similar to: Theora Intra (ptalarbvorm) vs. MJPEG

In the discussion of having a freedom-friendly camcorder or other video device, we discussed the idea of using intra-only Theora video to make post-recording editing a much easier process, allowing things like frame-by-frame editing without the need to decode and reencode the video again, thus incurring loss. I was quite skeptical of the efficiency of intra-only Theora, and I had speculated that

Hey all! I'm sure you've all been missing my webcam stream, so I decided to start it up again (also, I wanted to do it for my family overseas). However, this time, I'm doing things a little bit differently. For starters, the encoder is the current (as of about an hour ago) ptalarbvorm branch which is destined to become libtheora 1.2. Another difference is that I'm using

Hi there, I was wondering if someone closer to the work happening in the Ptalarbvorm branch could be so kind as to provide a little update on progress? I've heard tidbits from around the web that the improvement over 1.1 is at least as much as 1.1 was itself over 1.0. I know that myself and many others found Monty's occasional updates on Thusnedla development to be absolutely fascinating

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Since I'm planning to finish my encoding tests that Ralph asked me to do a while ago after I return to the US (God-willing!), I thought I'd throw out a request to other more-experienced video folks. Please recommend to me any good sources (freely and/or legally available) that I can use for my testing of the encode/decode speeds as well as

I've compiled all the e-mails between me & MPEG-LA, along with an explanation and some major conclusions, here: http://www.librevideo.org/blog/2010/06/14/mpeg-la-answers-some-questions-about-avch-264-licensing/ Comments welcome, discussion even more so (preferably some of that on the site, too...). -- *Basil Mohamed Gohar* abu_hurayrah at hidayahonline.org

To my recollection, there hasn't been any talk about Ptalarbvorm. Is Ptalarbvorm development ditched? (I have noticed some commits for it every now and then, but nothing like the amount of commits last year) -- Daniel Hendrycks -------------- next part -------------- An HTML attachment was scrubbed...

ffmpeg2theora nightly builds found at http://firefogg.org/nightly/ still uses Thusnelda. Where can I get a Ptalarbvorm version for Windows? Regards

Our discussion in the "Theora Camcorder" thread has been great, but I didn't see a direction evolve for action yet. So, I'd like to propose the creation of a community website that will be focused specifically on this kind of thing, partnered with the Xiph Foundation. I'm also more than happy to host said website, as I have more than ample server capacity for that. I just

We're about ready to do a 1.2 alpha release from the ptalarbvorm tree, and as such it's no longer experimental. I've replaced the theora svn trunk with a copy of derf's experimental tree; please do subsequent development toward the release there. The old 1.1.x trunk is available as http://svn.xiph.org/branches/theora-1.1 if you need it. -r

Hallo all, i didn't found any deb packages for ptalarbvorm so i did it by my self. currently i do it in my playgrond here https://launchpad.net/~bug-track/+archive/ppa probably it will be better to add ffmpeg2theora too. I stated write scrip to do it regularity without big work overhead. any comments? Regards, Alexey

Hi! Just searched the icecast forum but didn't find anything, so I'll ask you. Do you know of a streaming server to take as input a mjpeg stream from an ip camera and transcode it to ogg[vorbis] and handle it to icecast? Please don't mention vlc. Already tried and every 10 sec it freezes and buffers. Just playing the camera in vlc works fine, but not transcoding and connecting

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

Dear All ... I have AXIS camera with output mjpeg format. I try to relay it to outside world using ffmpeg and it work The recipe is taken from http://www.daantje.nl/2007/05/07/convert-axis-webcam-stream-to-flash-swfflv/ Now ..

I just finished using my mother's PC which is running Windows XP. I downloaded & installed, or already had installed, the latest versions of VLC Media Player (1.0.5), Media Player Classic - Home Theater (last release was in August 2009), Miro (already installed), Mozilla Firefox (3.6), Google Chrome (latest from website today), Opera (10.50 Alpha, latest build from the website), and

Hello, Just a quick note, some people told me in the past that I must adapt NHW to any image size else nobody will consider and use it.That's certainly right, but again I am working on NHW on my spare time and this task is too exhausting for me.Also, I feel now that it is useless, as I have read that in the very next months, the great AVIF and JPEG XL will be definitely adopted everywhere on
