...PI to find out which ones are the start of pages? (Other than trying to decode from successive 'OggS' markers and noting when the resulting page changes.) Is this what ogg_sync_page_seek is for? I can't quite work out from the documentation what it does. http://xiph.org/ogg/doc/libogg/ogg_sync_pageseek.html Does the sequence go, get a page, find a nearby 'OggS', put data from that point into a sync_state and ask pageseek whether we're in the right place? -- imalone

...A more general way to choose an info struct 2. vorbisfile: Write capability. 3. ogg_page: A way to compute page length. In order to compute the page length, I've been adding header_len and body_len - which is currently correct - but it's not part of the spec as far as I can tell. ogg_sync_pageseek would tell me the page length, but if I should use that, then who needs ogg_sync_pageout? 4. analysis/synthesis: a. I wouldn't mind if vorbis didn't use separated channel buffers, but since I don't understand the compression details, they might be really important. b. I...

This is obviously because libvorbis comes before vorbisfile on the command line ;). It really seems like we should be doing "-L../lib -lvorbis" instead of ../lib/libvorbis.a though, and that would fix the pr...

...lbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I need more specific information about the seek algorithm. As far as I know, I could use ogg_sync_pageseek() function to find the next page; if it returns 0, that means I need to read more data; if it returns n, that means the page was synced at the current location with a page length of n bytes, so the location is where the ?Oggs? is, am I right? And if it returns -n, does it mean I already skipped n b...

Any time code is stuck in a loop calling ogg_sync_pageseek() or ogg_sync_pageout(), you'll see most of the time sunk into checksum calculation. It's the only thing in libogg that _can_ take much time. This is not likely a libogg bug, but a bug in the code calling libogg in a tight loop. Looking at the file listed in the bug, there's a page d...

Hi, I have now played around with seeking a bit. Currently I can seek into a file position in splayer and resynchronize playing (via ogg_sync_pageseek) from there. I did not take chained streams into account yet, as I'm not sure if it would make splayer far to complex for a sample application. Maybe later. Before I implement seeking to a specified time (ala libvorbisfile), can you answer me these questions: 1. Libvorbisfile does a vorbis_s...

...*,ogg_int64_t). But what do I have to do while doing the jumps to find this? This is what the code currently does just after seeking to a new place in the file: // Clear the current ogg buffers, find a new page, and fill the buffers again int result; ogg_sync_reset(&sync); while ((result = ogg_sync_pageseek(&sync, &page)) <= 0) if (result == 0) bufferData(); // Find the next theora page while ((result = ogg_sync_pageout(&sync, &page)) == 0) bufferData(); while (ogg_page_serialno(&page) != tstream.serialno) if (ogg_sync_pageout(&sync, &page) <= 0) bufferData...

I have searched the net and I have found other people who are having problems compiling libvorbis, but I have not found a solution. My problem occurs when trying to create library libvorbisfile.dll.a I get multiple undefined references like undefined reference to `ogg_sync_pageseek' I was able to compile libogg without a problem. I am using msys with ./configure and make to build the library. Are there instructions somewhere I have missed? Thanks!

...a and vorbis) and play the audio part using vorbisfile. I hope that one of you can give me a hint or point me to additional documentation. I used ogg.h and vorbisfile.h. The way so far: - initializing an ogg_sync_state - inserting data to sync_state using ogg_sync_buffer - when whole page found (ogg_sync_pageseek(&sync, &page) > 0) I initialize a ogg_stream_state and add page using ogg_stream_packetin. (in the case the first packet is vorbis - ogg_stream_packetout and check for first some bytes) - next pages with same serial number are handled equivalently: stored in ogg_stream_state using...

I need to be exposed to a way of seeking theora streams. I have repeatedly found the same question asked on a different forums but could not find an answer. I'm working on a game and started integrating video with theora, the sound works just fine with ogg/vorbis(i find it easy to seek using ov_raw_seek for audio files). Could someone please point me to some example/code of how can i seek with
