FS#7981 - Missing tag data (and crashing) if WMA track has comment

The WPS does not display album name, genre, or track number, on certain WMA tracks (it does always display artist name and song title). This problem seems to correspond to whether I have a comment in the WMA track tags. If I don’t have a comment, everything displays fine, if I do, then the data I mentioned is missing. Mp3 and FLAC do not seem to have this problem.

Also on these tracks (WMA with comments), the player freezes when I go to ‘Show Track Info’ from the WPS Context Menu.

(Also I’ve not been able to build my database since I put a bunch of WMA tracks on my player, I don’t know yet if this is for the same reason)

I tested this with release 15162.

Reason for closing:  Fixed
Additional comments about closing:  

Database building doesn't choke on long tags, nor does Show Track Info cause problems. Tested with the file from  FS#8500  .

Would you be able to provide a sample file demonstrating this bug?

Shiloh Hawley commented on 2007-10-17 17:43

Sure I will attach it here. The comment tag is from the Tag&Rename program. I found that if I got rid of the comment, the problem went away.

I was mistaken above when I said mp3 and flac files do not have the same problem. I have seen the same problem with a some mp3 files as well. If anyone would like more information, testing, samples, etc, please let me know.

I’ve finally got around to testing your file.

There appears to be two problems:

1) Rockbox only has a relatively small buffer available for storing the metadata about a track. This buffer is filled in the order the tags are in the file, and because the comments tag comes before the other data, this means the buffer is full before it can read those remaining fields, so it skips them. This may be changed now that the “metadata-on-buffer” feature has been implemented.

2) There does seem to be a bug in the “view track info” screen which causes Rockbox to freeze when displaying a very long comment. I haven’t investigated this any more.

Ok thank you for looking into it. I’ll test it again with the latest firmware. I’m not particularly attached to the comments, so stripping them off isn’t a problem for now.
