[mythtv-users] 16x9 stretch mode on ConvertX sourced streams

[Dave Pippenger]

I enabled debugging on my frontend and as far as I can tell it's doing 
something when I change to 16:9 Stretch from 16:9, but it's just not doing 
the right thing...

==========================================================================
These are the values from my plextor generated mpeg4 stream

16:9 Stretch...

2006-02-16 22:35:20.806 Image size. dispxoff 112, dispyoff: 0, dispwoff: 
855, disphoff: 480
2006-02-16 22:35:20.806 Image size. imgx 0, imgy: 0, imgw: 720, imgh: 480


16:9...

2006-02-16 22:35:24.636 Image size. dispxoff 113, dispyoff: 0, dispwoff: 
854, disphoff: 480
2006-02-16 22:35:24.636 Image size. imgx 0, imgy: 0, imgw: 720, imgh: 480

==========================================================================

And these are the values from my pvr-250 mpeg2 stream

16:9 Stretch...

2006-02-16 22:41:06.352 Image size. dispxoff -30, dispyoff: 0, dispwoff: 
1140, disphoff: 480
2006-02-16 22:41:06.352 Image size. imgx 0, imgy: 0, imgw: 720, imgh: 480

16:9...

2006-02-16 22:41:24.456 Image size. dispxoff 112, dispyoff: 0, dispwoff: 
855, disphoff: 480
2006-02-16 22:41:24.456 Image size. imgx 0, imgy: 0, imgw: 720, imgh: 480
=========================================================================

So it seems it's not coming up with the right scaling of the image on an 
the mpeg4 stream for some reason. I'm going to try and dig into the source 
a bit and figure out what changed between 0.18 and 0.19 with the way it 
determines the output scale after applying aspect override.
