similar to: packets and OGG pages

Thanks for your replys. >packets don't always begin at the >start of a page OK, since I only want to read / write the Vorbis comments, I can limit it to the Vorbis header packets. http://xiph.org/vorbis/doc/Vorbis_I_spec.html stats that the comment header always begins on the second ogg page. Since the length of the precedent identification header is fixed, this even is a fixed offset

>Searching for 'vorbis' to find the packet boundary is wrong however. >The lacing values in the Ogg page header tells you exactly where the >division is. OK, so given the fact that a page can also contain multiple packets this means that the lacing values of one page could be like the following example: 255 255 189 (something less than 255, indicating that a new packet starts

Hello, I'm still working on the native .NET ogg tagging library. It already works well for non-multiplexed ogg vorbis, ogg flac and native flac files. Concerning multiplexed files, I've got two short questions: 1) Is it valid to insert an "empty" page into the stream which simply contains the binary value 0 for the page_segments counter, and which therefore contains no segment

OK, I've found the answer for one of my previous question myself in the meantime. The comment header can of course be split over more than 1 ogg page since the comment header can be greater than 64K. It also seems to be possible that both comment AND setup headers are placed on a single ogg page only (as stated in the Voribs specs). Due to the fact that the first audio packet also begins on

Hi, I think we can start by defining an official field name at www.xiph.org/vorbis/doc/v-comment.html which is used as a file system link to an existing image file. I suggest the field name to be "PICTURE". What is ogg MNG? Is it a container format for PNG files which should be embedded in OGG files? If I understand correctly, the picture would be placed in a different logical stream

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?

Hello, I've mainly finished the native ogg Vorbis tagging .NET library. It already works well for reading and writing the vorbis comments for the files I tested. The library only rewrites the entire file if it has to, and adds 2 K padding in this case so that further changes of the comments won't make it nescessary to rewrite the whole file again. I found out foobar2000 also does it this

>That would be great! We always need help improving our documentation. OK. I'm going to start writing this lib now, and as soon as it works well I'm going to write specs about how to tag vorbis files. I'll let you know then. Maybe I have to ask you some further questions during development. Let's see. Thank you so far, Mathias

Beside that, multiplexed logical streams suffer from pretty bad software / hardware support, isn't it? It's better to display album art as text if the player doesn't recognize the base64 album art, than being unable to even play the file. ----- Urspr?ngliche Mail ---- Von: Kyungjun Lee <kjoonlee at gmail.com> An: xiphmont at xiph.org CC: vorbis-dev at xiph.org Gesendet:

Hi, The documentation at http://www.xiph.org/ogg/vorbis/doc/oggstream.html tates that "Each chained logical bitstream must have a unique serial number within the scope of the physical bitstream" Doesn't this mean that the sequential multiplexed streams have same serial number? I am confused looking at the following code segment in vorbisfile.c

Hello, I'd like to ask about the possibility of embedding pictures like an album cover artwork into a vorbis comment header. Since the data in a comment string after the separating "=" has a defined length, this could theoretically also be binary picture data. For example "PICTURE=[...any binary data...]" It only would be a problem for existing software which isn't

hello, I have a problem with an unsuitable font in the windows menus/dialogs with the above versions of wine (dont think this depends much on the versions, though. Have not tried other versions so far.) when using debian sarge. The font seems to look a bit ugly, usually destroys partly the menu/dialog structures, and, most important, has no German umlaut's (the diphtongs ae, oe, ue and

Howdy, yeah, I've finally collected all your feedback on my I-D on the Ogg encapsulation format, many thanks to all of you! Below, I've listed the changes that I have made to the previous version and the attachment contains the complete new I-D. If there are any more change requests, please send me wording proposals as it's easier to include. :) Monty, in case you are doing any

Hi all, I've got a question on regarding how to find out the duration of an ogg vorbis file. Sorry if it should already be mentioned somewhere in the docs, but I couldn't find out how to do it the best way. So, I can read the [bitrate_nominal] field from the identification header (if it is set), find out the size of the audio data (by subtracting the size of the three headers from the
