NVEnc Preview

[Dan64]

That's interesting. I compared your version with mine, and the only significant difference is that you generate a command string using: ' '.join(command), while I was using the join only in log_message, and in Popen I was using the array version of command. Theoretically both the approaches should produce the same behavior, but in practice only your approach is working (despite the documentation).
Great ! now there is the possibility to introduce the preview of NVEnc in Hybrid. What do you think ?
