Description

Latest SVN (7308) has problems generating thumbnails from recordings on the backend. It seems to hang but is just very slow. The backend logs shows the message:
2005-09-24 13:56:01.602 Invalid file handle when opening /media/video/1135_20050923190000.mpg.png. 4 retries remaining.

The backend creates PNG files for each recording that are only 136 bytes long, as opposed to the proper thumbnails which are around 30K. I have done a distclean and recompile on both front and back. Recordings made before the update show and generate thumbnails correctly. New recordings don't.

I'm seeing this as well. In fact, I was just about to report it.

Thumbnailing works now with recordings made after version 7308 (for me anyway). Thanks.

Resolution: fixed
Status: newclosed

This only effects recording made with [7284] through [7308].

These recordings can be fixed with the mythcommflag in [7308] or later.

As of Changeset [7364], the NVP preview generation method outputs the detailed instructions for doing this to your backend log when you hit one of these files.
