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, I want to make a program to extract frame from a theora movie as images. I tried with the decoding example located at theora web site (dump_video.c. I use it to extract a frame as yuv image but when I try to convert it to ppm with yuvtoppm program i obtain a strange image ( see http://poux.be/tmp/file.ppm ). I think it's a problem with the byte order for yuv, but don't I don't

I'm going to try documenting the various sections as I figure them out, in order to help others who are trying to implement the Theora CODEC. I'll go back and document the stuff I've already done, but I'm starting at the loop filter limits because that is where I ran into my first uncertainties. I found where libtheora did its loop filter limit decoding, and printed out the

Today I've got first video clips made by the camera and compressed "on the fly" - 1280x1024x30fps. Image quality is far from perfect - I don't have yet any way to preview images, and a single acquisition still requires a bunch of commands. So I'm really close to have a camera that will be able to serve the Ogg/Theora streams, now but will it be possible to play it on a PC? I

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

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, I heard that Theora will be used on OLPC. Is anyone working on optimization for OLPC? Regards, Chih-Chung Chang

(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, Attached is my patch to add theora encoding to ffmpeg's libavcodec (by using libtheora). I am requesting help to fix the bug I mention below and am seeking general comments before I submit the patch properly. Files encoded using this encoder have a problem playing in VLC. The files will not play unless "Drop late frames" has been unticked in the advanced video settings.

Hi all, I tried to compile the theora source with VS2005. But it asked for the ogg library. error message is as follow. **************************************************************************** Error 1 fatal error C1083: Cannot open include file: 'ogg/ogg.h': No such file or directory c:\Documents and Settings\Manoj\Desktop\libtheora-1.0beta3\include\theora\codec.h 64 Error

the files produced by windows compile vs. Linux are indeed significantly different in size (about 140K vs. 160) However I'm not convinced all the default parameters are set the same way in the two example files. This needs to be verified to see if there really is a bug, or can the two versions produce byte-equal output streams? <p> ___ Dan Miller (++,) Founder, On2 Technologies

All, I've done a new alpha release of the libtheora reference implementation. This is mostly build fixes from the alpha6 release; I'd failed to enable the new MMX asm by default, and the x86 asm code did a relocation that caused problems on SELinux. You can get it in the usual place: http://downloads.xiph.org/releases/theora/libtheora-1.0alpha7.tar.bz2

Hi, in the past two days I wrote Python bindings to libtheora: http://github.com/certik/python-theora Currently it can read any ogv file (that seems to work quite well) and also encode to ogv (this mostly works, but there are some subtle issues to be fixed, I suspect I still have some bug in the way I half the dimensions of the Cb and Cr planes, so when you read ogv and write ogv, the resulting

I apologize for what's surely a common question, but the Xiph archive-searcher seems broken, and all my other searches have come up dry. Anyway, my question is: Are there any Theora binaries available for Visual Studio.NET? Alternatively, how do I build Theora using Visual Studio.NET? I tried using "\win32\theora_static.dsp", but VS.NET claimed it was corrupt and couldn't

I have an old conferencing app that uses theora and I'm building it for win64. libthora 1.1 builds just fine, but libtheora 1.0 has errors related to assembly code when building for x64. I've tried using 1.1, but the video does not look right -- the clients all generate their own first 3 packets instead of sending them over the network since they assume they are all on the same version

The debian (unstable) libtheora and libogg packages are a little out of date. I was wondering if anybody had made their own packages for libogg-1.1.1 and libtheora-1.0alpha4. If not, I'll go ahead and package them up and put them up on my own debian repository or something, and let you guys know where to get them. But if somebody has already done that, let me know. thanks, Tim

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
