Hi,
Does anybody knows, how I can produce raw vorbis packets from an audio
stream without using ogg stream?

But the packets will be useless if simply appended to one another. They must go into a container that provides framing of some sort as they provide no means of finding beginning and end within themselves. Monty
Ok, thanks. What API can I use. Is there a sample somewhere?

Is there a sample somewhere?vorbis_bitrate_flushpacket() returns an ogg_packet structure with the encoded vorbis data. This includes the length and raw packet data, which you can use directly instead of packing it into an ogg stream. see encoder_example.c in the vorbis source examples directory. If you wanted to work with an already created ogg vorbis stream, look at decoder_example.c You can use similar code; ogg_stream_packetout() returns a similar ogg packet structure; just put that into your other container instead of passing it to the vorbis decoder as in the example. Hope that helps, -r
