Hi all, I'm mixing logical streams at the page level. One stream has vorbis data, the other has my own data. Do I need two ogg_sync_states or just one?

...is pages (only all those theora pages) you don't get any new packets and so run out of data. Thanks for the hint related to the liboggplay API. But did you read it's source code? Please tell me, why there you can't find any of these functions or states we are talking about. There is no ogg_sync_state, no ogg_stream_state, no pagein, no pageout, no packeout, nothing at all besides vorbis/theora decode calls. So why the developer is working with his own functions only? I think it's because most of the ogg sync/stream handling functions are crap or at least not usable in efficient real world...

...theora streams are possible (or you get thos collissions). I think, an ideal solution are two "pointers" in seperate threads reading independently the physical source stream and grab their pages (and prepare/decode them) but ignore the other ones and don't need to wait. So I need two ogg_sync_states or something like that? It must work in a way without all these ogg states because in the case of Direct Show the filters (ogg demuxer, vorbis decoder, theora decoder) are completely independent from propritary ogg states (they are not visible for others outside a COM object). It would be great...

I guess I'm missing something since the following minimized test case is failing: >>> #include "ogg/ogg.h" main() { ogg_sync_state the_ogg_sync_state; ogg_sync_init(&the_ogg_sync_state); ogg_sync_destroy( &the_ogg_sync_state ); } >>> $ gcc -g -logg test.c $ ./a.out *** glibc detected *** ./a.out: munmap_chunk(): invalid pointer: 0x00007fffe0562330 *** ======= Backtrace: ========= /lib/libc....

Dear members, since two weeks I am stuck, trying to demux a physical ogg stream (theora 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) -...
