Hi all, I tend to compile my code with all GCC warnings turned on. However, when I do this : vorbis_comment_add_tag(&vdata->vc,"ENCODER","libsndfile"); I get the following warning messages: warning: passing argument 2 of 'vorbis_comment_add_tag' discards qualifiers from pointer target type warning: passing argument 3 of

Dear Vorbis devs, I'm Robert Kausch, author of fre:ac - free audio converter. Please consider using _ogg_malloc/_ogg_free in place of alloca in vorbis_comment_add_tag. alloca will cause undefined behaviour/crashing when it causes a stack overflow which can easily happen when adding cover art in a METADATA_BLOCK_PICTURE comment. I had a user trying to convert a FLAC file with a 2 MB

I was looking over the comment manipulations routines defined in vorbis/codec.h and info.c and I noticed that each "char *" could/should really be defined as "const char*". Is it expected that this will change or was it defined like this for reason? void vorbis_comment_add(vorbis_comment *vc, char *comment); void vorbis_comment_add_tag(vorbis_comment *vc,

I just committed a bunch of work on the comment interfaces in libvorbis. Importantly, there is now a way to deal with non-0-terminated strings being returned in the comment structure. THe vorbis_comment struct has an additional member - int *comment_lengths. Unless you're editing the struct directly (i.e. not using vorbis_comment_add(), etc.), no changes will be needed to applications (but

Hi, after banging my head against the wall for quite a while I finally found what crashes my code: Because I'm working with Codewarrior 8 on OS X I had to compile the ogg / vorbis libs with CW. To do so I used the CW projects for OS 9 and modified them. Howerver, they don't work as expected. Everything seems to be fine, encoding & decoding works, only vorbis_comment_add_tag() crashes

I've got a bunch of flac files and need to report their length. With MP3s, you use `mp3info -x $filename` But is there a way to find out the length (minutes:seconds or just seconds) of a flac audio file, without converting it to WAV first?

Hi, I haven't seen any information about Lyrics in the documentation and mail archives, so I guess the answer... but may be I've missed something... Does flac support lyrics? Regards, J?r?me

Both MPEG-4 File Format (mp4) and Matroska (mkv) have an interesting format for lyrics and subtitles. Since these container formats can contain multiple contain streams, lyrics or subtitles are just another "stream" interleaved with the rest of the data. They are synchronized by having timestamps like any other stream. The payload is just text data. If you don't care about

hi, this is way off topic, but maybe someone can help... i'm looking for a script or prog that gives me info on a mp3-file, like what mpg123 shows when starting up plus some tech details like size, time, frequency etc. i've tried perl-MP3-Info, but it doesn't know about album, title, artist etc. i want to use it for fetching as much info as possible from a file into a database. any

Hi, I've heard somewhere that it is possible to store inside .ogg files text streams and thus it should be possible to store lyrics for the sond directly in the file. Is it true? Could anybody point me towards some code how to do it (Python preferable, but not required)? Is there any documentation for text streams in .ogg files? Thanks for any reply, Mat?j -- GPG Finger: 89EF 4BC6 288A

Hi Folks, What is the proper way to embed text stream into the Ogg stream? I need to have text information (lyrics as example) recorded together with the audio. Is there a standard mechanism for that? What is the right way to do it?

One of the great things about Ogg (in addition to fantastic sound quality) is the ability to insert anything into a file tag, including lyrics. What would be sweet would be a visualization plug-in which would read the "lyrics" tag and display this text in a resizable window. Does anyone have experience programming winamp plug-ins?

I've come full circle on the Ogg text stream format, back to arbitrary associated xml streams. What's changed? Mostly rolling the requirements around in my head, and weighting them differently. I think we've dealt with the complexity issue; this functionality can be optional for "dumb" audio players, and possibly also for dumb video players, though there it's a smaller

Ok, so I finally got the id3/mp3 end of things worked out for the next release of QTagger and I'm back to implementing tag reading for Ogg Vorbis. I've got some code that will read tags, but I haven't been able to figure out how to write them. Here's the code that I'm using. It's a fine C/C++ mix. The code will eventually be in a C++ app, so I don't mind

To be honest, I just added Theora because I needed a simple way to multiplex streams. Also, it'd

this is a little off-topic, but i want to get a sense of "best practices" for tagging flac files. i want to archive my entire cd collection as flac files (onto a few of those new western digital 120GB drives). as part of encoding the flac files, i'd like to add 1. id3v2 tags (preferably automatically gotten from freedb) 2. timed lyrics a la lyrics3 v2 (is there a freedb-like

Hi, [ Was away the last few days, so this partly overlaps on things that that have been mentioned in this thread. Since the consensus seems that Vorbis comment encoding is the way to go, it's a bit moot, but here it is anyway ] Following up on the possibility to tag various images as different types of album art, I thought of adding that tagging information in a Skeleton stream.
