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.)

Hi Developers, I have a 16-bit PCM data buffer, I want to write that to ogg file. Could you help me to understand how to write pcm data to the ogg? Thanks in advance.

...back), except that no matter the length of the source PCM file, the last (approx) 4 seconds of audio is always missing from the Ogg file. I am trying to find some documentation that details some of the functions used (e.g. vorbis_analysis(), vorbis_bitrate_addblock(), vorbis_bitrate_flushpacket(), ogg_stream_packetin() etc.) as I am sure its just some sort of flushing problem, but I'm not having much luck. So does anyone know the cause of my problem, or where I can find some documentation. <p>Thnx, Dave <p>The information contained in this email and any subsequent correspondence is private an...

I was wondering. When doing ogg only encoding, how do you mark end of stream? I am setting ogg_packet.e_o_s and then submitting it via ogg_stream_packetin() and then, because its the last potential page ogg_stream_flush()ing it. But when I walk through the file, EOS is not set on that logical bitstream. I have been using oggenc.c/encoder.c and oggdec.c/decoder.c for examples, but because the packet assembly is done down in the vorbis stuff, I havent...

...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) - next pages with same serial number are handled equivalently: stored in ogg_stream_state using ogg_stream_packetin to add them to ogg_stream_state and using ogg_stream_pageout to get ogg encapsu...
