This assumes you have ffmpeg installed on your machine already...
To download try this...
Code:
ffmpeg -i "http://frdlzsmb.cdnviet.com/psczntp/_definst_/screen_red.360p.stream/playlist.m3u8" -vcodec copy -acodec copy -bsf:a aac_adtstoasc Viet-Output2.mp4
To play in ffplay...try this
Code:
ffplay -i "http://frdlzsmb.cdnviet.com/psczntp/_definst_/screen_red.360p.stream/playlist.m3u8"
Cheers!
P.S. to play in vlc, I would copy and paste the m3u8 link into vlc, but for some reason it's not working for me
