1984681 - Videos with horizontal/vertical flip metadata are not rendered correctly

Status: NEW

(Core :: Audio/Video: Playback, defect, P2)

Description

[Jamie Nicol [:jnicol]]

The WebGPU CTS has some video resources which have vertical or horizontal flip metadata. They were produced using ffmpeg's -display_hflip and -display_vflip arguments. The readme describes how they were generated in depth.

The videos (along with the source png they are generated from are available here: https://github.com/gpuweb/cts/tree/02f6385d66880b112321acfb479b6734e23ae340/src/resources

If you open the hflip or vflip videos directly in firefox then the yellow square is in the top-left corner, matching the source image. ie the flip has not been applied. In Chrome, it is correctly flipped.

Added to Media Planning review. Likely H1 2026, but we might be able to get to this sooner.
