Enabling the following function in tests/noop.c: noop_test_decode () { theora_info ti; theora_state th; theora_info_init (&ti); theora_decode_init (&th, &ti); theora_clear (&th); theora_info_clear (&ti); } segfaults. The cause is that theora_decode_init() expects a theora_info structure which was previously initialized by passing actual bitstream data through

Hello. How can I tell the number of frames in ogg/theora video file, without actually reading the file? Or, how can I tell its playing time (which is basically the same thing). I didn't find the information in THEORA_STATE, THEORA_INFO, but with the codec installed (illuminable oggcodecs), Windows Media Player shows the ogg/theora file playing time, before it starts playing the file.

I found a bug in theora_decode_init when I was implementing the decoder. theora_decode_init should be zeroing the theora state structure right? memset(th, 0, sizeof(theora_state)); // Erik -------------- next part -------------- An HTML attachment was scrubbed...

Hi everybody, me again. I'm trying to write my own VFW-like dll... It doesn't need to do much. 1.) compress a single frame and give it back to the host application 2.) host applications sends the frame 3.) client application receives frame 4.) client application tells the dll to decompress the data So if I try to do this, something is going wrong... Perhaps someone could have a look at my

Hi, I just committed the framework for a test suite, and a couple of small tests, to libtheora (changeset:9700). The tests live in a directory called tests. When building with GNU autotools: * 'make check' will run the test programs listed in the TESTS variable in tests/Makefile.am . 'make check' will fail if any tests fail. * 'make distcheck' will fail if any

Hi, Ralph recently checked in a version of theora/tests/noop.c that uses the new API. Part of the reason for this test is to check for memory leaks in the library's constructors and destructors. You can run the test suite under valgrind by configuring with --enable-valgrind-testing. The test passes, but gives output like: make[1]: Entering directory

Hello everyone, I'm currently developing an adaptive videoconferencing application based on Ekiga which uses TFRC as a congestion control mechanism to adapt the video encoding rate according to the quality of the network experienced. My goal was to use the open-source Theora codec for video transmission. Unfortunately, it seemed that Theora 1.0 did not properly implement any correct CBR mode.

Updated version of video preview covering frame writing every 3 keyframe and a xsl typo. Best regards :) kysucix -- Make things as simple as possible, but no simpler. - Albert Einstein

Hi. Here it is my patch to put a video preview of a theora stream in status.xsl. I just added a: <video-preview>1</video-preview> parameters in icecast.xml.in that control the previewing function. It encodes a png in $webroot/$mountname.tmp and then move it to $webroot/$mountname.png As for now it saves a frame every theora keyframe, which is probably too heavy for the server but

Well, finaly I have something pretty usable working. Actually it only works if you have installed .Net 2.0 but I'll try to fix this and add a Linux and OS X version. Try it and give me some feedback :P http://www.alu.ua.es/j/jma27/VideoChat.rar -- http://www.apple.com A veces me da por ahi.

Hi all. I'm Mat & I'm new :) I'm testing libtheora + libogg perhaps for a commercial product. I started watching encoder_example.c ... I simplified it for testing it easier. It seems ok to me but I have no experience with theora so I would like to know if my code is correct. I tried to debug it with Valgrind and I found 4 possible memory leaks... but I think they can be

Hi I'm evaluating Theora for a video communication system and would like some info as to what the following struct members (from the theora_info structure) do and what values one should pass to them: If there is some documentation somewhere that I've missed, please direct me to it. ===== Extract from theora.h ===== int quality; int quick_p; /* quick encode/decode */

Hello all. I've been playing around with theora since it first entered CVS, and I like what I'm seeing. Today I've been fixing xine's theoraplugin to understand theora_info.frame_{width,height} and theora_info.offset_{x,y}. I only got it working after some experimenting and basically copying the code from player_example. A few questions related to this: 1. What are the legal

Hello, I'm not sure if this list is the proper place for this post; please correct me if it is not. I am attempting to use libtheora and I have been looking through the examples in the distribution Excerpt from encoder_example.c -- case 'V': video_r=rint(atof(optarg)*1000); if(video_r<45000 || video_r>2000000) { fprintf(stderr,"Illegal

Hi I'm new with ogg and also with using third party libraries. I'm making a C++ PocketPC program and I need a simple wav->ogg encoder function. But as I have tried to use ogg vorbis libraries I don't know what or how to use them. I think that best way would be to use libogg 1.1.3 and libvorbis 1.1.2. Do I even need both of them, since I only need to have capability of

Hi all. I post a small app I made that create 2 clips using a V4L device. I would like to get every tips you think it's useful... Some notes: - I make 2 clips because in our project we create series of clips and it's important to check that the all the resources ( memory, descriptors, etc. ) are freed correctly and to reuse all the resources that can be reused - the clips are not well

Hi, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

Hi, My name is Patrick, i am french, and i am developping a softphone for pocket PC using speex. Sorry in advance for my bad english. So i have make an GUI in C# that use the speex functions through dll write in C++. And the encoding and the decoding using speex seems to work not too badly.(i test with a wave file) My problem is that i need to get audio data from the microphone. In order to do

Hello, I recently decided to develop a client-server visio-conference app for windows using libtheora for network communication. But I have a problem initialising the theora encoder : theora_encode_init() returns -23 and I would like to know what it means all I could find in the doc is that it should return 0 in case of success. I understand my call to theora_encode_init() failed, but i'd
