Description
Hallo,
I'm now the proud owner of a 16:10 display. Because I have several 4:3 video material I'd like to use the »-panscan« option also for cutting of top and button parts of 4:3 video to zoom in.
Is this possible with the logic behind this panscan option?
Thanks
Lars

At least I have been able to crop to and bottom, so closing.
If you cannot get it to work, provide details.

I think you might have misunderstood me.
When I watch a 16:9 video on a 4:3 display and I use the »-panscan« option then left and right parts of the video get cropped so there are no black parts left on the screen.
I asked for an enhancement so that 4:3 video gets autmatically cropped at top and bottom with the panscan option on a 16:9 display.
I know this could be done with other (cropping) options, but this is true for the behaviour of panscan too. I thought the panscan option was introduced to simplify this.

Ah. Well, I just use negative panscanrange values and adjust it during playback, seems much simpler to me.
But anyway, implemented in SVN r25810.

The problem with negative panscanrange is that you don't know the exact value to use. With panscanrange=1 you use panscan with values between 0 and 100% for scaling.
But I see this seems to be no a valuable feature to be added.
I had a short look at the aspect.c file and think the aspect function could choose the »pandirection« depending on the relation of display_asr to video_asr. But I'm not a programmer.
(scrw/scrh)*monitor_pixel_aspect : (prew/preh)
Thanks anyway.

Huh? I said I implemented it in r25810, say if that's not what you expected.
That is completely normal behaviour for panscan, but by default you usually have to crop before you can use panscan.
See -panscanrange if you want to do without cropping.
