Expected Behavior

• Smooth Scene Transitions:

  • When a transition is initiated, whether via the transition button, Stream Deck, or mouse, the transition should execute seamlessly without delays or interruptions.

• Responsive Transition Controls:

  • Transition Button: The transition button should visually indicate when a transition is in progress and return to its default state once the transition is complete.

  • Stream Deck Integration: Actions triggered through Companion on the Stream Deck, such as "Cut" or "Fade," should consistently initiate the corresponding transitions without fail.

  • Mouse Interaction: Clicking the transition button within OBS using the mouse should reliably start the transition process each time.

  • T-Bar Functionality: The T-bar should respond immediately to user adjustments, allowing for smooth manual control over transition progress.

• Consistent Performance:

  • Users should be able to perform multiple transitions in succession without encountering unresponsiveness or the need for workarounds like switching scenes.

• Error-Free Operation:

  • Transitions should complete without getting stuck in an intermediate state, ensuring that all controls remain functional throughout the streaming session.

Current Behavior

1. Intermittent Transition Issues:

   • Occasionally, during scene transitions, the transition state becomes stuck.
   • This occurs roughly every 10 minutes during live streaming sessions where cameras are being cut every 4 seconds.

2. Unresponsive Transition Controls:

   • Transition Button:

     • The transition button in the middle appears to remain pressed and does not initiate the transition.

   • Stream Deck:

     • When using Companion, clicking the "Cut" (or "Fade," or any other) action multiple times has no effect; transitions do not occur.

   • Mouse Interaction:

     • Clicking the transition button within OBS using the mouse does nothing.

   • T-Bar Movement:

     • Attempting to move the T-bar has no impact; the transition does not proceed.

3. Temporary Fix:

   • The only workaround to resolve this issue is to switch to a different scene.
   • After doing so, transitions function normally until the problem recurs.

4. Summary:

   • Occasionally, OBS gets stuck in a transition state where the transition button remains pressed and becomes unresponsive.
   • Both Stream Deck and mouse inputs fail to initiate transitions, and the T-bar cannot be moved.
   • Switching to a different scene temporarily resolves the issue.

Steps to Reproduce

1. Launch OBS:

   • Open the OBS Studio application on your computer.

2. Set Up Multiple Scenes:

   • Ensure you have at least two scenes configured (e.g., "Scene A" and "Scene B").
   • Add necessary sources to each scene to facilitate clear transitions (e.g., camera feeds, images).

3. Configure Transition Settings:

   • Navigate to the "Scene Transitions" section.
   • Select your preferred transition type (e.g., "Fade," "Cut," etc.).
   • Adjust the transition duration and type as needed.

4. Integrate Companion:

   • Ensure Companion is installed and properly configured on your computer.
   • Link Companion with OBS to manage transition controls.
   • Use Companion to send changes to transition duration and type, ensuring that these settings are actively modified during the session.

5. Integrate Stream Deck (If Applicable):

   • Connect your Stream Deck to the computer.
   • Use Companion or relevant software to map transition actions (e.g., "Cut," "Fade") to Stream Deck buttons.

6. Initiate Multiple Transitions:

   • Begin transitioning between "Scene A" and "Scene B" using one of the following methods:
     • Transition Button: Click the transition button in OBS.
     • Stream Deck: Press the mapped transition button on the Stream Deck.
     • Mouse Interaction: Click the transition button within the OBS interface using your mouse.
     • Companion Commands: Send transition commands via Companion to initiate transitions.

7. Perform Rapid or Repetitive Transitions:

   • Execute several transitions in quick succession (e.g., 5-10 times) to increase the likelihood of triggering the bug.
   • During this process, actively send changes to transition duration and type using Companion to test if these actions contribute to the issue.

8. Observe for Unresponsiveness:

   • After a few successful transitions, monitor the transition controls:
     • Transition Button: Check if it remains visually pressed and unresponsive.
     • Stream Deck Actions: Attempt to trigger transitions via the Stream Deck and note any lack of response.
     • Mouse Interaction: Click the OBS transition button and observe if it initiates a transition.
     • T-Bar Movement: Try adjusting the T-bar slider and verify if it affects the transition.

9. Attempt to Resolve the Issue:

   • When unresponsiveness is detected, try the following:
     • Stream Deck: Press transition buttons multiple times.
     • Mouse: Click the OBS transition button repeatedly.
     • T-Bar: Move the T-bar slider to initiate a transition.
     • Companion: Send transition commands via Companion again.
   • Note that these actions do not resolve the issue.

10. Apply Temporary Fix:

    • Switch to a different scene (e.g., change from "Scene A" to "Scene B").
    • Verify if transition controls become responsive again.

11. Repeat to Confirm Intermittency:

    • Continue performing transitions to confirm that the issue recurs intermittently (e.g., every few transitions).

Anything else we should know?

I was doing it older version too.
