after the above are checked in and working for somebody other than me. If you

The #endifs are mismatched, and my builds were failing because lpc_restore_signal* weren't getting declared. I've also commented the endifs to make them easier to match. Also, is there any reason #ifdefs for FLAC__HAS_NASM and FLAC__CPU_IA32 are separate and nested the way they are and not combined like this?: #if defined(FLAC__CPU_IA32) && defined(FLAC__HAS_NASM) I'm not
