Re: [Gtkpod-questions] Gtkpod uses a lot of CPU during format conversion

[Jorg S. <jor...@gm...>]

gtkpod does three things:

1) monitor output of the scripts and paste it into the details window, I think 100x per second

2) update the display every time a track has been completed

3) 100x per second: check if new conversion threads should be started, conversions have finished etc. Starting a new thread is rare as each started thread checks for itself for the next available track in the scheduled list.

Only 1) could take a significant amount of time I think. Did you try closing the details window? GTK+ can be slow.

If you want to look at the code it's all in file_conversion.c and .h

JCS.
