So I lied. I couldn't give this one up. I decided to use the tried & true opera
technique, discussed at great length here:
https://groups.google.com/g/video-downloadhelper-q-and-a/c/8V2cRB-bcK4
But there was no manifest, no file of type m3u8 in the Network Monitor (accessible via
F12). So I decided to just scroll through everything there in the hopes of seeing
something that might be a manifest. I can't say this was any sort of scientific process.
I guessed. Complete, wild-ass guess. What caught my eye was the entry of type x-mpegurl
I have highlighted in the first attached image. Hovering the mouse over that entry gives
the URL you can see in the image. You can copy the URL to the clipboard by clicking MB2
to pop up the context menu & copy it. Here's the URL, just for reference:
https://video.twimg.com/ext_tw_video/1460921632877334535/pu/pl/576x1008/byYLK1ZL1ZEwNY5P.m3u8?container=fmp4
I don't know if this URL varies from user to user, session to session, or if it stays
constant. In any case, I double clicked on that entry in the Network Monitor. It turned
out to be a manifest for a stream. Luck. Pure luck. I can't explain it. I had no idea
what would happen but I gave this URL to ffmpeg. It downloaded an MP4. It was the
video. VLC played it just fine, with both video & audio for the whole 33 seconds of it.
Doesn't do you any good unless you're willing to get totally geeky about it by learning
what there is to learn in that thread in this forum whose link I cite above. And I have
no idea how well this technique might generalize to other Twitter clips. But if you
really want this video, that's how to do it.
On another level, how can VDH do this without making the user resort to such extreme
measures? I can't say. Maybe this says something to Michel. What I've shown here is
that the information necessary to download this video is available. I don't know if this
means VDH can be updated to use the information.
Actually, on further investigating after I had already written the above, I did find a
master manifest, as you can see in the second attached image. That would have made this
a little more scientific. The URL I cite above appears in that manifest. Well, sort of
appears. The
https://video.twimg.com part of the URL is missing from the manifest. But
you can see that the master manifest & the 2 media manifests are found so you can get the
complete URL as I describe above.
