Encoding doesn't start - "missing input"

[kocane]

Different source filter.
FFVideoSource uses ffindex files.
LWLibavSource (in Hybrid) only is used with index files in memory.
If the source is on a network drive it can slow down things,...

Could imagine it would be slow on a network drive. I just threw the file onto my SSD instead of the HDD and while it's faster it still takes a while. 

Is that just how it is with HuffYUV or can it be adjusted?

btw. the missing input stuff in the debug output is from the job processing which checked whether another subjob could be started, but wasn't since the output of the encoding wasn't there.

Is that a misconfiguration on my part?
