Filesize not loaded properly...

[vraixen]

Version running
yt-dlp v2025.01.26

Describe the bug
Downloading a video on certain websites causes the indicator of the filesize to display "0 b" even though the file has been downloaded.
I have seen that the filesize when gets properly displayed get displayed even before the file finished downloading. this make me think that probably on some websites the size doesn't get parsed properly.

To Reproduce
Steps to reproduce the behavior:
1 Downoaded a video normally. (for example this websites cause the issue "https://video.lefigaro.fr/figaro/video/appel-entre-trump-et-poutine-pekin-contente-du-dialogue-entre-les-etats-unis-et-la-russie/")
2 You will see that the file size will be 0 b. for exmaple on sites like youtube this issue doesn't appear.
