Mirvio Downloader — Chrome store 1.1.0; tested 1.2.0 update

Direct files: MP4, WebM, MOV through Chrome. Real fixture downloads pass SHA-256 checks. Public MDN MP4 and JWPlayer MP4 paths passed earlier live tests.
Cloud: authenticated paid Mirvio plan, quota before work. Public Wistia and the VTurb v4 inline embed sample passed production tests on October 20, 2026. A public Vidalytics MPEG-TS HLS sample passed an earlier production test.
HLS: supported complete, unencrypted MPEG-TS and fragmented MP4 playlists, including matching separate audio. The deployed cloud worker passed a Mux sample. Finite HLS byte ranges and static DASH are supported in the cloud. Live streams, discontinuities and encrypted/DRM streams remain unsupported.
Page detection: accessible HTML video/source elements, same-origin frames, open shadow roots, public metadata and recognizable recent media requests. Cross-origin frames and closed shadow roots can prevent detection.
YouTube: excluded from this package and its cloud jobs. No hidden switch. App jobs cannot be imported.
No universal site support. Private, paywalled, DRM or sign-in-protected media is not supported. Expired URLs and source-host restrictions can cause failures.
Published Chrome Web Store version: 1.1.0. Version 1.2.0 passed production tests but awaits store submission.

The separate ZIP still needs Developer mode and Load unpacked.

Version 1.2: exposed public VTT/SRT subtitles; cloud MP4/WebM/MP3/GIF exports with trim times; supported quality/audio preferences. GIF is limited to 30 seconds and 480 pixels. All four export formats passed real production extension saves, hashes, and full decodes. Source quality and audio availability vary.
