Description

I've tried to format this URL using formats provided in the yandexvideo.py, but all of them either result in this error. Additionally, using the URL I get from my browser (https://yandex.ru/efir?stream_id=4362958a44d495cb82b231578d19c3c0) does download a video, but only the low quality 5 second preview, not the full video. I've verified this behaviour on multiple videos on the Yandex site.

I'm downloading from the US west coast. Chrome reports a DOMContentLoaded time of 1.56 seconds and a load time of 2.40 seconds for me, and the video plays back perfectly fine in the browser. The error takes about that same amount of time to show up (time says the command executes for 1.04 seconds when it gets a 408 error), unless the timeout is very short I wouldn't expect it to be hitting it.

Thank you in advance!
