...Estimated Hours: 0.0 I have a system which receives large SIP message ( > 1500 bytes). After upgrading to latest Ubuntu 11.04 release (Linux kernel 3.0.4), SIP calls to my router stops working.

So, I abandoned the hope of using the ogg python bindings to do pure ogg container encoding. I started looking at the libogg in the hopes of retooling the bindings to follow a better object model and it actually looks like the problem is down in libogg, not the bindings. Am I crazy or does libogg rely on libvorbis to return ogg_packets, and that there are no functions that will build an ogg_packet

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 pag...

Dear theora developer community, currently I'm working on a simple Theora player for Windows. But the code in the player_example.c seems not to have the performance of other implementations like the Direct Show filters by illuminate. In the example player, all important things are done in one thread: decoding the next vorbis or theora packet(s) and reading from the physical stream (+ split

...o save Ogg pages in an .ogg file playable by xmms, but that's no big deal. So what I'm doing is this. First the init part. a) vorbis_info_init b) vorbis_encode_init c) vorbis_comment_init d) vorbis_comment_add_tag e) ogg_stream_init f) vorbis_analysis_headerout g) ogg_stream_packetin for the header, the header_comment and the header_code Then the encode part a) sample pcm and hand it to encode code b) get buffer space with vorbis_analysis_buffer c) convert 16 bit signed pcm to float and place in buffer d) tell data size submitted with vorbis_analysis_wrote then go...
