MediaInfo.CreationTime property does not contain date

[Dylrak]

Issue

When a media file specifies both a date and a creation_time, the MediaInfo.CreationTime property ignores the date tag, instead being set to DateTime.Now plus the creation time.

Let's say that ffprobe E:\input.wav yields the following result:

date : 2016-03-31
creation_time : 10:15:35

Using Xabe.FFMPEG as follows:

IMediaInfo mediaInfo = await FFmpeg.GetMediaInfo("E:\input.wav");

will set mediaInfo.CreationTime to {01/15/2024 10:15:35}.

Suggested Fix

In FFprobeWrapper.SetProperties(), change creation_time to a TimeSpan and attempt to parse the date as well, adding them to each other. If only creation_time is specified, the old behaviour is kept:

if (!string.IsNullOrWhiteSpace(infos.format.tags?.creation_time) && TimeSpan.TryParse(infos.format.tags.creation_time, out var creationTime))
{
    mediaInfo.CreationTime = !string.IsNullOrWhiteSpace(infos.format.tags?.date) && DateTime.TryParse(infos.format.tags.date, out var date)
        ? date.Add(creationTime)
        : DateTime.Now.Add(creationTime);
}
