I need to download a video from foxford.ru.
I am using the command:

ffmpeg -i http://.../playlist.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4

Everything is downloaded, but the download time leaves much to be desired: 105 minutes (The most broadcast was 145 minutes). Now the question is: how can I speed up the download? Use streams? It's not because of the internet, because. My speed is 30 Mbps (3.75 Mbps). And all because it downloads in chunks (ts files).
Apparently they are using React.

Here's another piece:

<video class="video-react-video" preload="auto" src="blob:https://v3.foxford.ru/7e238b72-58b2-4910-a97c-4a41edf2ad23"><source src="https://storage.netology-group.services/api/v1/buckets/hls.webinar.foxford.ru/sets/58469/objects/master.m3u8?access_token=eyJhbGciOiJFUzI1NiIsInR5cCI6IkpXVCJ9.eyJhdWQiOiJmb3hmb3JkLnJ1IiwiZXhwIjoxNTU1NDA0MDA3LCJpc3MiOiJtZWRpYS1pZHAuZm94Zm9yZC5ydSIsInN1YiI6IjgwNTMzYTFjLWYwZDQtNDQ0Zi1hZWMyLWY5ZmVmOThiMmNhNCJ9.JaZeZTIiPBI7MBFUXQ9oiyXuj7ocXLf4XOPUFSSRzD4Iv7gikoQRI9Wc-lHpc3JOplNDokDU8OiAymYGGvK1kQ" type="application/x-mpegURL"></video>

And I still do not understand: do they then save in mp4?
