After running "youtube-dl -U", I get "Your copy of avconv is outdated update avconv to version 10-0 or newer if you encounter any errors."

You can try updating avconv (old versions may not support some of the formats used by YouTube). If you want to disable merging DASH formats, you can add -f best to your configuration file.

If youtube-dl doesn't work, we'll need the output you get with the --verbose option for debugging the problem

[hub2git]

What is the recommended way to proceed? Update anconv or disable merging dash formats? This ubuntuforum thread (http://ubuntuforums.org/showthread.php?t=2277302) makes me think that choosing well is crucial.

if you want to get resolutions higher that 1280p you'll have to update avconv, if you don't mind which resolution you get you can disable merging.

[hub2git]

hi, jamieMF. thanks for your comment. I don't need resolutions higher than 1280p.

[hub2git]

so i guess i'm fine with the other method.

How exactly do I update avconv?

[yan12125]

What's your operating system? If you're using ubuntu, apt-get is your friend.

yan,
Linux Mint. I already have avconv, so how does apt-get help?

[yan12125]

I'm not familiar with Linux MInt, while I think it's similar to Ubuntu. The following commands may help:

sudo apt-get update
sudo apt-get upgrade

How to update avconv is out of the scope of youtube-dl. A Linux Mint forum should give you more information on it.
