certificate issue casting youtube

[willzeng]

Hi there! Thanks so much for this project!

I'm able to cast_site successfully but casting returns the following error. For example when I run the README example:

$ catt cast "https://www.youtube.com/watch?v=dQw4w9WgXcQ"
ERROR: Unable to download webpage: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)> (caused by URLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1056)')))
Error: Remote resource not found.

Some details:

• Operating System: macOS 10.14.2
• catt was installed with pip3

I tracked this error down as something that has also occured in youtube-dl [github issue]. I separately installed youtube-dl and got the same certificate error and then added the suggested workaround (adding the flag --no-check-certificate to the youtube-dl command) which then worked to download the video. Adding this in case it helps in some way.

Ah, this appears to be an issue with youtube-dl. Just pass the youtube-dl option to catt with catt cast -y and it should work.

Would it be possible to get an example commandline? I've tried every variant I can think of and can't get catt to accept/pass through this option.

For example,
catt -d "Office Home" cast --ytdl-option --no-check-certificate <url>
seems like it should work but gives:

Error: Invalid value for '-y' / '--ytdl-option': --no-check-certificate is not a valid key/value pair.

and trying to "fake it" with things like "--no-check-certificate=1" doesn't work (but doesn't give the same error, either).

Stumped as to how to format unary flags through -y in catt!

@benmargolin You need to use youtube-dls internal option names. This really should be in the readme.

catt -d "Office Home" cast -y "nocheckcertificate=true" <url>

Good call, I've added that. Thanks to both of you!
