So I recently encoded my entire CD collection (over 7000 songs) to flac and I have found that 18 of them have a strange problem.  The files are corrupted in some way.. They will stop playing abruptly in the middle of the song.  I've attached a listing of the metadata and you'll see what I mean.  You can see that the seek points toward the end have a bunch of zeros and I'm not sure

Hi I have downloaded a FLAC file somewhere and when trying to decode it to WAV it gives the error message: ERROR, MD5 signature mismatch So my question is now: are FLAC files that give the error message above still decodable to WAV (and how can you do this, because flac.exe doesn't want to decode the file), even if there is a MD5 signature mismatch, or is this not possible at all? thx

As far as I can tell I've found a serious bug in the command line flac encoder :( I have created many hundreds of flac files and I was very annoyed to discover that the XMMS flac plug-in had intolerably long seek times, but since that had been mentioned on this list a bunch of times without anyone actually investigating, I thought I had better actually find the BUG which causes this. 1. I

Are you sure it's not your compiler? That's the first thing I would check. I know that RedHat is famous for including broken pre-releases of GCC in their distributions since 7.0. I'd try recompiling with GCC 3 or GCC 2.95 (available as "kgcc"). -- Asheesh. On Sat, 16 Mar 2002, Nick Lamb wrote: > As far as I can tell I've found a serious bug in the command line

Hello, I work at SmarctJog.com, we have here some patches on IceCast for performance and reliability, these are mostly client/connection/source cleanups (a slave merge is underway, and some more good stuff (c)), but we'd like this to be merged in before the list gets any longer. Please find attached a list of our patches with a short desc: This one is actually not from us/me, it was found

...n something (Not audio data). Looking at this, I used a Windows native installation to check about this and confirmed that the flac.exe in Windows is also creating a file that differs a little than the flac ELF. At first glance I compared the metadata and it seemed that metaflac returned different stream_offsets from the seektable, comparing the same music file created with flac-win and flac-lin. Then I removed entirely both their tags & padding, but they still are different. Is this normal? Music data is absolutely untouched, however, can this be an architecture difference between the compilers that...

When I was trying to find yesterday's xmms-plugin bug, i have noticed that seeking in stream without seek-table isn't very good. With attached patch it is much better. -- Miroslav Lichvar -------------- next part -------------- --- src/libFLAC/seekable_stream_decoder.c.orig 2003-02-26 19:41:51.000000000 +0100 +++ src/libFLAC/seekable_stream_decoder.c 2003-07-09 23:49:35.000000000 +0200

Ok, the patch from 2003 about improving seeking still didn't make it to CVS, so here is another try. I made some benchmarking with the test_seeking utility from flac sources to show how bad the current seeking is, especially without seektable. Track used for the experiment had about 50 minutes. In the following table is average number of seeks and number of decoded frames required for one

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

Hello, I'm using flac to compress s signal data during capture. The sample rate is almost a thousands time higher compared to audio (40 MHz), resulting in a lot of data very quickly. I'm using the C API in my capturing application (mostly copy&paste directly from the example) and it works so far, but unfortunately for longer captures there is no seeking information. How can I tell
