Question

i want to download a mp4 video from here: https://speedvideo.net/embed-2992oz2oqv79.html. Now this url provides 3 mp4 videos (and a php file whose obviously i don't care):each of them has a different quality and so a different filesize. youtube-dl is unable to tell me anything about these videos:

So i can't select the best quality video to download and i have to download all the videos (succesfully):

So,it seems that at the download moment youtube-dl knows the size of the videos.
Now, the google chrome browser extension "videoDownloadHelper" can tell me the filesize of the videos:

Here is the detail of the best of the 3 videos:

youtube-dl does not provide me any informations about size or approximated size:

One possible solution: I could consult videodownloadhelper and download the heaviest file in terms of MegaByte and it works:

youtube-dl --min-filesize 700M "https://speedvideo.net/embed-2992oz2oqv79.html"

but it's a cumbersome solution. Is there another solution? thank you by the way, youtube-dl is an amazing application!
