#2581: Allow changing of aspect ratio when transcoding

     Type:  enhancement      |      Status:  new 
 Priority:  minor            |   Milestone:  0.21
Component:  mythtv           |     Version:  0.20
 Severity:  medium           |  
 This is a patch against 0.20 that accomplishes a couple of things.  First,
 I've included my original fixes from #2198 on this, so 1080i streams are
 resized properly.  Secondly, I've added a new setting for MPEG4
 transcoders that sets the aspect ratio.  This is exposed as a new option
 called "Aspect Ratio" with a drop-down menu that provides the options of
 "Leave", "4:3", and "16:9".

 When selecting a different aspect ratio, the transcoded file will be
 cropped to the proper aspect ratio.  So if the source is a 16:9 file
 recorded from an HDTV channel and the mpeg4aspectratio is set to 4:3, the
 sides will be cropped off when transcoding.  This is very helpful for when
 you've recorded an SDTV program on an HDTV tuner (like the Simpsons).

 Likewise, when set to 16:9, this will crop the tops off the file, which is
 useful if you've recorded a letterboxed program on an SDTV feed.

 This helps to make the files more portable, makes watching recorded
 programs in MythTV behave properly when using a zoom mode, and may even
 promote world peace.  If the powers that be conclude that this makes
 sense, I'll work on porting it to SVN.  Unfortunately, right now I'm not
 running SVN because my wife likes a working myth box.
