Encoding doesn't start - "missing input"

[Selur]

Is that a misconfiguration on my part?

No, that's a normal behaviour. Hybrid checks the sub-jobs and avoids starting those where the inputs are missing.

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

No clue, it's normal that the progress indication in Hybrid takes a bit since:
1. when LWLibavSource is used it still needs to index the file, it just keeps the index in memory and usually can start without having to index the whole file.
2. encoders usually request a bunch of frames (lookaheads) before they start encoding
3. Hybrid should only start showing a progress if the progress > 1%.
4. depending on the filters, an the order and amount in which they requires frames, especially the start can take a bit. (especially on hdds this will slow things down)
5. If anti virus or similar software are also trying to check the data all the above steps will be slowed.

Still the time to start seems unusually long, but I have not clue what's causing it on your system. If you think Hybrid is not starting checking the cpu usage is usually a good indicator,..
