theora_info struct question
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 */

Trying to do windows encoding dll
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

libtheora test suite
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

Simple encodig sample...
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

impossible to link against libtheoraenc (missing symbol th_comment_query_count)
I've got a huge problem with libtheora. All is fine if I link only against libtheoradec but as soon as I try to link also against libtheoraenc everything breaks down: libtheoraenc.so.1 dlerror: libtheoraenc.so.1: undefined symbol: th_comment_query_count. I've checked with NM to see how the libraries depend on each other: nm libtheoraenc.so.1 | grep th_comment_query_count

Encoder init
Well, as you may have seen from my previous messages, I'm doing a webcam stream program. The encoder is working well right now, but I'm having some hard time with the decoder. I know the parameters used in the encoder, and they are not gonna change, so I want to init the encoder directly into the client. The problem is that if I give the values to theora_info and after that I call

V4L + Theora small app...
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

[Doc] theora_encode_init problem
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

decoder init/clear
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

Theora 1.1 rate controller
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.

theora-exp namespacing
All, There was a discussion on IRC yesterday about cleaning up Derf's theora-exp implementation so it can be used in frameworks that also link to libtheora. The encoder doesn't work at the moment, but the decoder is faster and implements more of the spec than libtheora, so this would be a useful option for people trying to deploy players. The main thing that needs to be done is to

library migration plan
Derf (Timothy Terriberry) and I talked about the api transition plan on friday. The plan is: * libtheora will export only the "old" api, as it did in beta1. * libtheoradec will export both the "new" theora-exp decoder api, and the decoder portions of the old api. So libtheoradec will be a drop-in replacement for decoder-only usage of libtheora, and the linking change will

theora problems
Hi, I've been trying to use libtheora-experimental (libtheoraenc and libtheoradec) to encode a webcam feed in real-time, to be decoded also in realtime by a second party via XXX-IP, with - unfortunately - not so good results. I'm using custom written functions to convert from RGB8 to YUV420 and back and, although not much processor-efficient, they do what they're supposed to

Legalese. What is stride?
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

Bitrate Adaption
Hi, I've been reading through the Theora format spec and API reference trying to find an answer to this but haven't come across anything certain. I'm wondering whether it would be theoretically possible to change the encoded bit rate (or target video qiality) during a live stream without a standard theora decoder having any problems. I had assumed that this must be possible, given

FFmpeg Theora encoding patch
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, and thank to you all for this great codec ! I have this bug on Debian Lenny with compiled packages of last svn versions of ffmpeg and libtheora. This seems to append only on the amd64 arch.

libtheora Bitrate Problem

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
