Hi All, Should anyone be looking for one, here's a DirectShow-based command-line transcoder for Theora: http://www.eddiana.com/?totheora.html It can do basic video transcoding, as well as scale video, watermark video with a graphic, grab frame stills, capture from video sources, and perform a couple color transformations.

[theora] Windows command-line transcoder for Theora
That's a huge deal right there. That's the first tool I've seen for Windows to "easily" create Theora steams without needing FFMPEG, which isn't legally distributable in the US due to patent laws. With such a tool brings the possibility of legally freeing video from patent encumbered formats without having to first violate patent law to do so -- as long as you have a DirectShow codec for the source format (for which many legal versions exist, and in many cases ship with Windows). I'm going to try to contact the author of this, and see if I can convince him/her to use a proper Free Software license rather than the vauge "/Use of this software is strictly 'at your own risk'. You are welcome to use this version of the toTheora encoder in both free and commercial applications/." statement. I'll also request they post the source code, which doesn't presently seem to appear on the site. If such goals are attained, I'll probably create a PYGTK GUI for it, and bundle it in one of the next releases of our FreedomSampler disc.

With a bit of care when manipulating 4:2:0 YUV frames, where all the offsets should be multiples of 2. Thanks for this cool program, BTW. -- Lino Mastrodomenico
