Libogg contains a set of functions used in the encoding process.
All the libogg specific functions are declared in "ogg/ogg.h".
When encoding, the encoding engine will output raw packets which must be placed into an Ogg bitstream.
Raw packets are inserted into the stream, and an ogg_page is output when enough packets have been written to create a full page. The pages output are pointers to buffered packet segments, and can then be written out and saved as an ogg stream.
There are a couple of basic steps:
function | purpose | |
ogg_stream_packetin | Submits a raw packet to the streaming layer, so that it can be formed into a page. | |
ogg_stream_iovecin | iovec version of ogg_stream_packetin() above. | |
ogg_stream_pageout | Outputs a completed page if the stream contains enough packets to form a full page. | |
ogg_stream_pageout_fill | Similar to ogg_stream_pageout(), but specifies a page spill threshold in bytes. | |
ogg_stream_flush | Forces any remaining packets in the stream to be returned as a page of any size. | |
ogg_stream_flush_fill | Similar to ogg_stream_flush(), but specifies a page spill threshold in bytes. |
