similar to: AW: Determining the duration of an ogg vorbis file

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

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 guys, Could I get an insight on this can the OggVorbis cope with changing SampleRate mid stream ?

Monty, Thanks for writing up your thoughts on the mux design (ogg/doc/ogg-multiplex.html in cvs) Now that there's something to argue with, I'd like to comment. To recap, the documented proposal is that we make two categories of streams within the OggFile multiplexing library. Pages are sorted chronologically by the timestamp equivalent of their granulepos fields. Normal data like

No. it's in general impossible to calculate the granulepos that corresponds to a

Thanks for your reply. I am using JSpeex so it is not possible to use the libs you mention. I looked a little at the source in http://jspeex.sourceforge.net but cant see where the length can be stored. Unfortunately, that project does not seem to be maintained - no replies to queries posted on the forums. Does anyone know how to store the length of a JSpeex clip in the header? thanks, Anil ---

I've been looking over Benjamin Schwartz's Skeleton A-mod proposal. I've been pretty busy with other projects over the past few months, so haven't had a chance to look at Ogg indexing until now... In general, I think Benjamin's ideas are sound, they're improvements, and I'm open to being convinced to take them in the next index version. We may as well get the index

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 Jean-Marc and others, I put Speex support in Sweep (a sound editor) yesterday, and had some fun with it :) I'd like to get some feedback before releasing it publically. I'm not really used to speech codecs (I work more with music) but I've been quite impressed at the file size and quality (especially when you hear what I did with some of the sample files ;) I didn't have any

Cool. j^ reported that some of the tools in the Annodex SVN like mod_annodex, anxrip, oggz-merge, oggz-rip, etc will need to be modified. I do not have SVN access to edit these, so can one of you guys do it? With j's consent, I'll edit

I am looking at writing a program using php that after X number of days (eg 60 days) a speex file is created that has all the speex file in a set folder with a bit of text to speech between the file for id reasons the speex file in the folder are deleted once done based on what I have read (corrent me if Im wrong): I need to convert the speex files to wav files (executable program), then I can
