Are there any specific requirements to enable "fast-start" progressive download with webm and ogg codecs?

Solution

Due to the way they are constructed, WebM (Matroska) and Ogg files do not have any fast-start remuxing requirements to make them suitable for progressive downloading.

Problem

I know that with `mp4`, the `moov atom` must be placed at the beginning of the file to enable progressive downloading. That can be done by enabling "faststart" when creating the file. I'm curious if there are any similar requirements when dealing with `webm` or `ogg` files, or are they "progressive download ready" by default?
