Encoding with encoder_example
I have encoded successfully a YUV stream by using the encoder_example. Can We encode a row stream (get from a web cam) by using encoder_example. If we can not, is there any other way to encode a row stream by using theora codec. -- Nuwan Millawitiya -------------- next part -------------- An HTML attachment was scrubbed... URL:

Get start with Theora.
Hi, I am a beginner for theora. Now I am trying to understand the code of theora codec. If you can show me the correct path for understand the code (which codes must understand first), it may be easy to understand code properly. -- Nuwan Millawitiya

More information on GSoC project
hello everybody, I would like to participate in GSoC 2008 program under xiph.org. I went through the open project list[1] and found the project " Theora encoding support in GIMP" proposal interesting. I'd really grateful to you if you can give me more information on this, including 1. Why GIMP need encoding support? 2.If you have any guidance in integrating encoding support for GIMP

a question about Bitstream Header.
Hi, I have a question about the format of Theora bitstream header. It seems to me that there are differences between the specification[1] (version 2004 Oct 1) and its reference implementation in libtheora 1.0alpha3 released at 2004 Jun 1. I mean that... please refer to Section 6.2 'Identification Header Decode' in that specification[1] and the function

Error in Spec of theora ident header
While trying to find a bug in my encoder, i came across an error in the spec where it defines the structure of the ident header... the spec defines 100 extra bits which aren't actually in the headers... NSBS, NMBS and NBS don't appear in a 3 2 0 header... the actual structure is as follows //0 - 7 header ident (8 bits) //8 - 55 theora ident (48 bits) //56 - 63 ver major (8

Theroa Guess Confirmation
Hi there, is there any document giving a high-level overview of how to use "libtheora"? As it stands, I'm scrounging through headers and example code, and doing a whole lot of guessing. In the meantime, could you either confirm or deny the following guesses? 1) Before compressing with Theora, I must unpack my YUY2 data into three separate arrays (Y, U, and V respectively), and

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.

NOKIA E series Phone for SIP-VOIP calling
Hi i want to Buy Nokia E series Phone which have InBulit SIP-VOIP Calling client so i can make VOIP calls thru that phone. Aslo that Phone easly able to register with Asterisk Pbx to recive inter-office calls. i try to search from web & also from Nokia site but they only mention this features as "VOIP call from wifi" they mentioed only this much info. they not mentioed info about

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

mondo Centos4
I had asked a few months ago if anyone knew if mondo is compatible with CentOS4. One person said it was still working, but never mentioed if he had done a restore. I had the stable version installed and whenever I ran it there were a few messages about command not found. Well, I had a HD go out and tried booting from the CD and it failed. It was just my desktop PC and my home dir was backed up a

Current echo status?
I've been following the list for months, and I have a working Asterisk setup, but it'd be *really* useful to me at this point if someone could summarize when Asterisk has echo problems and when it doesn't. For instance, I usually hear a far-end echo when talking on my 7940, but not when using a POTS phone plugged into a TDM400 FXO port. It doesn't seem to matter if the call

Coded Order vs Raster Order
Hey, I'm not sure which mailing list this belongs on most, please correct me if I'm on the wrong one. I'm working through the Theora spec and trying to build an implementation as I go along. I have a few questions that I couldn't quite work out from the spec or in any online information that I found. The first question I have is related to coded order vs raster order. I

Thusnelda - Floating point exception in encoder_toplevel.c:209
Hi all, I've been hitting the odd floating point exception errors using the new alpha encoders. They're encoding a live stream so I can't reproduce the crash on demand, and it might only happen once every few days so it's been fun trying to get a backtrace. The crash happens in a fairly scary block of code, I wouldn't have a clue where to begin trying to fix it!

change uid/god below 100
Hi. Only indirectly related to zfs. I need to test diskusage/performance on zfs shared via nfs. I have installed nevada b64a. Historically uid/gid for user www has been 16/16 but when I try to add uid/gid www via smc with the value 16 I''m not allowed to do so. I''m coming from a FreeBSD backgroup. Here I alter uid using vipw and edit /etc/group afterwards. -- regards Claus

metadata switches for ffmpeg2theora
Jan, Here's a hacky patch to add a few commandline options for setting comment header fields in ffmpeg2theora. It's a bit big because I virtualized the global info struct in theorautils.c. In retrospect that probably wasn't necessary, but I think it's cleaner anyway. I didn't test it because I couldn't compile ffmpeg2theora, but modulo bugs it should support

Fix a bug that causes the encoder to spend way to many bits on keyframes
Here is a fix that prevents the encoder from spending too many bits on keyframes. The main problem is that the old code computes the target keyframe bitrate incorrectly. This causes the code that computes the Q for the frame to think that it has tons of bits to spend. It selects a high Q value for the keyframe. Since so many bits were spend on the keyframe the the inter-frames have to use a much

Patch that fixes distortions during static scenes
Here is a patch that fixes distortions that appear during scenes with no motion. Tbe problem was that UpdateFrame() was not being called when a MotionScore of 0 was computed. Since UpdateFrame() was not called the buffer returned by theora_encode_packetout() would be the same buffer that was output for the last frame that had a non-zero MotionScore. This is obviously incorrect behavior. I've
