what i found with in this above response
the size is available where signature variable is in that direct_url and that is downloadable

other wise size is not there.

[somik123]

The first video has an encrypted signature.

Set 'enable_youtube_decipher_signature' => true, in your config file, chmod cache folder so it is writable. then it'll work fine.

[Nasdav]

@somik123 , setting 'enable_youtube_decipher_signature' => true
induce this error :
The first argument should be either a string or an integer
Should I set 1 instead?

[somik123]

@Nasdav both 1 and true will work. Php says it in the same way.
