flac import: sometimes date is lost (Bug?)
« on: March 24, 2012, 06:45:22 pm »

Hi,

thank you for this fine piece of code! This is the only solution i know, that is working, mostly correctly, easy and in expected manner.

i'm ripping my music with the flac-encoder in dbPoweramp. After importing music files into JRiver (newest version) sometimes date is lost in the tags (data-formats area "2005 05 22" or only "2005"). Even if these flac-files are converted to AAC with date displayed corrctly in the OS-explorer, the information is lost in JR.

Any idea?

Thanks,
Martin

Let's see what the actual tags are.

1. Select a track.
2. Open the Tag Action Window (lower left in Standard view).
3. Click the area shown in the attached image.
4. Copy/Paste the tags in a reply here.

Here are the results of one track tested a few days ago:

***********************************************
Free Lossless Audio Codec (FLAC)
  44,1 kHz Sample Rate
  16 Bits Per Sample
  2 Channels

  Min Block Size = 4608
  Max Block Size = 4608
  Min Frame Size = 16
  Max Frame Size = 15165
  Padding Block = 472344 bytes

# of Pictures = 1
  Type 3 (50953 bytes)

Vorbis Comment Block (985 bytes):
  Vendor String =

  Organization = Naidoo Records
  UPC = 693723660929

  ALBUMARTIST = Xavier Naidoo
  TRACKNUMBER = 1
  TOTALTRACKS = 14
  DISCNUMBER = 1
  TOTALDISCS = 1
***************************************************

I quickly checked other tracks and most of them don't have any "Date=" tag like this here. Besides all tracks checked have allways a condition displayed like "<Too Long To Display> on different tags.

Ok, I see.

According to the Voribis Comment spec, the tag is not a valid DATE tag.

Quote
Date and time

The goal is to specify one standard format for describing date and/or time.
ISO proposal

The date format for any field describing a date must follow the ISO scheme: YYYY-MM-DD, shortened to just YYYY-MM or simply YYYY.

We have been recommending this usage with the DATE tag for some time. It is proposed that the spec be amended to include this information for machinability.

The time format for any field except track duration must be specified with leading T and ending with a time zone. Schemas with and without dates:

   YYYY-MM-DDTHH:MM:SS+TS

   THH:MM+TZ


I've been able to create a file like this, but can't get MC to recognize or read this tag.  Probably either the FLAC input plug-in doesn't accept the tag as valid, or MC discards it because it isn't a valid DATE value.  In either case, I can't get MC to provide the value.

Perhaps you can have one of the other utilities modify the DATE tag to produce the date in the acceptable formats (mentioned above).
