...// try to extract a page ogg_stream_pageout(os, og) ogg_stream_pageout() always seems to return a valid ogg page - however, it does "return" the page, but it does not "extract" the page from the stream - if i call ogg_stream_pageout() more then once, i always get the same ogg_page. replacing ogg_stream_pageout() with ogg_stream_flush() got the same results. what is the proper way of creating an ogg_page? Thank you very much, Chris

Hi, i just wonder if there's a cheap way of getting the number of oggVorbis pcm frames in an ogg_page, without actually decoding it? Can i use the granulepos of the page, substract the granulepos of the previous page? is this always guaranteed to work? thanks, Chris

It seems to me that running ogg_sync_pageout doesn't automatically advance the page. This is good if you haven't worked with the given page, makes coding somewhat easier. However, when does a page advance. Is it after a call to ogg_stream_pagein? On a side note, I need to do seeking on top of libvorbis, I'd love to use vorbisfile but sadly I can't. Is there a reasonable way to

Perhaps someone could have a look at my source code and tell me what? After encoded the frame, the body_length attribute of the ogg_page op from encode has some reasonable value. But sizeof(*op->body) returns 1... The output I get is a big black screen... Any suggestions?

...initialize your b before calling the function though (like oggpack_buffer * b = NULL;), but you wouldn't have to reveal the structure itself (enabling the definition of such a struct). [I see, I can't make a short speech...] While we're at it: I found that the function extern int ogg_page_getbuffer(ogg_page *og, unsigned char **buffer); is declared in ogg.h but not defined. (I am glad however to find such a function; earlier it did not exist. This should be possible for packets too for reading and writing because it's faster if you don't write single bits.)

You can use a function like this (copied from oggz-chop.c, where it similarly cuts the end of a file): static void _ogg_page_set_eos (const ogg_page * og) { if (og == NULL) return; og->header[5] |= 0x04; ogg_page_checksum_set (og); } > Furthermore, since API claims that the 1-1 correspondance with YUV encoded > buffer and ogg packet might not remain in the futur, I believe such function > may be usef...

Greetings, How does the ogg_page_bos function work? I call this function directly after calling ogg_sync_pageout. It works. Then I place a guard around it until the start of a new stream (chain mode). If this is the start of a new stream, should it return zero after the next call. I looked in ogg_page structure to see if there is...

I'm adding some final features to my CD Ripper and Encoder before the full, version 1 release. As part of that release, the program will offer the ability to play (for review purposes) both WAV and OGG files. I have both the decoder and playback code working but I have one final issue to resolve: finding the play time for the Vorbis bitstream that is being played back. I used the

My first guess about the problem would be that the programs want to process the stuff in a different order, e.g. mplayer wants to output some sound before anymore video and encoder_example wants to receive some video before anymore sound. This could easily depend on the order of stuff in the file mplayer is reading. I guess something similar could happen for opening the pipes as well. The
