#2581: Allow changing of aspect ratio when transcoding
-----------------------------+----------------------------------------------

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.
