Bink video cannot play with "Overlay Fill Screen with Aspect Ratio" in UE 5.7.1 Standalone mode

In UE 5.7.1, Bink videos fail to play in Standalone mode when using “Overlay Fill Screen with Aspect Ratio”.

​

The video plays correctly in the Editor (PIE), and the same content also works when using Render To Texture. However, in Standalone Game mode, only the debug message (“Seek & Play”) appears while the video itself does not render.

This behavior does not occur in UE 5.4, where both playback methods work as expected.

Steps to Reproduce

  1. Download and open the attached test project
  2. Open Content/Maps/BinkTest.umap
  3. Play in Editor (PIE) and walk into each Trigger Box
    1. Overlay Fill Screen with Aspect Ratio → Works correctly
    2. Render To Texture → Works correctly
    3. Both methods play the Bink video and display the “Seek & Play” debug message
  4. Play using Standalone Game
    1. Overlay Fill Screen with Aspect Ratio → Only the “Seek & Play” debug message appears, but the video does not render
    2. Render To Texture → The Bink video plays correctly and shows the “Seek & Play” debug message

Hello,

Thanks for reporting this issue. This issue was likely occurring because in standalone mode Bink was trying to draw directly to the backbuffer but not getting a valid texture. We have a fix for this in CL#50170076 Bink: Fix for GetRenderTargetTexture on the BackBuffer not returning valid backbuffer at runtime. That fix is going to be in 5.8 and not currently slated for a 5.7.x release.
