Okay, how do I drop a changeset/patchset/tag for you folks from SVN? At this point, I have written three examples of how to use the basics of the ogg streaming and decoding in Tremor. I heartily welcome any suggestions, improvements and corrections that you can point out in the code. The examples required me to make some small modifications to the main tremor library. However, the changes

It seems to me that running ogg_sync_pageout doesn't automatically advance the page. This is good if you haven't worked with the given page, makes coding somewhat easier. However, when does a page advance. Is it after a call to ogg_stream_pagein? On a side note, I need to do seeking on top of libvorbis, I'd love to use vorbisfile but sadly I can't. Is there a reasonable way to

hi all: i downloaded libtheora1.0.tar.gz from xiph.org, and when i compile it, such error message popped. i tried to run player_example.c under /libtheora_1.0/examples/. error message: ivysummer at ivysummer-desktop:~/??/libtheora-1.0/examples$ gcc -o player player_example.c /tmp/ccpyle3c.o: In function `buffer_data': player_example.c:(.text+0x15): undefined reference to

I'm currently working on a speex + theora webchat. I have both working alone, but to make them work together and to know where the package goes, I'm trying to use ogg packages. With theora there has been no problem, but with speex I can't make it work. The problem is that for a second it works great, but then it begings to gain lag, and in a little time it has 5-10 lag seconds (into

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:

Hello, I'm new to this list, and pretty much also to the codec universe. In a computer game I'm working on, there is an 3D TV-screen onto which I project the frames of a movie. The movie is of course stored as theora, no audio as it's not needed yet. I have it working so far, extracting a frame and uploading it to the graphics card when the scene is drawn. The example file

What exactly does it mean when, in the decoder_example.c file, you try to extract the information from the comments and codebook headers and you loose sync? What is actually being check to determine when sync is lost?. I known one part of it is that there is a gaps in the stream. Is the CRC value the determining factor? Please detail! I read a lot of the documents. I still am a little fuzzy.

Ok I just finished writing a Vorbis encoder/decoder, and here are some of my comments (I'm sure some of these are well known, but here they are anyway - sorry this is long): 1. vorbis_info: a. Accessing the pre-computed info structs through pointers to static data is messy IMO. I should be able to vorbis_info_init (or similar) an info struct to be exactly the same as info_A, for

dear list, i am trying to write a small program which reads an ogg file and writes it to another ogg file (and changes serial number, granulepos etc on the fly). reading the ogg file is ok (ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout). but writing the file doesn't work - the granulepos and page structures don't match with the original file. here's what i am doing.

Hopefullly this is once again something trivial I'm missing. I'm still trying to figure out how to pull a part a stream. I get two out the three theora headers I can see in the file (http://v2v.cc/~j/theora_testsuite/320x240.ogg) if I use the buffer in the page struct and nothing usable if I try to use the packet structs. Hopefully this is once again something something trivial I've

Hello all, I'm currently in the process of implementing a mixing matrix into the header of OPUS files for the proposed channel mapping 3 seen here: https://tools.ietf.org/html/draft-ietf-codec-ambisonics-03#section-3.2 My implementation simply replaces writing the stream mapping char array with the Q15 col-wise matrix vals described in the above document. I'm able to write/read matrices

Good day. I have some questions dealing with merging Ogg Vorbis files. Suppose I want merge two Ogg Vorbis files encoded with the same parameters into one file that composed of one logical bitstream. In this connection some questions: A) Are codebooks in file headers depend only on Vorbis version and encoding parameters and don't depend on the particular source file? B) Are the following

If by webchat you mean anything interactive, then I can already tell you what the problem is. TCP+Ogg. For anything real-time, you want UDP/RTP without Ogg. Also, you need to take into account the fact that computers do *not* have accurate clock and their soundcards drift. None of these problems are fatal, but you need to take that into account in the design. Jean-Marc On Mon, 2006-08-07 at

Hi, I was wondering what oggz_get_bos and oggz_get_eos are supposed to do, specifically are they meant to be used in oggz_read mode? The documentation says "Determine if a given logical bitstream is at [bos/eos]". However if get_bos is given a specific serialno it returns that stream's b_o_s flag which, in read mode, is set on initialisation. The serialno=-1 (for all streams)

Hi. Le duodi 2 frimaire, an CCXIV, Wesley J. Landaker a ?crit?: > speexenc always crashes on amd64; here is an example, and lots of info: I tracked this bug a bit further than you. Here is the origin of the crash: op.packet = (unsigned char *)speex_header_to_packet(&header, (int*)&(op.bytes)); (from speexenc.c) op.bytes is a long, not an int, it is wrong to pass it as an int,

Hi, I'm the main author of Speex (http://speex.sourceforge.net), an open-source speech codec that uses Ogg for file storage. I'd like to have feedback on the way we store Speex data in Ogg files to make sure we do the right thing. The Speex documentation can be found at http://speex.sourceforge.net/manual/ but here's the part about Ogg: <p><p>Speex bit-streams can be

Hi! In my current occupation, it's necessary to access a lot of windows machines remotely. All they have a radmin ( http://www.radmin.com ) server installed. I would like to access them from my Linux box, so I've installed a windows radmin client on the box and tried to use it. The first impressions were great, because it installed perfectly (I didn't attempt to install the server,

sorry, no webchat, is a videoconference program. And I'm using UDP as you can read down on the mail. The problem is that speex packages alone work great, but to split speex/theora packages on the arrive I need to use some kind of container, and I'm trying ogg.
