1868451 - Incorrect hardware video scale on FireTV Stick

Status: RESOLVED FIXED

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

Description

[jhnsmth1052]

Steps to reproduce:

Play any video in Firefox/GeckoView on a Fire TV.

Actual results:

All videos are scaled incorrectly on the Fire TV Stick 4K (2nd Gen). They are "zoomed in" on the top left corner. Setting gfx.webrender.software=true fixes this issue. This bug appears to be related to these two:

I have tested a patch that applies the fix for Mediatek 6735 and Kirin 980 devices to Mediatek 8696 devices as well and it appears to work.

Attachment: Bug 1868451 - Override SurfaceTexture transform on mt8696.

The patch for Bug 1784109 fixes incorrect video scaling due to the system
providing an incorrect transform matrix on Mediatek 6735 devices. This
patch applies this workaround to Mediatek 8696 devices as well.
