Thanks.

Hi,
Put this piece of code into "The script read additional properties RSS" settings section of the podcast:

Code: Select all

var
  sYoutube, sVideoID: string;
  xYoutube: TXMLDocument;

function GetYoutubeDate(const sValue: string): variant;
  begin
    if trim(sValue) <> '' then Result := Copy(sValue, 9, 2) + '.' + Copy(sValue, 6, 2) + '.' + Copy(sValue, 1, 4) + ' ' + Copy(sValue, 12, 5)
    else Result := Now;
  end;

begin
  if WmsRegExMatch('watch\?v=(.*)&', mpFilePath, sVideoID) and (sVideoID <> '') then begin
    sYoutube := WmsDownloadURL('http://gdata.youtube.com/feeds/api/videos/' + sVideoID + '?fields=published');
    xYoutube := TXMLDocument.Create;
    try
      xYoutube.LoadFromString(sYoutube);
      PodcastItem.Properties(mpiCreateDate) := GetYoutubeDate(xYoutube.root.childvalues('published'));
    finally
      xYoutube.free
    end
  end
end.

Hi,
Glad to help you.
Yes, it's all about regional settings that I missed to comment on.
The code could be optimized in order not to depend on them.
Bear in mind that it makes an API request to Youtube for every single podcast item. So if the podcast consist of the maxim number of 50 items per page (it's a Youtube constraint) the update will take considerably longer than usual.

Regards

Yes, but in the end it takes at least 50 times longer than without this extra.

I wrote this code for myself and didn't think to make it universal. But these are the functions to circumvent regional settings. Well done.

As far as I know WMS does not export such a function. Recently I had a discussion with Eugene about Unix epoch timestamp to TDateTime conversion and he implemented a pair of functions: TimeStamp1970ToDateTime <-> DateTimeToTimeStamp1970. Maybe he could help again though this particular conversion is service dependent. For instance Vimeo does use a little bit different time format:

Youtube timestamp -> 2010-05-30T23:23:59.000Z
Vimeo timestamp -> 2011-02-21 19:00:02

I think it's not a good idea WMS to contain functions which are content bound. So we have to be creative.
