...ve now decided to try and add some metadata to the encoded flacs. Eventually, there will be vorbis comments, but right now I'm just trying to add a seektable. From some code examples I've managed to get it working using the libFLAC C API like this: FLAC__StreamMetadata *md[1]; md[0] = FLAC__metadata_object_new(FLAC__METADATA_TYPE_SEEKTABLE); // THIS LEAKS FLAC__metadata_object_seektable_template_append_spaced_points(md[0], 13, d_bytestotal / 4); FLAC__metadata_object_seektable_template_sort(md[0], true); set_metadata(md, 1); Now, I have several questions: 1. Most importantly: How can I get this...

...cation ID value in my metadata object. I am currently working around the issue by setting the value manually, but that hurts my good coding sense. (Note: I have already registered my ID.) Is there an API call to set the application metadata ID? Here's what I'm doing: myFlacMetadata = FLAC__metadata_object_new (FLAC__METADATA_TYPE_APPLICATION); FLAC__metadata_object_application_set_data (uitsFlacMetadata, myMetadata, myMetadataSize, FALSE); /* this is a BIG FAT NO NO, but I cannot for the life of me find any way in the FLAC API to set */ /* the Application block application ID, therefore I a...

...ST and TITLE from the file. A while back, I was popen()ing to metaflac, because I didn't want to mess with libFLAC. But now, it's the weekend, so I can mess around with this.

...asn’t suggesting that you run metaflac, but that you examine its source to see how it creates new FLAC files without the Vorbis comment. As far as I know, metaflac uses the standard libFLAC and creates files without the Vorbis overhead. My quick review of the source seemed to indicate that calling FLAC__metadata_object_new(FLAC__METADATA_TYPE_VORBIS_COMMENT) will create the comment, but I assumed that you could pass in NULL. I mistakenly thought that was FLAC__stream_encoder_new(). There is a comment saying that the Ogg FLAC mapping requires a VORBIS_COMMENT, but that doesn’t necessarily mean that standard FLAC also...

I changed the section where the meta data is added to the encoder to add a seek table block.

yes that is what i did. got the "requires version 7.0.0 or later, but libiconv.2.dylib provides version XYZ" (forgot which version i had before). removed libiconv, downloaded compiled and installed the new one (libiconv-1.13.1), then i just get $ flac Bus error i reinstalled flac 1.1.4, still runs fine (but doesn't support multichannel). cheers, -sciss- Am 05.08.2009 um

Correction, the flac command-line does create a 40-byte Vorbis comment by default. I just never noticed it before. I’ve been using —no-padding all these years for minimal file sizes without realizing that I could save another 40 bytes. Anyway, since metaflac can remove the Vorbis comment using the standard library, then you should be able to create a solution without modifying libFLAC. Brian
