Hi Wolfgang!

Thank you for your feedback, this really helps a lot.

Yes, it is bilinear OpenGL scaling (in a linear color space).

Could you add an entry to the bugtracker at
https://savannah.nongnu.org/projects/bino/ ?
Such an option would be easy to add once someone finds a little free
time to do it. With a bug tracker entry, this idea will not be lost.

For presentations, you can also use the scripting mode
https://www.bino3d.org/doc/bino.html#Scripting
e.g. to show intro and outro "slides" or to automatically switch
content.

Yes, in theory if both streams contains key frames at the same
positions then seeking should behave identical, but sometimes
FFmpeg ends up at different frames. I'm not sure why, either. The only
safe way around this is to encode both views into a single stream, e.g.
in top/bottom or left/right form.

Again, if you add an entry for this in the bug tracker, I'm sure it
will be implemented once somebody finds the time.

Best regards,
