Yes, the Theora codec is based on VP3, which is an earlier version of ON2's VP6 codec. Theora is currently at its alpha 3 release, and is stable enough to have been used already for streaming live video from a number of conferences, and for encoding several videos that can be found at www.theora.org. Development has progressed to the point that the value of the codec can be seen. That

Are we interested, or ready for this? Andrew Seddon is offering to provide hardware to port Theora to the DSP Stamp. http://www.linuxdevices.com/news/NS4405077268.html John ---------- Forwarded Message ---------- Subject: RE: DSP stamp Date: Friday 29 October 2004 03:50 am From: "Andrew Seddon" <andrew.seddon@camsig.co.uk> To: "'John Kintree'"

As far as video playback is concerned, it seems to mostly come down to how the video is compressed - although Gnash (the open flash player) still has a ways to go to play flash media as well as the closed source flash players. For the Colingo activity and library, we've found it very difficult to find optimum settings for flash and instead have decided to go with Theora. We've managed to

I am going to improve theora codec with dynamically changing way. In this case we want to change compression parameters like video_q, sharpness when a keyframe is generated. When i set video quality parameter using cpi-> pb.info.quality in CommpressKeyFrame in encoder_toplevel it will not change dynamically. Can you please help me to do this. Wich function should i cange to achieve my

Speaking of portability and people more familiar with SDL: The reason we have two example players for theora is that monty wrote the original example around the OSS audio interface used on several free unix-like operating systems, which immediately excludes win32 and MacOS, even though it used SDL to display the frames. SDL also has audio support, and is quite widely ported. splayer replaces

I'm playing the "Honey" movie (both Honey-small and Honey-large) and I notice significant slowdown during periods of lots of motion (when the camera shakes, when the first man hops into bed, when people turn around and approach the camera, etc.). The audio plays smoothly all the time but when there is a lot of motion, the picture freezes and resumes when there's less motion.

Hello all, Very new to Theora so apologies if this sounds elementary ;-) I'm trying to integrate a simple theora video player in my engine. All I need is simple load/unload and play/stop functionality. I'd also like to be able to stream from disk or mem. Other than the API reference I haven't found any example code, e.g. the sources for theora_player_example. Are these available

Reviewers who have published comparisons of video codecs recently tend not to publish their source video clip, nor encoded video clips.? It might help promote theora if there was a link we could provide to a nice source clip, only one or two minutes long with a mix of action and talking head spots, with several versions of it compressed in theora format; maybe 250 kbps, 500 kbps, 750 kbps, 1 mbps,

Hello list, When I convert an yuv pixel into rgb using the recipies in http://www.fourcc.org/fccyvrgb.php I get an accurate color conversion but the contrast seems to be decreased. If i write, e.g., the pixel directly into an sdl yuv_overlay, I get a well-contrasted frame, however, if I convert the pixel to rgb and call SDL_MapRGB, I get a contrast-decreased frame. Thanks, Ribamar

Hi, Please could give me a hints how to get below header files, these are not available in my system. Am running player_example.c which is given in theora dump. Getting error that below files can't open. I checked in "C:\Program Files\Microsoft Visual Studio\VC98\Include" and these are not present. #include <unistd.h> #include <sys/soundcard.h> #include

just to let you know I posted a frontend to ffmpeg2theora and mencoder using the latest kommander. It's still in early developement but it'll get more feature with the time hopefully :) http://kde-apps.org/content/show.php?content=17831 Pat __________________________________ Do you Yahoo!?

Hey everyone, I just got Theora running on my Mac, and ran across several hurdles, that I was wondering if someone could help me with. I do a lot of tech support at work, and get the same questions over and over, so I tried skimming the archives but couldn't find the answers. Maybe these could go in a FAQ of some sort? These are fairly unavoidable issues that should probably be

hi all: i downloaded libtheora1.0.tar.gz from xiph.org, and when i compile it, such error message popped. i tried to run player_example.c under /libtheora_1.0/examples/. error message: ivysummer at ivysummer-desktop:~/??/libtheora-1.0/examples$ gcc -o player player_example.c /tmp/ccpyle3c.o: In function `buffer_data': player_example.c:(.text+0x15): undefined reference to

Hi My PC is Intel Pentium P4-HT, running Linux kernel 2.6.0-test10. I have the latest GNU automake/autoconf system.

Hello, I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP. I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip). When I compile player_example.c Visual Studio shows: fatal error

I am successfully able to build today's theora_cvs_snapshot under NetBSD/i386 1.6 with SDL disabled. (I haven't tested yet.) I was unable to build with SDL: player_example.c:52: sys/soundcard.h: No such file or directory I see the source says it is OSS-specific for now. This is what I did to make it build: --- work.rainier/theora/examples/player_example.c.orig Mon May 19 12:31:37

I posted a while back "complaining" about lack of a theora player on the iPhone. Porting the code for libtheora (and libogg/libvorbis) was (relatively) painless, and appears to be working. I'm up against a tougher challenge now... rendering the video! I tried using the brand-new SOC-funded SDL port to iphone to get the "player_example.c" code up and running, but ran into

When using the IDCT routines, the C version [ lib/idct.c: oc_idct8x8_c(ogg_int16_t _y[64],int _last_zzi)] in libtheora 1.1.1, the decoded image is garbled. Is it functionally equivalent to the MMX optimized version [lib/x86/mmxidct.c: oc_idct8x8_mmx(ogg_int16_t _y[64],int _last_zzi)] ? I used some of the Theora video files from here: http://wiki.xiph.org/index.php/List_of_Theora_videos for
