[youtube][bug][2016.03.27] bestvideo/bestaudio can vary on same link

[ghost]

Hey.

I recently noticed that a command like this:
youtube-dl -f 'bestvideo+bestaudio'
can vary on what formats get downloaded on the same link.

I can't provide any logs since it seems to be random when it occurs based on which dash manifest returned an error.

My guess is, it's related to this code segment.
https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/youtube.py#L1629-L1664

The version is 2016.03.27.

FYI, you can do something like this:
https://github.com/rg3/youtube-dl/blob/master/youtube_dl/extractor/youtube.py#L1629-L1664

It's a lot easier..

Didn't knew that, thanks.
Changed it.

It may vary. YouTube doesn't roll out all the formats immediately when the video appears but instead formats appear as they format encoding finishes or some other criteria.

I might should have added, that I wasn't talking about new videos.
This problem occurred with videos which were uploaded more than a week ago.

It could be..

Anyway, if there is anything YouTube modifies when processing requests, it's on the server-side, I don't think that any script or tool or program running on the client can do something about it.
