...cribed in the above document. I'm able to write/read matrices of 4x4 and 9x9 and encode->decode first and second order just fine, but writing larger matrices causes what seems to be some sort of packet corruption. The OpusHead packet is never found, but in it's place we have a packet at b_o_s=256 (which is where OpusHead usually lives), but the byte size is reported to be 0 and e_o_s=0 as well. (This is generated by parsing the packets via ogg's *ogg_stream_packetout* function. It appears a matrix larger than 7x16 causes this issue. (The matrix values are all signed short vals, so &...

...this connection some questions: A) Are codebooks in file headers depend only on Vorbis version and encoding parameters and don't depend on the particular source file? B) Are the following steps enough to do merging?: - unset e_o_s flags in the last packet of the first file; - unset b_o_s flags in the first packet of the second file; - write additionally to the first file data data from the second file, which located after headers of the second file, at the same time changing granuleposes and packetnos for packets from the second file; Thanks. Vitaly. --- >8 --...

...are stored as little-endian. The speex_string field must contain the ``Speex `` (with 3 training spaces), which identifies the bit-stream. The next field, speex_version contains the version of Speex that encoded the file. For now, refer to speex_header.[ch] for more info. The beginning of stream (b_o_s) flag is set to 1 for the header. The header packet has packetno=0 and granulepos=0. The second packet contains a user-comment string, without terminating null. The content/format of the comment string is not defined. This packet has packetno=1 and granulepos=0. The third and subsequant packets e...

...ork? 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 a member named b_o_s, but I did not see anything. What is being used to determine BOS when the ogg_page_bos function is called? THKS Radmin

...I was wondering what oggz_get_bos and oggz_get_eos are supposed to do, specifically are they meant to be used in oggz_read mode? The documentation says "Determine if a given logical bitstream is at [bos/eos]". However if get_bos is given a specific serialno it returns that stream's b_o_s flag which, in read mode, is set on initialisation. The serialno=-1 (for all streams) instead checks delivered_non_b_o_s. Are these functions really intended for write mode? Thanks imalone

1.) after initializing a ogg_stream_state may I just keep calling ogg_stream_packetin with valid ogg_packet's until no more ogg_packets needs to be added? Or do I need to call ogg_stream_pageout after every ogg_stream_packetin? Iaw may I delay calling ogg_stream_pageout until there are no more packets to be added? 2.) I assume I have call ogg_stream_pageout until no more pages can be
