similar to: ogg only encoding

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

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 pages can be

Hi. I'm trying to implement Ogg/Vorbis support for the MPEG4IP project. The goal is to support Ogg/Vorbis audio for MPEG-4 streaming. So far I have managed to make the encoder save Ogg packets as an Audio object in an .mp4 file. As a side effect, it can also 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)

Hi Vorbis-Dev, I'm investigating various WebM/Vorbis bugs in chromium. AFAIK muxing Vorbis inside of WebM does not have an official specification, so I'm using ffmpeg's implementation to try to answer 2 questions: 1. Under what circumstances is it valid to find WebM Blocks containing Vorbis data with zero duration? (This would mean the next Block in the Cluster has the exact

Hi, Searched in Google, browsed xiph vorbis sites but found no good information about how to get the current playtime out of the granuleposition of the ogg_packet. Anyone knows if there is any 'Programming with libvorbis' documentation out there, cause on xiph's site (http://www.xiph.org/vorbis/doc/) there's nothing :( Any help? THX, Tom

Hi. I assume that I am deeply stupid and have missed something obvious, but why does this bare-bones code not generate a valid (If trivial) opus file? Running opusinfo I ge the following which I interpret this to mean that not even the first packet gets a pass: New logical stream (#1, serial: 1f0cce42): type opus WARNING: Could not decode Opus header packet 0 - invalid Opus stream (1) WARNING:

Happy new millenium! Summary: I'm having a problem queueing up the ogg_packet results of vorbis_analyze() for later writing to an .ogg stream. The docs don't seem to say if this is permissable or not. Hence, I don't know if I'm using the API incorrectly, or if this is an actual bug. ----- Attached is a short patch to vorbis-tools/oggenc/encode.c (from CVS head, 01/01/01... I

I have been trying to get in contact with some of the pyogg folks via IRC and individual email, but have been having little success. I wanted to get some information about the svn commital/maintainers process.... Any information on where I could direct the questions would be much appreciated.

Hi While implementing OSS Ogg/Vorbis encoding and streaming using RTP/RTCP for both unicast and multicast, I have come across a few issues I need to clear out regarding the numbering of ogg_packets and their granulepos value. Below are the result for two different scenarios. <p>In the first scenario, ogg_packets are generated using a) vorbis_analysis_headerout() b) while

(Sending again after subscribing, I guess the moderator is on vacation.) I'm working on support for tagging Speex files for Mutagen[0] and part of the specification at [1] is confusing me. It says the first page should have granulepos 0 and packetno 0. Does this really mean page sequence number 0, since the Ogg format doesn't number packets? If it doesn't mean page sequence number,

I guess libogg should return -1 if you try to ogg_stream_packetout() after the eos packet. The eos flag pretty clearly applies to the *page* not the packet, so I think how that gets translated into the

Why do you not want it? It is just a simple C struct to carry the packet's metadata.

Using libvorbis (1.3.5) I wish to extract the raw vorbis packets.  I've built some simple code on the excellent libvorbis API overview on the xiph.org site, but the example relies on the ogg_packet struct for final output and input to decoder, and shows now examples on how to do without it. Taking a look at the vorbis_bitstream_flush() function, which in the overview is the last step before

Hi all, I try to compile speex for ARM. I follow the README.arm and i always have the same errors : make[2]: entrant dans le r?pertoire ? /usr/src/linphone/arm/speex-1.1.6/src ? source='speexenc.c' object='speexenc.o' libtool=no \ depfile='.deps/speexenc.Po' tmpdepfile='.deps/speexenc.TPo' \ depmode=gcc3 /bin/sh ../depcomp \

Can I join many ogg_packet together and decode it to PCM? Or I have to encode each ogg_packet at a time? If each packet is 1024 long, can I join 1.5 of packet (1024+512), and decode that 1024+512 packet, and then decode the 512 left? Or I must decode a whole packet, and can't cut it or decode only some of it (not all) Thank you, <p><p>--- >8 ---- List archives:

I'm trying to write an OS X AudioCodec for Vorbis using libvorbis. I'm confused about the libvorbis dependency on libogg. I thought the vorbis spec didn't require ogg as the container, but the

Hi, this problem seems to be coming up a lot lately -- the README.arm in linphone tells people to remove libogg headers, but speexenc and speexdec require them to build. Perhaps we need a README.arm in libspeex telling people not to remove the libogg headers. K.
