1982907 - wpt reftest /css/css-sizing/aspect-ratio/replaced-element-003.html fails on new android 14 emulator - width(2) is invalid

Status: NEW

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

Description

https://treeherder.mozilla.org/jobs?repo=try&tier=1%2C2%2C3&revision=fdea14904f15d8fe3a01e1277a1ad60054bf5e8e&test_paths=css%2Fcss-sizing%2Faspect-ratio

the test:

• /css/css-sizing/aspect-ratio/replaced-element-003.html

generates a black square inside a green square, but the reference image doesn't have the black square.

Comment 1

[Daniel Holbert [:dholbert]]

The black square here is a <video> element which is solid green -- here's the video (note that its dimensions are extremely small, 2px-by-2px -- it's scaled up in the test): https://wpt.live/css/css-sizing/aspect-ratio/support/2x2-green.webm

If it's rendering black, that implies that we're failing to play the video for some reason. --> Reclassifying to Audio/Video: Playback.

Attachment: (the video file)

Comment 3

Attachment: testcase 1

Here's what-might-be a reduced testcase -- just a <video> element pointing at a bugzilla-hosted copy of the 2x2 green webm video file.

Presumably this renders with a black square instead of a green square on an affected Android 14 environment...

(In reply to Daniel Holbert [:dholbert] from comment #3)

Presumably this renders with a black square instead of a green square on an affected Android 14 environment...

Huh -- not exactly what I was expecting, but perhaps the same bug -- this testcase renders as a fully blank page for me in Nightly on my own Pixel phones (with Android 16). In Chrome on the same device -- and Firefox/Chrome on Desktop -- this renders with a green square.

Comment 5

[Daniel Holbert [:dholbert]]

DevTools shows this error when I load the testcase in Nightly on Android:

Media resource https://bug1982907.bmoattachments.org/attachment.cgi?id=9507186 could not be decoded. attachment.cgi

[Daniel Holbert [:dholbert]]

Not a recent regression; I can repro the issue in Nightly 2022-01-01 (v97) on the same Pixel 6a device.

Comment 7

[Daniel Holbert [:dholbert]]

Reproduces in gve (GeckoView Example App), too -- the testcase is blank.

Loading it in debug gve and checking logcat, I noticed this diagnostic output which might be useful:

Looks like this LollipopAsyncCodec.java file was added (a long time ago)by jolin in bug 1361679 -- jolin, maybe you could take a look here, or suggest someone who could? Looks like this extremely small webm file is failing to get properly handled there.

Attachment: logcat output from around when I loaded the testcase (filtered for "codec")

Here's a bit more logcat output from when I loaded the testcase on my Pixel 6a.

Comment 9

[Daniel Holbert [:dholbert]]

Aha, elsewhere in the context in the logcat (if I stop filtering for "codec" to look a bit more around) I see this:

08-14 11:59:24.503   952  1039 E VdecCommonParamIntf: [SizeSetter] width(2) is invalid
08-14 11:59:24.503   952  1039 E VdecCommonParamIntf: [SizeSetter] height(2) is invalid

No idea what VdecCommonParamIntf is, but apparently it's treating the 2x2 video size here as being invalid.

Thank you for all the analysis!
