knight_of_ni Posted February 24, 2009 Share Posted February 24, 2009 When I try to add an ogg file an error window is displayed with the message "external exception EEFFACE". Flac and mp3 files are added with no problem. It also displayed a filter problem before the above message, but I installed Xiph.Org Ogg codecs and it disappeared. Thanks for any help you can give.

LIGHTNING UK! Posted February 24, 2009 Share Posted February 24, 2009 Are you saying that all your ogg files do this or just the one? Link to comment Share on other sites More sharing options...
knight_of_ni Posted February 24, 2009 Author Share Posted February 24, 2009 No it doesn't do it with all files and I just found that in the files that the problem occurred, in metadata there was a field called <COVERART_UUENCODED> and had ASCII characters in it. I ripped the cds with Easy cd-da extractor. Once I removed that field with mp3tag, the problem was gone. Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted February 24, 2009 Share Posted February 24, 2009 If you still have an example of such a problem file, I'd like to have a play around with it myself to check the crash was in the directshow filter and not ImgBurn itself. Is there any chance you could email it to the support address in the program's 'About' box? Link to comment Share on other sites More sharing options...

LIGHTNING UK! Posted February 24, 2009 Share Posted February 24, 2009 Thanks. Now I'm no expert on the ogg/vorbis comments but it would appear to me that the field length of the COVERART_UUENCODED is wrong in the file. It lists it as 32250 bytes when in actual fact it should be 32558. Comments are laid out like this... As such, ImgBurn tries to read the next comment's length from a place that's in the middle of the previous comment and is then getting some huge value for the length - which the program cannot then allocate memory for and it causes a crash. I've implemented a sanity check whereby if the comment size exceeds the file size it'll just bomb out of parsing the comments. Link to comment Share on other sites More sharing options...

An excellent program by the way, I 've kissed other burning programs goodbye. Keep up the good work! Link to comment Share on other sites More sharing options...
