similar to: Serious bug in FLAC

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

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

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

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

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

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

Erik, My working view has this as the last commit: commit 19e3918d4e35f4ab99e7fcc58c169025c576dd16 Author: David Schleef <ds at schleef.org> Date:?? Thu Aug 25 18:40:29 2011 -0700 ??? Fix md5 structure clearing in previous commit Using this, test_metaflac.sh runs cleanly with my cuesheet.c change. I set up another view using HEAD at git.xiph.org, and in this other view

If I use flac to encode with the --replay-gain option, I get a warning about the --no-padding option... "NOTE: --replay-gain may leave a small PADDING block even with --no-padding" ...even though I'm not using --no-padding. And the file does end up with a small padding block, so changing tags is slow. I'd fixed this bug in my own copy of flac 1.1.4, but forgot to submit the

Hi everyone, I was fiddling with FLAC executable on Linux and also making FLAC files with foobar2000 under WINE. I was using the same exact options for both linux native executable and flac.exe through foobar2000. But I have noticed something: The FLAC files themselves created from flac.exe and flac(ELF) are not bit identical. They differ in something (Not audio data). Looking at this, I used a

Hi! I've been using a little C++ program I've written to encode flac files. The program does this in the usual way (I think), by inheriting a class from FLAC::Encoder::File, and passing it chunks of raw samples through process_interleaved()... Anyway, the program works beautifully, and I've now decided to try and add some metadata to the encoded flacs. Eventually, there will be vorbis

I first thought that it would be much better to create a single seek standard for FLAC. Then, I thought, why couldn't someone just create the optional SEEKTABLE data after an initial encode, if they need this data? Since the checksums are a part of the FLAC format (unlike Shorten), and these checksums are on the data stream, not the metadata, so any additional metadata shouldn't matter or
