Hello, Some years back I tried to use example_encoder.c with mkfifo FIFO buffers to encode content as it was being decoded by mplayer. This deadlocks, because to do this you need two FIFOs (one for decompressed audio and one for video) that mplayer alternates writing output to, and that encoder_example similarly alternates reading chunks of audi...

...vorbis (yes, there really is a mount command.) ./configure as usual compile vorbis.c in winamp directory with gcc -c link the dll with gcc --shared vorbis.o pathtolibvorbis.a pathtovorbisfile.a put the dll in the winamp plugins directory as in_vorbis.dll It seems to work. A song I encoded with the example_encoder (actually I used a script I listed in a previous message to call the encoder) plays fine. Weird rate (151 Kbps). Title is "Song encoded with example_encoder.c" or something of that nature. Other than that it's ok. Now if I could only find the freeamp and xmms plugins. Even if they...

...1 release. As part of that release, the program will offer the ability to play (for review purposes) both WAV and OGG files. I have both the decoder and playback code working but I have one final issue to resolve: finding the play time for the Vorbis bitstream that is being played back. I used the example_encode and example_decode code as the initial basis for my code model (but it has really changes a bunch since I started the project <grin>). Anyway, can someone inform me how I can get this information from the file using the OGG, VORBIS or VORBISENC DLL interfaces? I'd rather not add any new...

This message appeared in my inbox over the weekend. A useful idea although I have not reviewed the code. Might someone on the list (or the original author) be interested in running with it?

...Live webcam view of me at work' -g 'Webcam' -n 'Basil at work' aalimraan.hidayahonline.net 8000 ***secret*** /basil-at-work.ogv As you can see from that, the stream is 640x480 at 15 fps. I capture it with ffmpeg, convert it to a 4:2:0 YUV4MPEG2 stream, which I then pipe to the example_encoder bundled with libtheora. I am encoding the stream to 150 kbps (150/8 = 18.75 kB/s). I am NOT doing any audio encoding, since I'm at work, so that does save me some bits. Take a look at the video and see what you think. I'll try to keep it on for the duration of my stay at work today....

Hello. I'm a theora newbie... I see it accept video frames in some differents YUV formats. How theora manage them internally? I mean: if i encode the same video twice, first time encoding it with YUV444 packets and then with YUV420, will second video be smaller than first (due to subsampling...)? Or theora compress them in the same way? Thanks in advance, A. F.

Hi. I've put up some docs related to my first encounter with the vorbis source code at http://surf.chimie.uqam.ca/~kruus/vorbis/encoder/index.html It documents a newbie's first look and [serious] attempts to trace through examples/example_encoder.c . Don't laugh too hard! Even though the docs are quite un-doc-like, I've stopped working on them indefinitely, since Monty announced a forthcoming vorbisenc module which will probably invalidate whole sections of that particular web-doc. >From that doc, most of the links take you...

Hay! Has anyone come across these errors using valgrind for the oggenc tool or the encoder_example.c: ==13108== Invalid read of size 4 ==13108== at 0x4155734: _vp_offset_and_mix (in /usr/local/lib/libvorbis.so.0.4.1) ==13108==

Hello! I'm trying to use ffmpeg2theora to encode raw (.yuv) files in I420 format (just frames, no headers at all), but failed to find corresponding input format. Is there any documentation of supported formats for ffmpeg2theora? Or maybe there is another command-line tool for Windows to encode raw video using Theora algorithm? Thank you for help! Alexander.

...with PAL DVDs, except minus the telecine/pulldown stuff. However, I find that the audio is out by about one second per minue of video. The further into the video I play back, the more the audio gets ahead of the video. This indicates the detected frame rate, 23.976, is too low. If I force the example_encoder to use a frame rate near 24.34 (without adjusting any of its inputs), it's much closer to being correct. However it's almost impossible to get it exactly right. By the end of the movie there will always be a delay unless I go through a ridiculously long period of trial and error. Sev...

Updated again... theora works and seeks properly (not to keyframe) in WMP 9 and 10. You can encode from a bunch of onew input types like RGB32, RGB24, IYUV etc. And fixed a bug that was stopping the filters being used in a activeX control in an IE browser. www.illiminable.com/ogg/ Enjoy, Zen.
