Crash when trying to extract audio

[jftuga]

I am using the Windows youtube-dl.exe 2015.04.03 from the web site.

If I run:
youtube-dl.exe --extract-audio --audio-format mp3 -k "https://www.youtube.com/watch?v=AN_iBKvR3fY"

The .mp4 is saved to the hard drive, but then I get this error:

I downloaded the youtube-dl python source and then ran:
main.py --extract-audio --audio-format mp3 -k "https://www.youtube.com/watch?v=AN_iBKvR3fY"

I now see this error:

How can I fix this?

Thanks,

ffmpeg was not installed.
It would be nice if the program reported this problem instead of crashing.
After I installed ffmpeg, everything worked as expected.

Thanks for the report, the bug will be fixed in the next version and it will suggest installing the program.
