How can I tell if a file is a valid video stream using RVideo ?
8 février 2012, par fenecI am trying to see if a file has a valid video stream using the RVideo library :
read_file.rb :
require 'rubygems'
require 'rvideo'
file_path="/mnt/glusterfs/video/2012/02/04/2012-02-04 1000 CSPAN United Nations Security Council Meeting (337711).mp4"
puts file_path
file = RVideo::Inspector.new(:file => file_path)I get this error :
rbennacer@services:~$ ruby read_file.rb
/mnt/glusterfs/video/2012/02/04/2012-02-04 1000 CSPAN United Nations Security Council Meeting (337711).mp4
sh: Syntax error: "(" unexpectedEven when I put a backslash before each space character and parenthesis character, I am getting that error.
