It's not really related to Gabest's RM DS filter.

rids3290.dll is now called dsreader.dll. Maybe I did not quite understand your question.. Helix producer still reads its source files via dshow on Windows, but it understands common YUV formats, like YV12, I420, YUY2 natively, so these VFW codecs are not used. Producer then simply tells dshow to provide the raw data without going via a decompressor.

I found good use for the I420 codec in particular when running some PSNR tests in Avisynth, because all my ITU test clips are in I420, and the I420 codec outputs YV12 when requested. Similarly, if you happen to have I420 files from capture or other sources, and want to compress to XviD or another codec that accepts YV12, just use "Fast recompress" in VirtualDub to avoid going via RGB.
