[FFmpeg-user] [httpproxy] Protocol not on whitelist

[Yicai Xu]

Hi,

I am trying to play Youtube videos with ffmpeg. However, I found ffmpeg
might not play the video if I am behind a proxy.

For example, if I try playing a youtube video on a PC behind a proxy by
doing

ffmpeg -i "http://www.youtube.com/watch?v=dQw4w9WgXcQ" -vcodec copy -acodec
copy out.mkv

in my terminal. Then I will got the following output:

http://www.youtube.com/watch?v=dQw4w9WgXcQ: Invalid argument

However, if I use a computer without any proxy settings, then ffmpeg
would play the video normally.

Do you have the same problem? Am i doing something wrong? Should the
httpproxy protocol be put into the whitelist?

Thanks!

Best,

Erdos
