Live Streams
Hello, i am member of red5 project. I am studying ways to integrate your codec into red5 and in a near future inside Flash Player. I want to figure some things about Theora codec. -> Is theora proper for live streams (i.e live transcondig webcam)? What is latency for encoding process? -> Is the format tolerant to lost frames? Thanks for the moment.

Theora blurriness in Windows players

[LLVMdev] How to compile a simple C program with clang on Windows 8.1?
Hi all I need a small help to get my first C program to compile on Widows 8.1. I'm an Unix guy but new to Windows. I installed MS Visual Studio 2013 free version and the LLVM 3.6.0 binary pre-built version. Here is my sample C program: #include <stdio.h> int main() {   printf("hello world\n");   return 0; } 1. >clang test1.c -o test1.exe test1.c:2:10: fatal error:

[LLVMdev] multithreaded performance disaster with -fprofile-instr-generate (contention on profile counters)
Hi, The current design of -fprofile-instr-generate has the same fundamental flaw as the old gcc's gcov instrumentation: it has contention on counters. A trivial synthetic test case was described here: http://lists.cs.uiuc.edu/pipermail/llvmdev/2013-October/066116.html For the problem to appear we need to have a hot function that is simultaneously executed by multiple threads -- then we will

How to write a catch all rule?
Hi all I''m new to Qos and iproute2, but studied well the documentation. According to http://lartc.org/howto/lartc.qdisc.filters.html, catch all rule should be written as follows: tc filter add dev eth0 protocol ip parent 10: prio 2 \ flowid 10:2 But it doesn''t work because filtertype is missing.

encoder_example input formats
Hi all I have the raw out put of a video camera in following format: mjpegb, yuvj422p, 1920x1080, 24.00 fps(r). I cannot directly convert this raw footage to Theora due to the YUV4MPEG2 only restriction of the encoder_example. Isn't it better to support other raw formats in encoder_example, such as what I have, mjpegb, yuvj422p? I presume even if I convert the mjpegb, yuvj422p to

VirtualDub and enconding with DivX, XviD
Hello, I am trying to get the latest wine (Wine 20030219, fake windows) working with the GordianKnot (0.27). Unfortunately, Virtual Dub is not be able to compress a avs-file with the DivX-codec. It crashes if trying to. Also, it would be nice to compress an mpeg-source with Xvid but also it crashes. BTW, VirtualDub does not list it in its codecs window ?f "msvfw32" is set to

Java and ogg/vorbis
I am a bit confused to how Ogg/vorbis works. This is my understand. Vorbis is an audio codec that can be used instead of MP3 and it is open source. If this is true, what is Ogg? I think it is some kind of wrapper that allows you to stream Audio and Video. Am I right? Also I want to encode short videos in Xvid and then encode the audio in vorbis. Then I want to stream this over the Internet

[PATCH] Fix for YUV4MPEG support in encoder_example
As was briefly discussed on IRC, ffmpeg and mplayer currently output two somewhat incompatible YUV4MPEG streams. This meant that encoder_example could take input from mplayer, but not ffmpeg or movtoy4m (a QuickTime->Y4M tool). This is a patch that fixes this issue and should allow encoder_example to take input from either format: diff -urd xiph-cvs/theora/examples/encoder_example.c

Create CD from avi files
I have avi files in xVid format from my Camera, and I want to create a Video CD that can be viewed on any CD player. I have searched through the various repos (including rpmforage and kbsingh) and did not find anything that would burn. I have a number of programs that have no trouble displaying these files. Including xzine, Avidemux, and VideoLAN-Client). I unfortunately have to make these

MemoriesOnWeb and wine
In http://www.edsupport.cc/mguhlin/archives/2007/08/entry_3550.htm, Miguel Guhlin asked how to install MemoriesOnWeb and its recommended codecs under Wine, so here goes. All I did was translate his instructions to wine-ese. 1. Download xvid for windows from http://www.xvid.org/Downloads.15.0.html, install it the obvious way: $ wine XviD-1.1.3-28062007.exe 2.

Theora encoder performance
I'm evaluating some video codecs for a online conference system. I'm encoding images (640x480) from a webcam. I've been playing around with theora and xvid. First of all, using theora, the decoded image looks strange: http://integrasoft.ro/~mgliga/theora/comparison.png <http://integrasoft.ro/%7Emgliga/theora/comparison.png>.

mpeg4/xvid/divx vs. theora
Hi there, I have an elementary question. Although theora can be placed in the same class of codecs as MPEG-1, -2, -4 why is there no greater usage of this codec? On the bigger part of web sites trailers or short videos are encoded with some mpeg codec. Why is theora still so rarely used and unfamiliar although it perfomes very well from my point of view? Is it, because - the whole mpeg family is

[OT-ish] WebM/Ogg VP8 streaming
Hi all, Sorry for the VP8 question on the Theora list, but I think all the relevant people are here :) I'm using Icecast to distribute some Ogg Theora streams at the moment with a view to adding VP8 along side these in future. Ideally I'd just use Ogg VP8+Vorbis, I know there is a mapping for this already but how much support from the browsers can I expect for this configuration?

On your document here: http://web.mit.edu/xiphmont/Public/theora/demo.html you show the result of the improved rate managemet in the theora codec.
