Intermittent visual bug, 1 frame glitch on stinger transitions #10

Closed flaeri closed 2 years ago

flaeri commented 3 years ago

Helping Lindenkron troubleshoot a strange issue, that ended up being plugin related, and it seems to track back to virtual-cam-filter.dll. I've confirmed it myself, and Lindenkron has as well.

Info

Win10 20H2 OBS 27 (release) Virtual Camera Filter 0.0.4.0 i7 8700, gtx 1070 Log: https://hastebin.com/dapekenama.yaml

Repro steps

  1. Install latest obs-vcam-filter
  2. Create a new scene collection
  3. The default scene (named scene) can be empty, shouldnt matter
  4. Add two new scenes (scene 2 and 3). Add contrasting color sources to them, like scene 2 = red and scene 3 = green
  5. Add a vcam filter to the first scene (default scene, named scene)
  6. Add a known good stinger with track matte
  7. Transition between "scene 2" and "scene 3", 1 to 30 times.

Every once in a while you will see 1 frame of the destination scene before the transition starts. More complexity may increase the frequency of this glitch occuring. This was the simples setup, with the least amounts of variables I could still repro the bug.

Removing the vcam filter will result in the glitch to no longer happening.

Closing, this was not a vcam-filter issue, it was just really good at triggering the underlying issue. My aplogies. ref: https://github.com/obsproject/obs-studio/issues/4886
