New Revision: 20150
   Changeset: http://cvs.mythtv.org/trac/changeset/20150

Modified:

   trunk/mythtv/filters/yadif/filter_yadif.c
   trunk/mythtv/programs/mythfrontend/globalsettings.cpp

Log:

Refs #20129. Enable multiple threads in the yadif deinterlacer.

The number of threads follows the max cpu setting in the playback profile and the default, single thread behaviour is unchanged (i.e. it uses the existing thread rather than creating a new one). As a benchmark, using 2 threads gives smooth playback of 1080i MPEG2 material on my Core2Duo at 2.0Ghz (total mythtv utilisation ~130%) whereas it was previously unplayable.

Also some general code tidying.
