> It is a live TV Streaming site and the VOD remains for 7 days.

Then you’d probably have better luck downloading the VOD episodes when they 
become available, since in a VOD stream, segments don’t “expire” and the master 
playlist stays constant unlike a live “event” type stream. Unless you were 
already doing that? If you were, the problem might be something else.

> Download speed: 7.84
> Upload speed: 0.61

I mean honestly it does seem like it would be unbearable but that’s just 
because I’m spoiled. The download speed is around what you would get with a 
dedicated t2 circuit, I don’t think it’s considered too bad compared to the 
global average and encoding houses take that into account when delivering for 
web streams. 

But what’s more relevant is the speed you get when you’re downloading the 
actual stream, I assume the test was done on a different server, the speeds you 
get when you’re connected to the server with the media segments will be 
different. I don’t know what the CDN of niconico is like, but how far you are 
away from Japan might affect it a lot.

Your connection speeds shouldn’t even matter if you download a VOD stream 
(apart from the time it takes), the streaming service might still invalidate 
the URLs after a while, but usually not while you still have an open 
connection. If you can post the output of 
% ffmpeg -loglevel trace -i "m3u8 master playlist url" -c copy -bsf:a 
aac_adtstoasc “example.mp4”
We’d know more.
Try to post the output of the command you run when you post to this list in 
general, it includes a lot of relevant information.
