A file which gtkpod cannot open none

Description Phip 2009-07-02 21:06:24 UTC
Created attachment 350349 [details]
A file which gtkpod cannot open

Description of problem:
Gtkpod gives an error when trying to add .m4a files that it previously accepted.

Version-Release number of selected component (if applicable):
0.99.14-2.fc11

How reproducible:
Always

Steps to Reproduce:
1. In gtkpod with an ipod loaded, click 'add files' or 'add folder'
2. Make selection to include .m4a files
  
Actual results:
Error dialog opens, with two messages:
- Could not open '/path/to/file.m4a' for reading, or file is not an mp4 file.
- The following track could not be processed (filetype is known but analysis failed): '/path/to/file.m4a'

Expected results:
Successfully adding the file to my ipod as it did in the (uncertain but not-too-distant) past.

Additional info:
The files in question were encoded by iTunes 7 for Mac OS and have worked previously with gtkpod and continue to be playable. A sample can be uploaded if needed

I helped someone in #gtkpod debug this the other day.  It seems that the libmp4v2 in F-11 cannot parse most .mp4/.m4a files.  I used mp4info on a file that gtkpod failed to read and it failed to read it as well.  The same files parse fine with gtkpod and mp4info on F-10.

Any ideas what changed in libmp4v2? It seems like a pretty big problem for libmp4v2 to not be able to read mp4 files...

Comment 3 Todd Zullinger 2009-08-02 19:35:41 UTC
I think the problem was due to a bad libmp4v2 build.  It might have been built at a time when gcc or some other component of the tree was a bit flaky.  There is an updated libmp4v2 available (libmp4v2-1.5.0.1-9.fc11) which fixes this issue.  This was apparently reported in bug #507302.

I've verified that the update fixes mp4info.  I did not test it with gtkpod, but I fully expect it to work.  If it does not, please reopen this bug.
