[MAJOR BUG] Encoding finishes prematurely

[Lipomo]

1. Neither gpu encoding nor decoding is enabled by default.
2. afaik there is no decoder or encoder chip out which supports FFV1
3. so if your source is FFV1 then gpu decoding won't work. (since your target is FFV1 gpu encoding also is not an option)

Cu Selur

Got it.
