[gst-devel] CPU consumption when decoding mp3

[Vincent Meserette]

Hi all,

I am writing an audio player application which runs on a AMD Geode @500MHz
processor.
If I use the libgstflump3dec plugin for mp3 decoding, it takes 25% of the
CPU for reading one file, against 15% with the libgstffmpeg default plugin.
Do you know if it is normal to have such a difference ?

Moreover, I made a little test by launching several mp3 at same time with
the following commands :

gst-launch-0.10 playbin "uri=file:///home/mymp3_1.mp3" &
gst-launch-0.10 playbin "uri=file:///home/mymp3_2.mp3" &
gst-launch-0.10 playbin "uri=file:///home/mymp3_3.mp3" &
gst-launch-0.10 playbin "uri=file:///home/mymp3_4.mp3" &
gst-launch-0.10 playbin "uri=file:///home/mymp3_5.mp3" &

I reach almost 100% of CPU consumption, the playing stops, but the threads
are not killed.
Do you know if there is a way to specify to gstreamer in my application to
not launch the playing when i reach too much CPU consumption ?

Thanks in advance for your reply

Kind regards
