Can't download YouTube DASH video / utdated avconf

[andoruB]

I'm using Debian Sid, and up until a week ago, youtube-dl worked just fine, but now I can't download DASH videos. This is what I get:

WARNING: Your copy of avconv is outdated, update avconv to version 10-0 or newer if you encounter any errors.

After which I just get a non-dash video, which never goes above 720p30fps.
Is there a way to fix this, considering that I have the latest version that comes with this distribution?

Post the full output of youtube-dl when run with --verbose option.

Whoops, sorry about that:

This warning was introduced long time ago not a week ago. The only way is to update to version suggested or later.

There's the warning about avconv being outdated, as I mentioned at the beginning of the thread...
