Description
Is there an existing issue for this?
- I have searched the existing issues and checked the recent builds/commits
What would your feature do ?
Currently, a custom node author can use image_upload in the input spec and an upload button will be added to the node. This feature would allow for something like:
{"file_upload": True, "accept_filetypes" : ["video/webm", "video/mp4", "video/mkv"]}
Which would behave the same as the image_upload widget, but instead change the accept when invoking the system fil picker to match with the accept_filetypes field. The custom node can determine how to handle the uploaded file and what the output type is. The frontend and server would just be responsible for uploading the file to the server and then providing the filename (same as image_upload).
Proposed workflow
- Custom node author sets the
file_uploadoption in theINPUT_TYPESof a custom node for some input - Custom node author uses second option
accept_filetypes(or similar) to specify the filetypes - An upload button is added to the node, which opens file picker and accepts the given filetypes.
- The widget value of the input is just the filename of the uploaded file
