WebP (imagepart of VP9) is better then JPG AVIF (imagepart of VPX/AV1) is better then HEIF please support in OPUS file for album arts more then JPG and PNG... WebP and AVIF are free imageformats can store multiple images thats good for the problem with METADATA_BLOCK_PICTURE only can store one file. i try to push some devs of player and converter to support this too. wbr from berlin

Hi everybody, I have a question about the following part of the METADATA_BLOCK_PICTURE specification. The components: Width, Height, Color Depth, and Colors Used don't provide an "unknown" value and seem to assume that the program encoding the METADATA_BLOCK will be aware of these components of the file. As these fields seem to just provide "extra" informatio...

Does anyone know of any music players that support the METADATA_BLOCK_PICTURE field in vorbis comments for Ogg Vorbis files? I've added support for this in my little CD ripper app and I'd like to test against a real player. Thanks. -- Jason Voegele We were so poor that we thought new clothes meant someone had died.

...ime. I am writing a program that reads and writes all existent Tags types. It lacks only to end the edition (rewriting) of "Native" Flac and Matroska. Both cases for the same problem: the separation of Tags and Picture in different blocks. In Flac I resolved it, but now I have to add METADATA_BLOCK_PICTURE. Reading Vorbis Comments of different file types as binary I found they were not compatible. I don't use in any case the libraries provided. All code is own Visual C #. For that reason I have these problems. In Vorbis Comments case is maybe already solved in the libraries provided, but I ha...

You said "With the exception of where to put a picture file, VorbisComments in a Vorbis stream are the same as VorbisComments in a FLAC stream." In METADATA_BLOCK_PICTURE case they would not be the same. Up to now we could exchange the complete block of VorbisComments. But with the addiction of METADATA_BLOCK_PICTURE doesn't happen this way. In Ogg files the METADATA_BLOCK_PICTURE data are split in numerous pieces, each one of them with a Oggs header (44 up to...

This was just reported as crashing an application. I know that is an invalid block size, but just rejecting it would seem better. I haven't got metaflac to crash yet, although I did hang up my terminal on one attempt. --ian

Hello, I have problems with encoding FLAC-Files with embedded pictures. Currently i use opus-tools 0.1.7 with libopus 1.1-rc2. After encoding opusinfo shows WARNING: Unknown picture type in METADATA_BLOCK_PICTURE comment 12 (stream 1): 1768776039 WARNING: Invalid mime type length in METADATA_BLOCK_PICTURE comment 12 (stream 1): 1697607790 bytes when 5562 are available When i play the files with opusdec it shows the picture base64 encoded, which is not very useful, but it scrolls the useful information out...

Ogg files can have multiple COVERART or METADATA_BLOCK_PICTURE tags without a problem, though. METADATA_BLOCK_PICTURE is part of the FLAC spec, not OGG (and definitely not Opus), and you can have as many METADATA_BLOCK_PICTURE blocks as you want, so even if each can only store a single picture I'm very unclear about what the problem is? Opus isn't rela...

Hello, I am new to using opus but so far I really am loving it. At 16kbps spoken content sounds fabulous. I am using opusenc on 64-bit linux - mostly with flac input. The one thing I can't figure out how to do is add album art. I tried passing the vorbis way of adding a metadata_block_picture comment field to opusenc but it complained about the length. I can't seem to find any application like vorbiscomment for opus that would let me do it after the encode. Does such a utility exist? I really need it to be CLI and work in linux, this is being scripted for an audio hosting server....

Hello to the people reading this list! I am developing tagging support for ogg vorbis in Nero products and we are currently thinking of supporting cover art in ogg files. What is the current state of proposal for cover art in ogg files? Is this http://wiki.xiph.org/index.php/VorbisComment#Cover_art still the latest information?

...rbis 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 embedded cover art that caused a crash in vorbis_comment_add_tag. Thanks and best regards, Robert PS @ list moderator: I sent message before I joined the list a few days ago, but it was ignored. The mail should still be in the mod...

This is a minor point, but FLAC users can already do this using METADATA_BLOCK_PICTURE (which allows binary images).
