Current Behavior

Stream is encoded and decoded (selkies-core.js:92 Processing 1 pending chunks for stripe Y=0), as shown in logs, but does not show in NVENC with pixelflux utilized.

Doesn't happen always, but does happen sometimes.

Expected Behavior

Likely need to ensure that the keyframe was received and request a keyframe to the remote when the decoding is with issues or the screen doesn't show.

Steps To Reproduce

Randomly happens in NVENC w/ pixelflux.

Environment

- How docker service was installed:

Docker creation

  -e DEV_MODE=selkies-dashboard \
  -e PUID=1000 \
  -e PGID=1000 \
  -v $(pwd):/config/src \
  -p 3001:3001 linuxserver/chromium bash

I cannot replicate this, I have also not had any other reports. We might have just fixed this along the line without knowing.
