Error caused by KeyError('Ai',)

[LisanneG]

I've been using this gem for a long time, really love it but recently i tried to download a youtube video but it gives me an error
Sample code i used:

require 'youtube-dl.rb'
options_mp3 = {
extract_audio: true,
audio_format: "mp3",
output: '%(title)s.%(ext)s'
}
YoutubeDL.download "https://www.youtube.com/watch?v=HoVWmW0Zdmo", options_mp3

Error i got:

D:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/cocaine-0.5.8/lib/cocaine/command_line.rb:91:in `run': Command 'D:/Ruby22-x64/lib/ruby/gems/2.2.0/gems/youtube-dl.rb-0.3.1.2016.09.11.1/vendor/bin/youtube-dl --extract-audio --audio-format "mp3" --output "%(title)s.%(ext)s" --no-color --no-progress --print-json "https://www.youtube.com/watch?v=HoVWmW0Zdmo"' returned 1. Expected 0 (Cocaine::ExitStatusError)
Here is the command output: STDOUT:

Really hope the error will be fixed or i'll get a solutions because this gem is the only one I loved working with.

Sorry for the late reply. My guess is it's probably just a really old youtube-dl version. I haven't had the time to update or work on this gem in several months and definitely not enough time to build something to automate updating the vendor youtube-dl. New Years Resolution: Start pushing out more updates.

In the meantime manually install youtube-dl. As long as the exe is in your PATH this gem should detect it and use it instead of the vendor youtube-dl.

Thank you for the respond. I've been making my program in c# in the meantime which means i currently use the youtube-dl.exe. Either way I still really appreciate the gem, it has made my live easier for some months 👍
