The second, not choosing verbatim frames over fixed/lpc frames is almost certainly a direct result of the first problem. The fix was changing one local variable from FLAC_uint32 to

There's an entry in the changelog: "Improved decoding efficiency of all bit depths but especially so for 24 bits (lvqcl)" A couple of comments: 1) The patch that improves encoding for all depths was proposed by Miroslav Lichvar <http://git.xiph.org/?p=flac.git;a=commit;h=4eab6313cd2198b5647d925bdb3847590505fa21> 2) "Performance checks" graph posted by Martijn van

As far as I know, that is not limited to 32-bit in the format itself, only in the implementation. However, there are two residual coding methods now: rice and rice2. rice2 was added

I think the problem is that because bogus headers might pop up in the stream of which the CRC checks out, the whole frame is decoded to validate that a frame is correct. The bogus header

Hi, This patch improves compression a very tiny bit on average, but up to 0.1 percentage point for classical music. I haven't found any tracks that show worsening compression with this patch. -------------- next part -------------- A non-text attachment was scrubbed...

I reran my tests, it took a little longer because I couldn't believe the results I got.

Hi all, The past few weeks I've been busy comparing lossless audio codecs to update the comparison.html page on the FLAC website (and because I wrote a comparison for Hydrogenaudio in the past) and its ready now. Because the patch is pretty large, I've placed it here: http://www.icer.nl/misc_stuff/update-comparison-and-fix-IE-news.patch.zip The reason to do this is because the

Hi all, I was doing some checks in preparation of updating the comparison on the FLAC page this summer and I thought the results might be interesting for people on the dev list as well. Because the mentioned comparison runs a few codecs through wine I wanted to check whether wine gives a performance hit. However, the first results confused me, so I added a few other compiles. However, it

I can confirm git head builds and passes /make fullcheck/ (skipping the noise part of test_streams.sh) on - armv6-linux (Raspbian), GCC 4.6 & GCC 4.8 - i686-pc-mingw32, GCC 4.8.1 - MSVC 2005 Express 32-bit (make fullcheck with MinGW) - MSVC 2013 Express 32-bit (make fullcheck with MinGW) Furthermore, I've also ran the test_streams.sh of FLAC 1.2.1 with FLAC 1.2.1 as encoder and git as

Hi all, I thought it was a good idea to get an overview of the developments since the release of 1.3.0, so here are a few graphs. The first was compiled with GCC 4.8, the second was compiled with MSVC 2013. Both were tested on a Kubuntu 14.04 machine, with an Intel Core 2 Duo T9600 (SSE support up to "version" 4.1), the MSVC compiles were run through wine, as I don't think

I'm quite sure that's the culprit. Add -O3 to your

The FLAC 1.1.2 release candidate is now available at http://prdownloads.sourceforge.net/flac/flac-1.1.2-beta.tar.gz?download Only the source tarball is available. I am putting out the beta first so that package maintainers and others can smoke test the build/install/check process before the official one goes out, since we've had problems before. Everyone that can, please download and try:

Hello, This is a patch to allow building of the project using MSYS, MinGW, and MinGW-w64 with the following invocation: make -f Makefile.lite libFLAC libFLAC++ flac metaflac test_libs_common test_libFLAC test_libFLAC++ test_grabbag test_seeking test_streams utils examples This patch addresses eight points: 1. `uname -p` in MSYS returns "unknown" so we must use `gcc -dumpmachine`

My decoder now works correctly for files encoded with the default settings. Are

Hi all, For testing a few mingw-builds I tried to use ./configure --disable-thorough-testing (because testing in a virtual machine through mingw isn't really fast) but it turned out this setting doesn't do anything. It turns out these configuration options aren't passed to the test scripts at all. I do not fully understand how Makefiles or environment variables work, but my
