Tweak Filter with Default Settings Crashes Nvencc64

[wwaag76]

If the Tweak filter is added with no changes to settings, Nvencc64 crashes. Even the slightest change, e.g. "brightness=.000001", leads to a successful render. Here's the command line I've used.

nvencc64 -i --codec hevc --cqp 28 --preset default --vpp-tweak brightness=0.00,contrast=1.00,gamma=1.00,saturation=1.00,hue=0.00,swapuv=false --audio-source :codec=aac;bitrate=128;delay=44 -o .mp4

Here's the output from a simpliefied command line with no audio. No log is generated.

The default setting does not do anything (no changes is done by the filter), so please remove the whole "--vpp-tweak" option there, and you'll be fine.

I might fix the crush in the future.

The crush when running vpp-tweak with no effect can be avoided in NVEnc 7.73.
