Opencast embeds not responsive with “Original size” | Moodle 5.0.4 (Build: 20251208) | filter_opencast (v5.0-r2 | 2025080102)

[adnbes]

Hello,

we noticed that Opencast videos inserted via TinyMCE are not responsive when “Original size” is used. Setting “Custom size” to width/height = 0 makes them responsive but affects the editor preview.

Environment

• Moodle 5.0.4 (Build: 20251208)
• Editor: TinyMCE
• Plugin version, (filter_opencast | v5.0-r2 | 2025080102)

Steps

• Add “Text and media area.”
• Insert media → Opencast → select file.
• Choose “Original size” → Save.
• Save and return to course.

Actual

• Video is fixed-size, not responsive.

Expected

• Video should be responsive.

Hotfix applied
We temporarily forced width/height to 0 in text_filter.php:

// Original:
$width = self::get_attribute($match, 'width', '[0-9]+');
$height = self::get_attribute($match, 'height', '[0-9]+');

// Hotfix:
$width = 0;
$height = 0;

Could you confirm if this is a bug and if a fix is planned?
Thanks!
