Thank you :-) I'm not sure about the support of the FFMPEG DJGPP Port of networking, it would be cool if we could play youtube/ or any stream channel .

Thanks for testing on bare-metal, Curious about your [VideoMode] settings on DUGLPLAY.CFG which worked, I maybe have to bring the list of available video modes for selection on new config dialog.
I think this caused by a buggy VBIOS, using another screen maybe solve the problem.

yes, smoothing do just merge RGB of each pixel with RGB of pixels around it. but fine tuned with 16bpp RGB565 to avoid getting greener.

It's useful particularly for low res video to increase quality, as you can see on the screenshot the left/before right/after smooth
but it can be improved further for better downsizing of videos, as DUGL Viewer did on the past, so it's kind of Soft anti-aliased rendering, relying the on the fast assembly implementation to be only 30% to 70% solwer, but depends !

Yes seeking is within easy goals, I'm just playing with FFMPEG to see how to do it. I already struggled for a week with FFMPEG to successfully implement fast frames dropping ..
I need then to improve DUGL SB16 driver/then rely on VSBHDA to bring me sound :-)
