similar to: ogg packets get lost

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

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

Hey all, If my understanding is right, there's a serious big in vorbisfile.c, in the routine _fetch_headers(), which will only show up when comment packet spans multiple pages. The code to read the first 3 Vorbis packets ogg_stream_pagein() once, then calls ogg_stream_packetout(). The problem is that ogg_stream_pagein() only adds a single page to the ogg stream state, whereas

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)

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

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:

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

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

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

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

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

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

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.

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

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

Hi all, streamnik started a new video streaming internet service (IPTV-Stations). We have actually started the "testing" period and would like to encourage some theora/vorbis/ogg developers to test the stream against various players for any problems. if you like, visit: http://www.streamnik.de Actually the page is only in german, however we are working on an international page.

I guess I'm missing something since the following minimized test case is failing: >>> #include "ogg/ogg.h" main() { ogg_sync_state the_ogg_sync_state; ogg_sync_init(&the_ogg_sync_state); ogg_sync_destroy( &the_ogg_sync_state ); } >>> $ gcc -g -logg test.c $ ./a.out *** glibc detected *** ./a.out: munmap_chunk(): invalid pointer:

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

Hi everybody, I've had some time and so I added a slideshow creator with the Ken-Burns-Effect to the Ogg Video Tools. Feel free to visit the following page: http://www.server.streamnik.de:88/test.html It's best viewed with the Mozilla Firefox 3.1 Beta 2, but a Cortado Player is also available for the other browsers. The code is actually not publically available, as I would like to add
