theora - May 2010 - Windows command-line transcoder for Theora

Hi All,

Should anyone be looking for one, here's a DirectShow-based command-line 
transcoder for Theora:

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.

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.

Another useful feature may be cropping, to get rid of the annoying
black borders on some videos. 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.
