Twitter video: output MP4 video url

[Kikobeats]

Hello,

I noted that the Twitte extractor is extracting the video URL after following an authorization flow. It is well expplained at this comment: #12726 (comment)

This workflow is reflected using verbose mode

However, the mp4 video URL is not present in the output if you use -g/--get-url:

or -j/--dump-json flag:

I suppose this is happening because under these flags the flow exited early, without evaluating the necessary code for extracting the real video url.

Could be possible to include the logic to output the mp4 URL properly?

No mp4 is available for this video.

@dstftw I don't understand, you are getting the mp4 video url because you download it, right? Just run the process under the rest of situations
