Mythtv frontend crashes playing ISO in storage group

[scolbeck]

Binary package hint: mythtv-frontend

Mythtv 0.24 added support for playing unencrypted DVD ISO images from a video storage group. However when I try to play any unencrypted DVD ISO image from the video storage group, it crashes the Mythtv frontend. I have no problems playing the same ISO images outside of the storage group from a NFS mount. This is 100% recreatable on both my frontend machines. The ISO images were created using DVD Shrink.

I am using Mythbuntu 10.10 with the 0.24 Mythbuntu repos.

I have an apport report for the crash but cannot upload it due to I think bug 95822 (https://bugs.launchpad.net/ubuntu/+source/apport/+bug/95822).

In the attached mythfrontend.log file, I attempted to play the ISO at 2011-02-08 18:01:50.765.

I found out this problem exists with ISOs created with DVD Shrink. I pulled out my DVD discs and created ISO images with another program and they play fine in a storage group. Interesting MythTV has no problem playing the same DVD Shrink ISOs outside of a storage group.

This might be related to http://code.mythtv.org/trac/ticket/9844

Can someone verify if having the extension ISO be lower case makes any difference?

[scolbeck (scolbeck)]

Yes, the problem does look to be caused by the .ISO extension in upper case. When I renamed the ".ISO" to ".iso" the movie plays fine. Thanks!

Marking this as fix committed. This was committed upstream to 0.24-fixes so we should see this in tonights builds. (may have been in last nights builds)

0.24 in oneiric.
0.25 in precise. -> fix released.
