tool dedicated to analyze theora stream
Hi! Is thear any tool dedicated to analyze theora stream, like H264Visa for H.264? Or any other tool helpfull for analyze? I want use it to analyze products of my developing hardware implementation of theora encoder. Thanks all! -------------- next part -------------- An HTML attachment was scrubbed...

Compiling theora
I have tried following the Theora Micro How-to http://www.xiph.org/archives/theora-dev/200209/0092.html I have been able to: * download * compile * encode But decoding/playing does not work. I get: $ examples/player_example < fiatlux.theora.ogg sh: examples/player_example: No such file or directory See http://ole.tange.dk/projekter/theora/ for more precise information. <p>/Ole --

Using Theora Micro-HOWTO
Okay, thanks to some stubbornness on my part and helpfulness on the part of people on this mailing list, I got the Ogg Theora alpha compiled up and installed and running. Yesterday, I went to the Prelinger archives (the public-domain video archive at www.archive.com) to find a high-quality original to re-encode as a test. The encoder worked just fine, and playback as well, and I thought I'd

theora test suite
some of you may find this helpful: I've uploaded a short (5 second) raw clip in yuv4mpeg format, associated audio, and batch files to exercise the encoder & decoder examples. In addition I've included the file as compressed (test.ogg), and a longer version as well to test playback sync. Notes: to use MPlayer with the -vo yuv4mpeg option, you need to get the latest release and compile

Ogg Theora files player
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).

Theora performance
Hi list, I just came across this site: http://web.mit.edu/xiphmont/Public/theora/demo.html I was wondering are these issues being addressed or will be addressed before the 1.0 release? Theora is like the only open sourced free code people can use, i will be nice if it performs close to other libs. please keep up the good work! -------------- next part -------------- An HTML attachment was

Theora encoder performance
I'm evaluating some video codecs for a online conference system. I'm encoding images (640x480) from a webcam. I've been playing around with theora and xvid. First of all, using theora, the decoded image looks strange: http://integrasoft.ro/~mgliga/theora/comparison.png <http://integrasoft.ro/%7Emgliga/theora/comparison.png>.

NHW Image codec - YCbCr color space
Hello, Just a very quick message to let you know that I have definitely switched to YCbCr color space as YCbCr is better, more precision.I have updated my demo page: http://nhwcodec.blogspot.com/ . Any comment on this new version from the Xiph Community would be very appreciated, as I am developing alone (it really took some time to switch to YCbCr...).Also (as it was said), I am not totally

theora encoder reordering, order of puting data from DCT 8x8 blocks to huffman compressor, and puting result of huffman compressor to buffer bitstream memory
Good day! I'm creating HDL IP CORE (for using in FPGA) for theora encoder (now only I-frames). I don't undestand one moment. Now i develop such stages: 1. From RBG(byer) to YCbCr converter 2. DCT processing (8x8 pixels blocks) 3. Quantizator of DCT coeff. 4. Zig-Zag of quantized DCT coeff. and now i have uresolved last stage of compression - how i must send 8x8 blocks to huffman

will there be theora_decode_RGBout() ?
hi folks! i would like to know whether there will be some function to decode to some plain 24 bit RGB buffer in the future. i think this feature is sometimes important, especially when using different surface layers, or when modifying the buffer in realtime. if this feature will definitely not be, could someone tell me how i can convert to some RGB buffer in realtime? i already tried different

How to do Theora playback efficiently ?
Dear theora developer community, currently I'm working on a simple Theora player for Windows. But the code in the player_example.c seems not to have the performance of other implementations like the Direct Show filters by illuminate. In the example player, all important things are done in one thread: decoding the next vorbis or theora packet(s) and reading from the physical stream (+ split

idct8x8 C version in libtheora1.1 release
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

example sources
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

Beginner Hurdles
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
