search for: seektables

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've checked in code that supports a new metadata block called SEEKTABLE. Basically, it is an optional, arbitrarily-long list of seek points, by sample number and stream offset. I also added command-line options to flac so you can specify seek points by specific sample number and/or a specific number of evenly-spaced seek points. The table cost about 18 bytes per seek point. This seems to

I'm attempting to decode part of a largefile flac whose seektable is broken or missing and the file is shorter then it's supposed to be, when I use 1.1.2 it decodes fine, when I use 1.1.3 it fails flac --decode --skip=719:58.0 --until=1024:58.0 -o \/home\/sbh\/work\/hs\/out.wav \/mnt\/ss\/sdb\/Sound\/Recording\/2006\-11\-29\/in.flac out.wav: ERROR seeking while skipping bytes

Please excuse me, I haven't yet dug into the code too far. What I'd like to do: I'm using ecasound to record for 24 hour periods, which pipes the output directly to flac. I would like to be able to decode sections of this (using until/skip) during recording/encoding. I understand currently that flac can't do this, unless I pipe into dd to skip after decoding (which would be an

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

...stalled but did not configure OGG support will have a high (but not 100%) chance of creating flac files with no seektable, and no MD5 checksum, and various other things wrong. I recommend that in addition to fixing the original bug it is now too late to avoid tweaking libFLAC so that ignores bogus seektables, and probably someone needs to write a tool that either removes the seektable altogether or corrects all the file metadata by scanning the file <sigh> Hopefully the people who replied so dismissively to my original bug report will turn out to be useful and will help make these changes. Other...

The attached patch adds the missing FLAC__metadata_object_seektable_*() functions from FLAC's metadata object methods (FLAC/metadata.h) to FLAC++'s SeekTable class. Of the 11 functions in the C API, only 4 are currently in the C++ API, this patch adds the missing 7. If this patch is ok, VorbisComment will be next. A quick look tells me only 5 out of 13

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

I am trying to encode a stream to FLAC and want the encoder to create a SEEKTABLE but I cannot get it to work as the table always contains only place holder points. All other aspects of the produced FLAC file seem OK. In order to eliminate anything in our system I modified the encoder sample code from the website and it behaves the same which make me think I'm missing something. I

I have read FLAC's "--help", the man-page, and the HTML documentaion, but there are a few things that I don't understand. 1. I'll start with the thing I'm most confused about. The --best option is synonymous with -l 12 -b 4608 -m -e -r 6. Why is that? Is not -l 32 better that l- 12? And you can have -r 0,8 without using --lax, and -r 0,16 with --lax. 2. The --lax option

I have noticed flac -S- isn't working correctly, '-' isn't handled in parse_option() nor in convert_to_seek_table_template(). It makes SEEKTABLE with one seek point. Similar options -V-, -e-, -p-, ... are not allowed since 1.0.4, I think best would be drop -S- from documentation too and use --no-seektable option only. -- Miroslav Lichvar

Hi all, A few (possibly dumb) questions about decoding.. 1. Is it possible to know the total size of FLAC metadata blocks in advance? Do I really need to parse all metadata blocks until I see the METADATA_BLOCK_HEADER with last-metadata-block == 1? 2. Is there a generally accepted best-practice for seeking if there is no seektable present in the file? The format states *"It is possible to

Hi guys, Thanks Matt for your prompt response about the C++ problem, its working great now! Again for my "virtual cdplayer", I am wondering if its possible to stop decoding within a large file, at the end of an exact sample? ie. I wish to play a song in the middle of a flac'd cd. Using the file decoder, I can seek to the start of the track(index 01 of the cds TOC), but I then want

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

my apologies for not doing this before Miroslav... I will definitely integrate it this time.
