Back in the day I had a cursory glance at AVS. Out of curiosity I decided to add AVSS format support to NihAV. Despite it looking like an obscure format nobody has ever heard of, it’s well-documented. Under the name of Intel DVI (you know, Digital Video Interactive—mostly remembered for DVI ADPCM under the name IMA ADPCM).
Anyway, I’ve managed to locate just one sample containing single RTV2.1 stream so I was curious how it fares.
Well, it turned out to be the standard Indeo 2 format but for some reason actual image being down-sampled compared to what the headers claim (160×100 instead of 320×200). Nothing much to say but it was still curious to see that system from the past.
