Creation Date / Uploaders Date

[rg3]

Was: http://bitbucket.org/rg3/youtube-dl/issue/159/

Is it possible to include the uploaders Date to the filename. The epoch option is the download date?

[rg3]

No, sorry, the epoch is taken from the current time in your computer. I'll think about the upload date.

I'd also like to see this feature -- for instance when downloading a series of videos which aren't otherwise numbered.

Originally by "XulChris":

Hi, please add this feature. I'm downloading a user's channel which has hundreds of videos and I would like them sorted in upload order. I would like to be able to use -o to specify a date/time format like YYYYMMDDHHMMSS

Thanks.

I will have a look at implementing this. Only the upload date is specified not the time. I will make sure though. Regarding date format, it is possible to implement using strftime() notation. eg. '%Y%m%d' for YYYYMMDD, but the output format sequence needs to contain a name eg %(upldate)s, else parsing it will become unnecessarily complicated. So perhaps if we set it to YYYYMMDD as the default it should be fine for chronological ordering?

[rg3]

If they upload a video the same day, the order may not be preserved, but it may be fine for some users.

Edit: BTW, yes, in that case the reasonable option is YYYYMMDD. The template text could be "uploaddate", no need to shorten it.

I will only be adding this to YoutubeIE for the time being. I will set the uploaddate to u'NA' for the other IEs.

[rg3]

Ok. That's a good start. As you said first, this is a general template parameter, so it should either be added to all IEs or set to NA. Ideally, the date would be extracted from any site that provides the information.

[rg3]

I had to rewrite your code for "uploaddate" because it failed in my tests. By the way, I renamed the template parameter to "upload_date" after noticing there was already a "player_url" FD parameter, so as to be consistent. Anyway, the problem is now solved.

Hi, sorry I'm only replying now. I made a silly mistake in the code I commited when I refactored. Really sorry about that! Please view the comments I've made on the lines in your commit 138b11f (138b11f#commitcomment-201370). No probs with "upload_date" :-)

[rg3]

I've read the comments. You don't see dates in other languages because youtube-dl sets the language in YouTube prior to downloading the first video. That's why you see the line "[youtube] Setting language". Your method would appear to work here. I'll fully review it one of these days and may revert back to it, if just because it's better if I get rid of that month table.

[v01d-cypher]

Hehehe ok cool. I will rebase against the current master and make sure the code is correct so it's easier for you to review. I will do it on another branch in my repo perhaps. We can also generate a list of locale based month names like so :

month_names = [datetime.date(2001, i+1, 1).strftime('%B') for i in range(12)]

[rg3]

That would be great. Just redo your changes (yes, using another branch to implement the feature is a great idea). I'll pull your changes when they are ready. I'll also notify you of any problems while testing it, so you can fix the code before I merge it. There's no need to generate the month names if parsing the date with strptime works.

Looking forward to your pull request.

It would be great if I could obtain this uploadDate info with a flag instead of having to download the video for its filename or parse the json with an external tool.
