Expected Behavior

I have some video sources with mp4 files in it. These sources are not visible. They can be made visible by channel-points. So far so good.

But: I found out, if you use "Fade" as a "Show Transition" and "Hide Transition", they can be only be played ONCE. After making the source visible, it plays once, after that, the source gets invisible (by streamer.bot or by hand), but if you make it visible again, it never plays again - until i restart OBS Studio.

This worked before Version 30, as far a I remember. Since 30.x it does'nt work anymore.

Current Behavior

The video is only played once

Steps to Reproduce

1. Add a new video source (it's a short 3.8 Secs. MP4 Clip)
2. Check all boxes except "Loop"
3. Right click the source, choose show Transition, set it to Fade. choose Hide Transition, set it to Fade
4. Hide the source
5. Make the source visible
6. Hide the source
7. Make the source visible
8. It won't play anymore
   ...

Anything else we should know?

No response

No source file or test is named. First reproduce the repeated show/hide sequence on OBS Studio 30.2.0-beta3 and inspect the provided log URL, then trace the Fade show/hide transition lifecycle. Done means a non-looping video source replays the Fade transition after being hidden and shown repeatedly.
