Hello everyone.
First, sorry for my bad english !

I want to download video from this url : bongngo.vn (this is a website in Vietnam). I use ffmpeg with command :
Code:
ffmpeg -y -i "http://117.103.204.131:1936/bongngovod2c/mp4:./464e590318a54e5da7a3d4123fbba175/53907980/Encoded/Movie/2014/5/30/24177_the-perks-of-being-a-wallflower-2012-1080p-bluray-dts-x264-d_480.mp4/playlist.m3u8?wowzasessionid=1149761109" -bsf:a aac_adtstoasc -c copy output.mp4
When I run, it seems fine, however about 2,3 minutes later, its stopped:

Code:
