**Game Name?**
Skylanders: Trap Team (rev 1)
**Game ID?**
SK8E52
**MD5 Hash?**
1dd69ec30fc8fbb18cccd503ee721cb9
**What's the problem? Describe what went wrong.**
"Memory stride too small (0 < 1280)" is logged during prerendered videos. Also, fifologs of these videos don't play properly unless "immediately present XFB" is enabled.
**What steps will reproduce the problem?**
1. Start the game with the Video Backend log type enabled and the log level at Error or lower.
2. Observe the log; "Memory stride too small (0 < 1280)" will be spammed during the Activison and Toys for Bob videos.
**Is the issue present in the latest development version?**
Yes, 5.0-15105
**Is the issue present in the latest stable version?**
The log message itself doesn't show up in 5.0, but the fifolog playback issue does exist; however, XFB defaults to disabled in 5.0, and this issue only shows up when XFB is enabled (though it happens with both virtual and real XFB).
**What are your PC specifications?**
* CPU: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz, 2592 Mhz, 6 Core(s), 12 Logical Processor(s)
* GPU: NVIDIA GeForce GTX 1650 Ti
* Operating System: Windows 10.0.19042.1165
**Is there anything else that can help developers narrow down the issue?**
The "Memory stride too small" message should show up in 5.0, as it was added [before then](https://github.com/dolphin-emu/dolphin/commit/74b772c3be4a724c12094c08d26466fdbb4f841b)
This game uses Bink Video 2; it does exhibit video artifacts associated with that, but this issue happens even when those are fixed.
The video in question is `movies/tfb_logo_640x456.mov`, which the `file` command identifies as `Bink Video 2 rev.i, 640x448, 300 frames at rate 1/30, 1 audio track 14848Hz mono`. As this is a 30fps video but the game runs at 60fps, every other frame has no actual content. `BPMEM_MIPMAP_STRIDE` is set to 0 on those frames, while it's set to 0 instead of 0x28. All frames trigger an EFB copy with `Clear` and `Copy to XFB` enabled and mipmaps disabled.
