Hi, I wrote a plugin to enable LiVES (a video editor) to encode theora/vorbis/ogg files. I'm looking for some advice towards improving quality. If someone would like to help me test this please note that you'll need MPlayer, ImageMagick, sox, the encoder_example from libtheora (somewhere in the PATH), and Python 2.3.0 (this is fairly all standard stuff). Consider the following clip:

Hi, I sent this message to the theora list but I'm not sure if it got through (activity seems to be very low, regardless). I'm hoping I have better luck here.

After a bunch of cumbersome testing I was able to transcode a Quicktime MOV file to OGG with theora and Vorbis. The method's a bit fumbly, but it works... It is automatable except for the initial audio decoding. Software used: Xine, oggenc, ffmpeg, ffmpeg2theora, oggzmerge Step 1: Get the video out of Quicktime ffmpeg -i infile.mov -b 5000 -f mpeg2video outfile.mpg Step 2: Get the video

Everyone, I've made a new release of our libtheora reference implementation. This draws a line under all the development since alpha 4 before we start merging in the optimization work people have been doing. It also contains a fix for two serious bugs (one an encoding error, one a segfault) so we recommend everyone upgrade. The release is source and binary compatible with 1.0 alpha 4.

Hi, Is anyone able to help Mr Stoner? -Ivo ---------- Forwarded message ---------- From: Ed Stoner <ed@whsd.net> Date: Oct 9, 2007 5:32 PM Subject: [sugar] video encoding To: sugar@lists.laptop.org I would like to provide the functionality of a "video export" from within an activity I am working on.

Hi, I didn't get to the bottom of it, but Valgrind is whining on libtheora when encoding a video to a 16 width or 16 height video. While you may think I'm weird for encoding to such a size, I didn't care about the output video, but I reckon it should work. The bad accesses seemed to be of pixel data, in FilterVert__c, and in FilterHorz__c (from memory), but I didn't investigate

Hello. I'm trying to encode an Ogg Theora file from an unencrypted dvd using mplayer and encoder_example. I set up named pipes stream.wav and stream.yuv. I then run: mplayer -ao pcm -aofile stream.wav -vo null /dev/dvd & mplayer -vo yuv4mpeg -ao null -nosound /dev/dvd & encoder_example -v1 -a 1 stream.wav stream.yuv > lec1.ogg but I get the following error: File stream.wav is

Hello, Could you kindly point me to some instruction, how to encode demuxed files (.m2v and .mp2) to .ogg (Theora + Vorbis)? I was trying to use ffmpeg2theora, but I don't know, how to put two files to ffmpeg2theora (one audio an one video) and did not found, how to mux them into one file? Exist a way, how to do two pass encoding? I'm using Ubuntu Fiesty Linux. Thank you, Jiri Navratil

Okay, thanks to some stubbornness on my part and helpfulness on the part of people on this mailing list, I got the Ogg Theora alpha compiled up and installed and running. Yesterday, I went to the Prelinger archives (the public-domain video archive at www.archive.com) to find a high-quality original to re-encode as a test. The encoder worked just fine, and playback as well, and I thought I'd

Greetings, I was on IRC about 7 hours ago and suggested that the FAQ be updated slightly. Rather than sit on my ass and complain I figured I'd ask a few people, and see if the idea was worth the time. Here's what Ive started with: http://www.dimension.net.nz/theora.html I'll be adding to it over the next 24 hours - mostly in the area of Playback and Encoding. Just threw it together

Along with libtheora-1.0alpha5 this is a release of theora-mmx. A drop in replacement that uses MMX assembly to speedup some of the most demanding routines in theora encoding/decoding. Right now it only works on 32bit x86 CPUs. Thanks to everyone whose work made this release possible! Download links: http://downloads.xiph.org/releases/theora/libtheora-mmx-1.0alpha5.tar.bz2

As requested by Ralph in my introduction e-mail to this list [1], I've gone ahead and done some sample test timings for encoding between libtheora-1.0 and libtheora-1.1beta3, as available from the Theora website [2]. So far, I've tested with 4 different files that I generated with content I already have. The files, in brief, are the following: 1. planet-earth-360x240.yuv4mpeg - A

I am trying to gauge how much interest there is in supporting non-8- bit byte targets. Other than myself, Ken Dyck of ON Semiconductor has a 24-bit machine he is trying to support. We have been working jointly on this but we are also both new to Clang and LLVM. Although both of our processors are not mainstream, Ken points out that Texas Instruments the C5000 series is also 16-bit

i am new in this mailing list i have written a script for theora (i am not sure that it is useful or not ? ) ========================================== #!/usr/bin/perl # ALL2theora based on Florian Schilhabel <florian.schilhabel@web.de> dvd2divx script (was under GPL) # we have made major changes to that script and now it can convert almost all video format to theora # all2theora depends

Hi, I was playing around on my laptop last night and installed the 8.41.7drivers from ATi, my laptop has an X1400 in it, not the HD2400 that the drivers were designed for so I understand some things may not function correctly and will cover the observations: 1. Pixels shaders+Vertex shaders - I have to disable these or I get missing elements from the screen, once tunred off it all renders ok 2.
