About your suggestion; I'm wondering when and how the video stream aspect ratio would be incorrectly detected. Isn't it enough to set it once and for all for each channel?
>From a user point of view, it seems to me that it wold be nice to get away from the concepts of aspect ratios, zoom and stretch. All the user cares about is where the black bars are and how thick they are. So I'd like to see the following three options:
1. Zoom to remove vertical black bars. (your b)
2. Zoom to remove top and bottom black bars. (your a)
3. Zoom to midpoint between 1 and 2.
These three modes would not just consider the aspect ratio and size of the video stream, they would also look at the actual image content, which would be useful for dvb channels that sometimes broadcast a 720 wide image with thick black bars on the left and right side. Without looking at the pixels, there is no way to determine whether those bars are there or not.

Hi,
As I'm sure others will also tell you, there already is a simple
mechanism for this. If you hit 'w' then the system will cycle
between various 'aspect ratio overrides'. Two of them are 'Fill',
which zooms in so that the image fills the entire screen, and 'Off',
which zooms out so that the entire image fits on the screen. It also
has a bunch of other settings there which allow you to override the
aspect ratio in other ways. There is also a global setting that
allows you to set the default. My global setting is "Fill".
Anyway, if you're still interested in coding, there is still stuff
there that could be improved (he says without an attached patch :).
In particular, the current options conflate a few things that might
be separated: What happens when the aspect ratio of the video stream
is incorrectly identified, and what do you do when the video aspect
ratio doesn't equal the screen aspect ratio. These should be two
separate controls, but are currently both in the list of options you
switch between with 'w', making that list longer than it needs to be.
If the two aspect ratios are not equal then there are a bunch of
ways to resolve that, but the three main ones are a) Zoom in to fill
the entire screen (currently 'Fill'), b) Zoom out to see the entire
image (currently 'off'), and c) stretch the image to match aspect
ratios. I'd have 'w' switch between just these three options. Then
there should be a second button to allow the system to override the
video stream aspect ratio: "No override", "4:3", "16:9". The display
aspect ratio doesn't need to be set dynamically.
Be well,
Will :-}
