libshout 2.2 has just been released. It's a fairly minor update: * Speex support (this is why it's 2.2 instead of 2.1.1) * Theora timing fix * Double-free bug, response parser bug on failed login fixed. It's at http://www.icecast.org/download.php

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.

...it with the Theora and Speex DirectShow-filters. For audio, this filter graph plays fine: http://www.huitl.de/mic-speexenc-speexdec-out.png. The video part is problematic. Please have a look at http://www.huitl.de/cam-theoraenc-theoradec-out.png. 1. The webcam provides the color formats RGB24, I420 and IYUV. The Theora encode filter only accepts YV12, so I can't just connect the webcam capture pin with theora's yv12-in. 2. The "Color Space Converter" can't do the conversion to YV12. 3. I found that the ffdshow raw video filter should be able to do this conversion (al...

"... we need a baseline to work from - one standard format that (if all else fails) everything can fall back to. This doesn?t need to be the most complex format, or the most advertised format, or even the format with the most companies involved in its creation. All it needs to do is to be available, everywhere. The codec in the frame for this is Ogg Theora..." :)
