FS#604 - ID3 info not being displayed (Rioport id3v2 bug)

Daily builds after 12/01/2002 do not display all of the ID3
information on some (not all) of my MP3‘s (Builds
11/30/2002 and earlier properly display this info)

This seems to affect MP3‘s that I ripped using Rioport
audio manager - MP3‘s ripped with MusicMatch display
OK.

Jukebox Recorder 20
Firmware 1.28
HW Info:
ROM: 1.28
Mask: 0×0302 USB: positive
ATA: 0×200 PR: positive
Freq: 11.0592MHz

Can you upload an exampe to use for debugging?

Here is an MP3 that displays properly in the earlier builds,
but not in the later ones.

Thanks for all your efforts.

Sorry…

I’m trying to upload an MP3 for an example, but I can’t
figure out how to attach a file to a follow up comment. I
started a new thread to attach the file, but it was too big
and did not attach ( the file is ~1.2M).

Is there an easy way to ‘truncate’ an MP3 so I can upload
it?

Finally… chopped up an MP3 using WordPad, and posted
it under thread #651224 (I still can’t see how to attach a
file to a followup comment)

Thanks

I have examined your file and I saw what was wrong. Rioport
has the silly habit of adding empty ID3 frames (length = 0)
in the tag. I quote from the ID3V2.3 specification:

“A frame must be at least 1 byte big, excluding the header.”

So Rioport violates the ID3V2 standard. Send them an email
and complain about them generating invalid ID3V2.3 tags.

FYI, we added the length=0 check the 28th of October.

The reason it worked for you may be that the “working” files
contain both V1 and V2 tags. December 3 we changed the ID3
code so it ignores the V1 tag if there is a V2 tag. So now
it tries to use the V2 tag, encounters the invalid frame and
aborts.

I’ve just found the same problem, having downloaded the
lastest daily build.
any suggestions for how I can see if it’s caused by the same
empty frame issue? (a binary sequence to look for in the
file, perhaps?)

I only have it on some MP3s, and I’m guessing that they’re
the ones I did when I was using Real Jukebox, which I
stopped using some time ago now.

If it is the same cause, I’ll just try to fix the broken MP3s.

Thanks,
Rob
