Description King_DuckZ 2011-02-23 13:44:02 UTC
Version:           unspecified (using KDE 4.5.5) 
OS:                Linux

Thumbnail creation of multimedia files (especially videos) causes the DVD head to seek to and fro. I'm assuming those thumbnails are built by multiple threads/processes, but while this may be optimal on regular disks, it causes slowdowns on optical readers.

Reproducible: Didn't try

Steps to Reproduce:
Create a DVD with multiple videos that are big enough (eg mp4, ogm and so on, 300+mb each)
explore the dvd with dolphin or equivalent
listen to the dvd reader's noise as it tries to keep up with the read requests (most evident on notebooks)


Expected Results:  
If the architecture allows this, the code spawning multiple processes should only load one preview at a time if source data comes from an optical disk reader.

What video thumbnailer are you using?
MPlayerThumbs or FFMpegThumbs?

Is this still an issue with KDE Frameworks 5.47?
