I tried that initially, but it seems to only accept direct y4m/yuv input, even in x265 builds that are compiled with AVS/VPY/whatever support and accept it otherwise as a single input.

Unless I'm doing something wrong, which is very likely.

I want to think there was some way to pipe those in? Ala

Code:
ffmpeg.exe -i foo.mov -f yuv4mpegpipe - | x265.exe - --y4m
Although I don't see an obvious way to translate that to the --abr-ladder syntax.

If there's a hard requirement for uncompressed input of multiple simultaneous streams, the read speed of the storage media could become a bottleneck.
