tar: Error opening archive: Unrecognized archive format

[TigerHemeng]

When the script runs to "curl http://www.ffmpeg.org/releases/$SOURCE.tar.bz2 | tar xj
|| exit 1", the terminal occurred an error: tar: Error opening archive: Unrecognized archive format.

How to fix it

It looks like they stopped serving http protocol. Just change http to https and it works.
