Title:
Powerpoint is slow to load
Status in OpenLP:
Confirmed
Bug description:
Originally reported in forum:
https://forums.openlp.org/discussion/3412/power-point-takes-too-long-
to-load
The problem is that when we load a PPT we generate thumbnails for the preview
and the slidecontroller, and extract notes and titles for showing on the stage
view. This data is stored in a folder which name is a md5-hash of the full path
of the ppt-file.
When a presentation is placed in the servicemanager, the file is copied to
the servicemanager folder, and when going live OpenLP creates a hash of the new
full path of the file (now in the servicemanager folder) which of course is
different from the old hash, and therefore OpenLP generates the thumbnails etc
again.
A few solutions could be made:
* Make the hash based on the file content instead of the file path (might be
a bit slow on big files).
* When adding a ppt-file to the servicemanager, copy the old folder to the
new hash-folder.
* Add the thumbnails etc to the service file.
