Subject: [youtube] Fall back to header if playlist title is not available
X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=c91778f8c0ba120378cb806f694fdc3f94a5634c;p=youtube-dl

[youtube] Fall back to header if playlist title is not available

Sometimes (in about 10% of requests), the og:title is missing for a weird reason.
See #2170 for an example
