Optimizing download speed with ffmpeg

[peace2]

Hello
I want to download some videos using this command line:

ffmpeg -i "the link" -c copy test.ts

Is there a way to increase download speed?
I have read other posts where the other user suggested these commands:

livestreamer "hls://http://50.7.69.186:1935/edge/_definst_/fzasab6vz02yuf7/chunklist.m3u8?wowzasessionid=1419914830" best -o video.ts

livestreamer --hls-segment-threads 10 "hls://http://50.7.69.186:1935/edge/_definst_/fzasab6vz02yuf7/chunklist.m3u8?wowzasessionid=1419914830" best -o video.ts

none of them worked for me.
Any help will be really appreciated.

Than you.
