Hi So far when I have streamed Vorbis, the headers (the 3 first frames/packets) was not included in the stream, but communicated out of band typically in an SDP file as unparsed A-lines. Rethinking that concept, I'm wondering if it is really necessary to do it that way. Isn't it possible in a platform independent way to regenerate useable headers on the client side using just the

Hi I'm trying push for companies and government institutions to start using Vorbis as an alternative to MP3 and to some extend AAC so they as a benefit can ignore rigid license schemes and expensive royalty payments. In principle it ought to be a downhill job, but it has turned out to be a lot more difficult than expected. The biggest obstacle for government institutions and to some extend

Anyone else on the list using these tools? I grabbed the latest iteration using yum from Dag's repository, but I get random segfaults on a fully-patched 4.4 system on dual Opteron 275's from some of the utilities. Perhaps, it's some 64-bit vs 32-bit-ism? I'm not much of a programmer (actually, I'm a terrible programmer) so any suggestions would be very much appreciated.

Hi Fred. Appreciate your response. Maybe in my explanation I have some red and green apples, but I can agree that my understanding is as you explained it. 😊 The point is that if I can successfully stream mp4 with H.264 and AAC encoding without any issues to icecast, I can then use ffmpeg to turn it into HLS which then solves my iOS support issue. The CPU cost of repackaging MP4 into HLS

Hi Marvin I followed this advice for updating moov flags in mp4 and it "streams" directly from the file location on the server with html5 video: https://rigor.com/blog/optimizing-mp4-video-for-fast-streaming. Progressive downloading, seeking and video time all works 100% on a 195MB file. Regards On Wed, May 1, 2019 at 10:19 PM Marvin Scholz <epirat07 at gmail.com> wrote: >

Hello, You guys might want to join this discussion. (And maybe some others too.) On the WhatWG mailing list, there's been a fury of e-mails about adding a <video> element to HTML5. They're talking about codecs and containers now. It might be helpful to have your representatives there. And help shape things. See ya ---------- Forwarded message ---------- From: Dave Singer

Hi, How can I provide live mpeg4 feed to icecast2 ? I guess I will have a PAL composite signal or similar for input remotely. I will typically have a laptop with linux or windows XP available. I want to use a flash-player for viewing. Olav

I want to install mplayer but my GCC is 4.0. can not compile the mplayer. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20100824/86c613fd/attachment-0002.html>

I streamed Mpeg4 via QuickTime for several years using the encoder and Helios server. Worked great with a QT player so it can be done but I don't know of a way to do it for free.

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

Hi Fran, you could do it using Adobe/Macromedia Flash Media Server 2, but I guess that's not the answer you are looking for. If you manage to do this and release it under GPL I'll kick in $50 for a bounty.

Hi I was surprised with size of Theora files and thought of feedback. Following 1minute duration Theora and Xvid files were made from a y4m file. The resolution is 1280x720: 1. Xvid 17MB 2. Ogg/Theora Q7 31MB 3. Ogg/Theora Q8 38MB 4. Ogg/Theora Q9 49MB 5. Ogg/Theora Q10 61MB The Xvid file was made using mencoder by 2 passes with following options:

Create the ref_bo without any storage type flags set for now. This can probably be split up somehow later on, but this seems to work.

In order to do that, remove the if (chipset < 0xc0)

Hi, We are working on Oggvorbis encoder porting on embedded platform. Where can we find good test vectors (wav files) for testing OggVorbis encoder? Does anybody have any idea. Parul Embedded Engineer Einfochips Ltd

(Cross posted to theora-dev@xiph.org and ffmpeg-devel@mplayerhq.hu) I am working towards adding Theora encoding support to libavcodec in FFmpeg. I am doing this by simply calling libtheora from libavcodec. I am at the point where I can execute: "./ffmpeg -v 100 -i test.wmv -f avi -an -vcodec theora -b 1000000 -y test.avi" I get some whirring and an output file written. My calls to

Hi All, I think this may be off topic, but since it's through centos 5.2, I'm not sure. Here is what I would like to do: I have created a web page for family to log into and view clips of my new niece. My camera saves these clips in mpeg4 format. What I would like to do is have the web clients click on the link and have either the clip pop up a save dialog or even better, start

The licensing issue is still a mess, although they hope to make it at least coherent "real soon now". Use at your own risk. BTW, there is no MP4. The equivalent audio codec is the Dolby AAC.
