hi all I found that in the revision 10730 of the libogg2 library it is impossible to do bitpacking. this is due to the implementation of the (at least) two functions oggpack_writeinit() and oggpack_readinit(). they both take an (oggpack_buffer *) as an argument and immediately erase all it's contents: void oggpack_readinit(oggpack_buffer *b,ogg_reference *r){ memset(b,0,sizeof(*b)); b->tail=b->head=r; b->count=0; b->headptr=b->head->buffer->data+b->head->begin;...

Hi we run a util at work called 'bounds checker' and it came up with this little beauty: void oggpack_readinit(oggpack_buffer *b,unsigned char *buf,int bytes){ memset(b,0,sizeof(oggpack_buffer)); b->buffer=b->ptr=buf; b->storage=bytes; } Stack memory overrun: Copying 20 bytes to opb; Starting offset 0, destination size 4 bytes. This is in RC1 code base. Any ideas? fixes? I'll try and...

...t decode something properly, I got nothing but noise (being linked with native vorbis lib it decodes perfectly). I started to walk inside Ogg sources as well as its Tremor version, and found that they use quite different version of data structures, oggpack_buffer for instance. For another example, oggpack_readinit uses argument of `struct ogg_reference' type, which lacks in upstream library at all. So I guess that the functions despite from their identical name do not do identical things. So the problem is: I need to use in my application the code from three libraries: Ogg, Theora and Tremor. Theora rel...
