I just updated to 29.0.2 and I the error in the title shows up whether I'm using NVENC or x.264. I'm running a GTX 1080, and I updated GPU drivers and that didn't help. Log posted below. The only definite errors I can see are failure to load AMD encoder and decklink drivers, which makes sense. Other than that, the only things that stand out to me are an error with NVVideoEffects.dll, and encoder ID mf_h264_nvenc not found. I don't know if the first one matters, and the second one definitely sticks out to me, but it seems to load NVENC fine higher up in the log, and like I said x.264 doesn't work either.
