similar to: Does Theora support scalable decoding?

With the newly released SVC (Scalable Video Coding) of H264 I was wondering if Ogg/Theora has any plans of following suit or are there plans to implement a better solution? the closest to SVC I have seen at Xiph is bitrate peeling but that never happened and to date does not seem to be in any TODO list. thanks, -------------- next part -------------- An HTML attachment was scrubbed...

As far as my very limited knowledge goes the Theora video format is less complex than H.264 (High Profile for example). Please correct me if I am wrong. Does this also mean that I can expect that decoding a Theora stream is easier/faster to decode than a H.264 stream with comparable quality / or comparable bitrate? My (very practical) tests do show that it's easier for my computer to

Hello people My name is Felipe and I sent a proposal to the Google Summer of Code that the goal is to get a FPGA embeded system decoding Theora Streams in real-time. It was accepted and the mentor is the Ralph Giles. The proposal can be viewd here: http://atlas.lsc.ic.unicamp.br/~portavales/wp-content/uploads/2006/05/soc_proposal.txt There is also a presentation with a better division of the

Note: I'm resending this message because it seems it didn't get through to the list for some reason. I also updated the date from 14th to 13th per request Mike and derf's request. Original message as follows: So, we haven't hold one of those monthly meetings in ages. Monty mentioned he would like to schedule a Theora-specific meeting to establish a proper roadmap to get out of

Hi, Attached is a patch against 1.0alpha7 to speed up Theora decoding. It is about 15~20% faster in my test. It consists of following things: * MMX loop filter based on Rudolf Marek's patch in http://lists.xiph.org/pipermail/theora-dev/2005-August/002838.html * MMX IDCT based on Rudolf Marek's patch in http://lists.xiph.org/pipermail/theora-dev/2005-July/002816.html and the code in

Hi all I'm currently writing a decoder for Ogg Theora videos. Since I'd like to show the progress of the video, I need to know how to read the current (with granulepos?) and total number of frames from the Theora header. I didn't find an appropriate field in the header specifications for the total number. Thanks for helping me out with this. Regards, Stefan

Hi, I'm attempting to decode Theora videos on a PowerPC running a Linux 2.6.19 kernel. The version of GCC I'm cross-compiling from is 3.4.4. The software versions I'm running are: libogg-1.1.3 libpng-1.2.20 libtheora-1.0beta1 libvorbis-1.2.0 These are all the latest I was able to download. Here's a back trace I got while running "dump_video" under

Hello, My name is Robin Mar?n and I have some questions about the Theora Codec/project... First of all I don't know if this is the right place to ask but I haven't found any Xiph/Theora forum or something similar... I don't even know if this is the right way of "posting" in mailists... But anyway... I discovered Theora just like a moth ago when the 1st alpha of Thusnelda

We are scheduling another meeting to discuss Theora matters. One of these was planned just a while ago, but it pretty much didn't happen. So let's make this one happen. Anyone interested in Theora or video technologies is welcome to attend. The place is #xiphmeet at irc.freenode.net, this Tuesday at 14:00 UTC. If you don't know when 14:00 UTC is, go here[1] for conversion into

Sorry this is being set so on top of schedule, but it's the date Ralph and derf have confirmed as be able to attend. This will be (hopefully) the final meeting to set the release date for non-RC 1.0, as well as find out what the core developer team is up to. An agenda may be found here[1]. Feel free to fill it with matters deemed worthy of discussion. You may review what was already

I am trying to write a media player in c# which will be able to play .ogg video files which contain Theora video and Vorbis audio streams. Currently I am using LibOgg and LibTheora (via a SWIG generated wrapper). This currently is able to decode the video and output it to the screen. I would like to use LibVorbis to decode the audio stream. Looking at the documentation it looks like I have to use

Hi, last week's thread about getting closer to a release fizzled out. The mailing list discussion and the TheoraTodo wiki item suggest the following are required for release: 1. freeze the theora logical bitstream format 2. complete the reference implementation tools 3. stablize the libtheora API 4. complete the documentation I'd like to suggest this as

Theora can encode video with several quality parameters. So when that encoded video is decoding it should be looked at quality value. For a single video, decoder get first frame quality value for all video frame or decoder get each quality value for each frame? -- Asanka Dilruk Department of Computer Science and Eng.

I am trying to write a sample app that uses Theora for encoding/decoding a network video stream. Unfortunately, I keep running into this error: Run-Time Check Failure #3 - The variable 'MVect' is being used without being defined. It always happens on decryption, line 467 in decode.c. The issue is that CodingMethod is equal to 5 (CODE_GOLDENFRAME), which doesn't initialize the

I try to merge VP3's mmx decoder into theora. http://kyoto.cool.ne.jp/vp3/developers/theora-alpha3-MMXd-src.zip You can see the change by searching the keyword "_UsingMMX_" in all lib folder's file. From VP3???YO vp3@go8.enjoy.ne.jp

Fellow Theora users, For long you have waited for the stable release of the official implementation of everyone's favorite video format. Well, this is its Release Candidate, and you are hereby invited to play around with it as much as you want. Here's what's new since beta3: - Merge x86 assembly for forward DCT from Thusnelda branch. - Update 32 bit MMX with loop filter fix. -

Hi all, This may sound like a weird problem, but I am trying to create a DirectShow graph (using the Theora DirectShow filters from http://www.illiminable.com/ogg/) where I have a video source, which is connected to the Theora encoder, which is then connected to a Theora decoder. The problem is that this doesn't seem to work, those filters refuse to connect to each other. Now obviously
