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

Hello everyone, I'm programming something using ogg vorbis and i was wondering how I could get a packet from a logical bitstream when this packet is over several pages. let's say I made a call to ogg_stream_pagein, then ogg_stream_packetout, but the packet is incomplete and continued in the next page(s). If I get the following page and I call ogg_stream_pagein again, how can i get

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

Just to make sure, if I'm mixing 2 streams at the page level, and using ogg_stream_pagein() and ogg_stream_packetout() to extract them, I need two ogg_stream_states, one for each logical stream, and I need to ensure that each ogg_stream_state only sees pages of it's own type, is that right? - Martin --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

ok, I'm aware that vo_open cant be used at the same time as other functions such as ogg_sync_wrote, ogg_sync_pageout, ogg_stream_pagein, ogg_stream_packetout and vorbis_synthesis_headerin. In order to get information from the bitstream i've been using this method because it's fast and doesn't require decoding of the stream. But, i can only retrieve the average bitrate of

Hi, I am actually working on a c++ wrapper for ogg/theora. It will be a small library to easily create command line tools to cut/cat video-files and to extract and join the video and audio stream etc. However, I started the project and found some very strange behaviors: I stored some ogg_packet objects (which are created on the heap) in a list. When I make several calls to ogg_stream_pagein()

Hello Conrad, I'm trying to seek the way you told but I'm facing a problem. ogg_page_packets returns 164 and following code returns 189. Shouldn't it be the same, what does that means ? int res; while (true) { res = ogg_stream_packetout(&os, &op); if (res == 1) nPackets++; if (res == -1)

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

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.

Hello, This is the code, it's a little crap but only to see if it works. I assume rate = 16000 and frame_size = 320. if (this->seek_to != -1) // SKIP { ogg_int64_t max_units; //max_units = speex_seek(fin, this->seek_to, 0, rate); int nPages = 0; int nPackets = 0; // Pone el cursor en la posici?n inicial del fichero fseek(fin, 0, SEEK_SET);

Hi, I put together a small a Visual C++ 6.0 project that uses the code from vorbisfile_example.c. I open an ogg file in binary mode and when ov_open gets called, it always fails. I then put together another project and compiled vorbisfile so I could see where the error was occuring. It is happening in _fetch_headers when it calls ogg_stream_packetout. The return values is -1, which means there

I am trying to create a Graphical User Interface for a Vorbis Player under MS Visual C++ 6.0 I was initially trting to use the code from decoder_example.c but I keep getting linker errors. I have set up my project as told to by James Boer on this mailing list. This is as follows: This document was prepared from an email received from James Boer on the Ogg Vorbis mailing list. It gives a

Dear All, I am trying to cross compile the dependencies of ices for arm linux. I have been able to compile libxml2 (2.6.32) and libogg (1.1.3) successfully but I am getting stuck at compiling libvorbis (1.2.0). Making install in examples make[1]: Entering directory `/home/sr/armlinux/stream/libvorbis-1.2.0/examples' /bin/bash ../libtool --tag=CC --mode=link /usr/local/arm/bin/arm-linux-gcc

Ah, OK, I understand where you're headed now. The libvorbis API is different than

I downloaded libogg-1.1.2 and libvorbis-1.1.0, and want to compile them using mingw32. In libogg-1.1.2 directory, 'sh configure --prefix=/mingw' and 'make' and 'make install' works smoothly. It create libogg.a, ligogg.dll.a, libogg.la in my /mingw/lib and header files in /mingw/include/ogg, so I think the gcc compiler will find them easily. After switching to

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

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

I'm trying to adapt decoder_example to to support more of an event driven model. I'm building an RTSP client/server where the client will have a function called everytime a new packet comes in. So, I want to queue up these packets to be played. My current attack is as follows (note this isn't very robust and I realized that): For first and second packet i grab all the header stuff

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

I wish I would have come across this in time for the libogg-1.1.1 release... Maybe I'm doing something wrong but here it is. One FLAC compressed frame becomes one packet when encapsulated in Ogg, and FLAC packets can be much larger than the nominal 4k page size. For CD audio they are usually 10-15Kbytes. Imagine this Ogg stream where the lines denote page boundaries and the x's are one
