Description of your issue, suggested solution and other information

If I run youtube-dl on a host in the US to download geo-restricted content like http://www.cwtv.com/shows/penn-teller-fool-us/you-dirty-rathead/?play=0c8763f4-6dfc-42c2-86af-02e9fd078334, it works fine. If I set up a SOCKS proxy and use --proxy socks5://127.0.0.1:11111/, it fails. I assume this is because youtube-dl calls ffmpeg, but does not instruct ffmpeg to use the proxy.

This is confusing. Either youtube-dl should pass proxy information to subcommands, or, if youtube-dl was called with the --proxy option and a subcommand does not support using a SOCKS proxy, youtube-dl should abort with an informative error message.

[yan12125]

if youtube-dl was called with the --proxy option and a subcommand does not support using a SOCKS proxy, youtube-dl should abort with an informative error message.

Seems ffmpeg does not support SOCKS5 at all, is it? It's a good idea.

[yan12125]

By the way, could you try to install python3-crypto and then run youtube-dl with --hls-prefer-native?

[yan12125]

Requested to ffmpeg at http://trac.ffmpeg.org/ticket/5776.

[scfc]

I successfully tried --hls-prefer-native, and for the URL mentioned I actually prefer it :-) because the resulting file shrinks from 1.5 GByte to 598 MByte without any noticeable reduction in quality.

[yan12125]

I've added a warning if SOCKS is used with ffmpeg. I didn't raise an error as some SOCKS proxies may also work as HTTP proxies.

[aeroxy]

Hi, for macOS users what should we do to enable --hls-prefer-native flag? brew install python3-crypto does not install python3-crypto (no package found).

[yan12125]

I remember Homebrew doesn't provide Python packages. Try to install it with pip; e.g. pip install crypto --user

[remitamine]

just a note, pycryptodome might be faster in the decryption as it does support AES-NI(not included in the latest stable version of pycrypto).

[aeroxy]

@yan12125 maybe you mean pip3 install crypto --user? Which python does youtube-dl uses by default? Python or Python3?

[aeroxy]

@remitamine so I guess I can use pip3 install cryptodom --user?

[yan12125]

Which python does youtube-dl uses by default? Python or Python3?

That depends. You can check the version from youtube-dl -v

pip3 install cryptodome --user should work, too.

[aeroxy]

@yan12125 looks like it uses Python version 2.7.10 - Darwin-17.2.0-x86_64-i386-64bit, so the follow up question is, can I change the default Python and if not is there a cryptodome for python 2?

[aeroxy]

Also it looks like when I uses pip I would just get pip: command not found...

[aeroxy]

I do have pip3 however...not sure wtf is going on with macOS these days.

[dwarf007]

For me the following worked:
pip install pycryptodome

Don't forget to source you ~/.bashrc or ~/.zshrc afterwards..
