Video Not Supported about buffpy HOT 2 OPEN

The way of sending media[video][details][location] using Content-Type": "application/x-www-form-urlencoded actually works. My bad that I said it doesn't . I have tested it with an old video(ie whose id I already knew from the web version), it works.
But for new videos there is still some work to be done. It doesn't work if the video is not in their s3 bucket. So I have to figure out how to make a request to first put the video in their s3 bucket(rather than mine) and then get the generated video id just like how they do via web. I will keep posting my findings. Views welcome

It's actually 3 step process:

• GET on https://publish.buffer.com/rpc to get etag
• POST on https://buffer-media-uploads.s3.amazonaws.comto upload the video to s3 {s3_bucket_id}/{etag} with

key: {s3_bucket_id}/uploads/{1567502606048}-my-original-finename.mp4
Content-Type: video/mp4

• POST on /1/updates/{post_id}/update.json
  (here we use the etag as id and also construct video[detail][location] with it)
  with media json like this:

 {
       "progress":100,
        "uploaded":True,
        "uploading_type":"video",
        "video":{
            "title": "some titile",
            "id": etag,
            "details":{
                  "location": "https://buffer-media-uploads.s3.amazonaws.com/{s3_bucket_id}/{etag}/doesntmatter.mp4",
                  "transcoded_location": "https://buffer-media-uploads.s3.amazonaws.com/{s3_bucket_id}/{etag}/doesntmatter.mp4",
                  "file_size":6767009,
                   "duration":27,
                   "duration_millis":26611,
                   "width":480,
                   "height":270
             },
             "thumbnails":[
                   photo_link,
                   photo_link2
             ]
          }
}
