Self hosted videos fail with “No video with supported format…”

    Hi there,
    When I use the Gutenberg video block to embed a self-hosted video, sometimes it works fine at first and then the video url is replaced with a weird blob url like “blob:https://xyz.com/3120dcc9-7892-42d3-90f2-88c933e9b441”.
    I get the following message in the backend: “can’t access property “get”, n.headers is undefined”
    and this one in the frontend: “No video with supported format and MIME type found”.
    and the video disappears from the media library.
    I have tried that on a test website without any plugin and with a builtin theme, the result is the same (with .mp4 videos).
    Any help appreciated.

  • The “blob” URL is just a temporary URL to let you see a preview of the video in the editor while it’s uploading. After a successful upload, this is supposed to be automatically replaced with the correct URL.

    So either you’re not allowing the video to finish uploading, or it’s not even starting the upload at all. (Note that if the video file size is large, it might take quite a while to upload — from a few minutes to even hours, depending on the size and on your internet speed.)

    Do you see the video in the media library? And does the video in the media library have the full, correct URL? Does the video play when you open the video URL directly in the browser?

    If the answer to all the above is “YES”, then simply remove the video you inserted in the editor, and insert it again from the media library.

    If answered NO to any of the above questions, you’ll need to re-upload the video. Instead of doing so from the editor, you can do the upload from the media library, and then go back to the editor to insert the already uploaded video.

    Good luck!
