Hello, in case somebody wants to test Theora without compilation, feel free to use konvalo.org's setup. It includes mplayer with theora from svn 2004-09-21 with Wim Taymans' mmx-patches from August 2004 applied (there are mplayer and mplayer.theora-mmx, the latter with decoder mmx-patches from VP3HoSwiYO) and a theora-encoder script (a bit slower than ffmpeg2theora as it runs several

Hello, ffmpeg2theora (with encoder mmx patches) is available on konvalo.org. You can run it on Linux (2.6.x), FreeBSD (5.x) and NetBSD (2.x) on Intel x86. ffmpeg2theora may be considered the recommended Theora encoder. The author of the program is Jan Gerber @ v2v.cc Those of you who already use Konvalo.org do not need to do anything, the program is in your PATH. Otherwise see

There is bit space in Bitstream Header to put Huffman codes in. However, This space can take only 80 kinds of Huffman code set. And This space is divded into DC Huffman code set and AC Huffman set, and There are only 16 choices in each DC and AC Huffman code set. If we want to use this space, we find out best(or proper) performance 80 frequency counts(Huffman code sets) from tens thousands of

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

Folks, the packets I want to place in an ogg stream are concatenations of two hunks of memory. Rather than memcopy() them into one then pass them to libogg, I patched framing.c to accept iovecs. The unified diff is 80 lines, minus the OS-specific stuff for defining struct ogg_iovec_t - pretty trivial. Is there any interest in it? Or is libogg frozen while all efforts are concentrated on

Hello, An old theme just came up on the Wikipedia mailing list again : Wikipedia strongly encourages[1] using theora encoding, strongly enough that I don't think we currently host any other video encodings...[2] however, most users know how to make and edit and play mpegs, and find theora hard to work with. http://mail.wikimedia.org/pipermail/wikipedia-l/2005-March/038244.html Perhaps the

I tried encoding http://home.tange.dk/theora/stream.dump with http://home.tange.dk/theora/optag-dvd 4. From that I got http://home.tange.dk/theora/dvd-4.theora.ogg. mplayer stream.dump works fine, but when playing the theora encoded file on my 2 GHz computer both mplayer and xine take 85% of my CPU while X takes the remaining 15% (i.e. 0% idle time) and the playback is no way near smooth.

Hi, I am creating a new ogg stream for theatrical/stage/disco lighting and am having trouble encoding my comment header with the following code in _tp_writelsbint function, it does not write the second byte to the ogg buffer. I am using windows and have created a new win32 library project with visual studio and added my code, what do i have to do to get the function working? Is there a project

Hi, When I built libogg2 for testing the new vorbose utility, gcc 2.96 stumbled over a portion from stream.c that mixes variable declarations with statements. The patch below fixes this. -Carsten.

Hi all, I tried to compile theora on my windows, i installed Msys with mingw32. First I compiled ogg it seem have no problems for that, then I tried to compile theora and first run the ./configure with the good path for the ogg library. But I saw that the ./configure stopped because my version of ogg must be newer than 1.1 but I have the 1.1.3 ! This is my error : checking for oggpackB_read... no

hi all I found that in the revision 10730 of the libogg2 library it is impossible to do bitpacking. this is due to the implementation of the (at least) two functions oggpack_writeinit() and oggpack_readinit(). they both take an (oggpack_buffer *) as an argument and immediately erase all it's contents: void oggpack_readinit(oggpack_buffer *b,ogg_reference *r){ memset(b,0,sizeof(*b));

Just out of curiosity, did someone write a tool that dumps in a human-readable form the audio content of a vorbis file ? -- Giuliano. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

I've been implementing Ogg FLAC support in an editor I'm working on, and I must admit to being frustrated by the lack of support for the codec on the Ogg layer... and this is more than lacking granulepos. The codec's I've worked with, and my own (Writ), use Page 0 for general information about the codec. Specifically, the samplerate, bitrate, quality, number of channels, all

Hi, I am thinking about making a small tool. After reading about patents and mp3 I choose another format. OGG seems best. I was wondering if I can edit the OGG files and adjust the volume, to create a Fade-in and Fade-out. The tool I need makes configurable timed fade-ins and fade-outs of the volume of my OGG files. And if someone knows good python libaries for OGG I would like to hear
