Hi folks,

I posted this message already on stackoverflow, but unfortunately noone answered, so I am trying it here, because there seems to be a fair amount of Gstreamer aficionados around here.
I apologise if you read this before. Thank you for any input.

------------------------------------------------------------------------

I've come across a really strange error which I am trying to narrow down to a certain point. Basically, I am writing a music player. On starting it, it just lists all songs in the chosen folder (and its subfolders) and the song length in a separate column. During the initialisation process Python and its libraries, wxPython and Gstreamer are used.

Everything works fine when using a small amount of songs (I've tried up to 20), but when using my entire music folder, I receive the following errors.

Code:
No accelerated IMDCT transform found

I would assume, it's got something to do with gstreamer and its ffmpeg codec, but what exactly is a mystery to me. Any help is very welcome.

Thanks a lot in advance.

P.S. My script is very large, so I left it out, because I am sure noone wants to trawl through 1000s of lines of code.
