Implemented Non-Linear (Smart) Stretching of 4:3->16:9 - Page 5

Darre · 2007-12-17, 20:28

To have this in the viewmode switcher would be awesome. For now I only use this one.

LXTR · 2007-12-18, 08:47

I guess it doesn't work as well as it could with avi movies. In my case, it always strech all movies, it doesn't matter if they are 4:3, 16:9, 1.79:1, 1.85:1... it always fills the screen, so if you see films, you see people with some enlargement. Maybe it works well with TV, cause there's only two aspect ratios on it.

Darre · 2007-12-18, 09:13

This zoom mode doesn't recognize what input you got, its meant to be used on 4:3 content only. To get auto-switching you need the view-mode switcher plugin.

LXTR · 2007-12-18, 09:28

So then... what´s the difference between this aspecto ratio and the strecht one included in MP?

ol263 · 2007-12-18, 11:20

As mentioned by Darre, this zoom mode assumes the source aspect ratio is 4:3, it shouldn't be used for non 4:3 content.

The difference between stretch and this one, is this one stretches the side more than the middle, so the middle area loses proportion much less.

Thanks a lot both of you! Really usefull your help indeed. Just a question more... Is there any way of make a rule so when the pciture is 4:33, then this aspect ratio is aplied, but if it's is not, aply normal aspect ratio by example?

(i suppose i'm asking for too much, sorry...) ;-)

Hi ol263.

I really like your new zoom mode. Maybe I have an idea to make the things a bit easier for the people (and your self)
Easier as the implementation of a complete new zoom mode (which requires changes to many file or even plugins like the viewmodeswitcher) would be the replacement of an existing zoom mode.
I personally have changed your patch to replace the "Pan&Scan"-mode which is not interesting for a user with a 16:9 screen.

Bye
Lars

Darre · 2007-12-18, 16:31

So lkuech will you include this in a new svn? Or are you (or the author) going to post a patch that does just that? would be great because then its easy to implent in viewmode switcher without changing that plugin.

That's just what ViewModeSwitcher does, see previous 2 replies.

That would be indeed much easier, requiring changes to only 2 or 3 files.

To extend on that some more I might do:
- Change the Pan&Scan parameters depending on the screen dimensions: If it's 4:3, use classic pan&scan, if it's 16:9 use this mode.
- Change the AR name in the strings.xml file, instead of calling it "Pan&Scan" or "Smart 4:3->16:9", just call it "Smart", which would represent both cases.

ol263 · 2007-12-18, 23:27

OK, i've done the above, see the original post for details.

I assume it should work with ViewModeSwitcher, though I haven't tried.

Please note what I wrote there about overwriting the previous version with the new one. Don't! Restore the official binaries first and then install the new version.
