Uncaught ssl.CertificateError

[olf42]

Hi,

I ran into an uncaught ssl.CertificateError today, as I tried to download a video from ZDF-Mediathek. It seems that ZDF is using a bad certificate, but youtube-dl crashes badly.

I entered:

youtube-dl "http://www.zdf.de/ZDFmediathek#/beitrag/video/2696938/Hacker,-Freaks-und-Funktion%C3%A4re"

(It may not work from outside germany. Furthermore in a few days the movie is likely to be removed due to (de)publication guidelines)

I end up with:

[ZDF] 2696938: Downloading video info
[ZDF] 2696938: Downloading SMIL file
[ZDF] 2696938: Downloading f4m manifest
[ZDF] 2696938: Downloading m3u8 information
[ZDF] 2696938: Downloading m3u8 information

Followed by this traceback:

I use archlinux, and youtube-dl version

1. You are using an outdated version of youtube-dl. Read our FAQ if you have troubles updating.
2. They use misconfigured certificates for some URLs (those are skipped in latter versions of youtube-dl).

If you are not willing to update unsecure solution is to use --no-check-certificate.

Thank you for the quick response.
