We don't maintain MLT ourself. It is the job of the MLT team.
We are aware about a lot of issue with MLT and it is one of reasons why we
have developped our own librairy (Libopenshot). which will be
Multi-processor.

Take a look at this page who will explain you better than me what can
provide you this new librairy :
http://www.kickstarter.com/projects/421164014/openshot-video-editor-for-windows-mac-and-linuxand
on our official blog
(http://www.openshotvideo.com/).  And why not to help us to reach this
purpose.

> Title:
>   CPU 100%

> Status in OpenShot Video Editor:
>   Invalid

> Bug description:
>   This bug derives from Question 78804 CPU 100% from upromis
>
>   it is possibly connected with Bug 403154
>
>   Bug is that processor runs at 100% all the time, or if multi-processor
>   then one is at almost 100% and another is also being used by Openshot
>   at same time so a 3 processor system can have 60% of total processor
>   time used by OpenShot.
>
>   What I have now found is this:
>
>   The 100% processor time can be switched off by opening the "Export"
>   dialogue, and then either exporting a file, or even just by cancelling
>   the export before doing anything. This sends a signal to stop whatever
>   process is looping.
>
>   Whatever function is being called to stop the looping when the export
>   dialogue is closed, needs to be added to the initialisation when
>   opening OpenShot, and when opening a project, and whenever any
>   activity happens regarding playing of clips.
>
>   If I simulate this by opening and closing the export dialogue at all
>   these times, OpenShot works much more smoothly, and so far without
>   problems.
>
>   I am not yet familiar enough with the code base to find it in the code
>   yet.
