I am trying to polish the video upload process for my TinyMCE setup.
I have managed to get the videos to upload via my upload script (as opposed to uploading as a blob) by using the answer at https://stackoverflow.com/a/68182918
I would like to have a progress bar shown when uploading. Based on https://www.tiny.cloud/docs/tinymce/6/upload-images/#images_upload_handler I tried to add
xhr.upload.onprogress = function (e) {
progress(e.loaded / e.total * 100);
};
from within the file_picker_callback function, after the xhr.open('POST', '/your-endpoint'); line, but I just get errors that progress is not defined, because the progress callback does not get passed to file_picker_callback.
How can I show a progress bar (presumably one built in to TinyMCE) for the upload from file_picker_callback?
