declared in "ogg/ogg.h";
This function forms packets into pages, similar to ogg_stream_pageout(), but allows applications to explicitly request a specific page spill size.
In a typical encoding situation, this would be called after using ogg_stream_packetin() to submit data packets to the bitstream. Internally, this function assembles the accumulated packet bodies into an Ogg page suitable for writing to a stream. The function is typically called in a loop until there are no more pages ready for output.
This function will return a page when at least four packets have been accumulated and accumulated packet data meets or exceeds the specified number of bytes, and/or when the accumulated packet data meets/exceeds the maximum page size regardless of accumulated packet count. Call ogg_stream_flush() or ogg_stream_flush_fill() if immediate page generation is desired regardless of accumulated data.
int ogg_stream_pageout_fill(ogg_stream_state *os, ogg_page *og, int fillbytes); |
Zero means that insufficient data has accumulated to fill a page, or an internal error occurred. In this case og is not modified. Non-zero means that a page has been completed and returned.
