Two things:

1) about valgor:

2) Nobody uses Theora anymore.
But if you want to use it anyway, I recommend that you encode with ffmpeg2theora and then remux the video into an .AVI file with ffmpeg. Theora doesn't have B-frames so the remux will work well even with the VfW interface.

I really wonder if there's a single use case for Theora today, even for legacy applications.

Did it ever have hardware support? Even VP8 got some hardware support, so that would be a much better choice if you need a royalty free codec on some old hardware.

Just fyi: when I tested theora long time ago, I used Theora Win32 Binary like this:

encoder_example -o output.ogg -v 3 -a 5 input.wav input.yuv

which generated (theora+vorbis).ogg iirc. It was (perhaps still is) also possible for VLC to write theora+vorbis.ogg and even theora+flac.ogg. And back then, there was Helix Player too, supporting Theora out-of-box.

But that's history, we better move on... although, it would have been fantastic if Theora had become a patent-free codec with x264-like quality.

The big challenge is always that lots of great techniques are patented. AV1 and MPEG-5 EVC are two ways to approach that, but in the end VVC with its patented techniques remains the most technically promising forthcoming codec.

The link doesn't work.

Were you asking a question or making a statement?

Well, Theora is an (old, deprecated) video codec and Vorbis is an (old, deprecated) audio codec, so I'm not sure of your point. You can't convert or use players for on to the other.
