html: Support selecting <media> element source from children by tharkum · Pull Request #39717 · servo/servo

tharkum · 2025-10-08T13:13:42Z

Follow the HTML implemetation and support selection of the 'media' element loading source from 'source' children elements with validation processing over their 'media/src/type' attributes.

See https://html.spec.whatwg.org/multipage/#concept-media-load-algorithm

To handle loading with multiple 'source' children was introduced source children pointer to track the remaining unprocessed 'source' elements after the resource selection algorithm was invoked.

Testing: Changes in the following tests
with improvements:

html/semantics/embedded-content/media-elements/loading-the-media-resource/*
webgl/tests/conformance/textures/misc/texture-video-transparent.html

with regressions (after enabled 'source' type attribute validation):

content-security-policy/media-src/media-src*
mixed-content/gen/top*audio|video-tag*
resource-timing/initiator-type/*

Fixes: #21481
Fixes: #34127

tharkum · 2025-10-08T13:17:24Z

JFYI < Almost all following tests were fixed, except the next:

resource-selection-currentSrc.html (not implemented MediaSource in Servo)
resource-selection-invoke-in-sync-event.html (buggy test itself)
resource-selection-source-media-env-change.html (buggy WindowProxy in Servo)

Really great work! Thanks for all the new spec text comments.

Follow the HTML implemetation and support selection of the 'media' element loading source from 'source' children elements with validation processing over their 'media/src/type' attributes. See https://html.spec.whatwg.org/multipage/#concept-media-load-algorithm To handle loading with multiple 'source' children was introduced source children pointer to track the remaining unprocessed 'source' elements after the resource selection algorithm was invoked. Testing: Changes in the following tests with improvements: - html/semantics/embedded-content/media-elements/loading-the-media-resource/* - webgl/tests/conformance/textures/misc/texture-video-transparent.html with regressions (after enabled 'source' type attribute validation): - content-security-policy/media-src/media-src* - mixed-content/gen/top*audio|video-tag* - resource-timing/initiator-type/* Fixes: servo#21481 Fixes: servo#34127 Signed-off-by: Andrei Volykhin <[email protected]>

Fixed error handling between network and media engine failures
Add tests with regressions (filled the new issues for servo/media - see above)
