A note about the CHANGELOG

Hello 👋 and thank you for contributing to Gradio!

All pull requests must update the change log located in CHANGELOG.md, unless the pull request is labeled with the "no-changelog-update" label.

Please add a brief summary of the change to the Upcoming Release > Full Changelog section of the CHANGELOG.md file and include a link to the PR (formatted in markdown) and a link to your github profile (if you like). For example, "* Added a cool new feature by [@myusername](link-to-your-github-profile) in [PR 11111](https://github.com/gradio-app/gradio/pull/11111)".

If you would like to elaborate on your change further, feel free to include a longer explanation in the other sections. If you would like an image/gif/video showcasing your feature, it may be best to edit the CHANGELOG file using the GitHub web UI since that lets you upload files directly via drag-and-drop.

Thanks @or25! PR looks good to me. Would you able to add a quick unit test? I think we can add it to test/test_components in TestFile.test_component_functions(). Basically, we'd want to ensure that the processing produces a file that is 0-seeked.

Hi @or25 would you be able to make the updates requested? Or would you like a hand in making these changes?

[abidlabs]

Hi @or25 we can lend a hand to get this over the finish line.
