before .ogm 16:9; after, 4:3.

[primitive]

Hello people, I made an .ogm file from a 16:9 xvid avi + two vorbis audio streams + one srt subtitle stream. When I do this, on playback black bars are added to the top and bottom of the video to make it 4:3. I have also noticed that some of my other files who have a ~4:3 aspect ratio (close enough to be unnoticable but not exact) are padded to make them 4:3.

I was wondering if there was a way to disable this behavior. The two most-used players that I know of (WMP and Sasami) will play the movie correctly full-screen without this kind of padding. (The only other player I use that doesn't display this behavior is ATI's File Player, which blows goats all around.)

I'm resizing the picture in the subtitle muxer to have space at the bottom to draw the subtitles. Otherwise the subtitles would be always in picture. I think that wouldn't be very nice ;)

As you might have noticed this only happens if your video contains subtitles.

Best regards,
Tobias

I didn't notice it before, but yea, I see it now.

So will it always pad a subtitled movie to 4:3, even if it's already 4:3? What's the processor overhead?

And what's this going to do to TV-out to a 16:9 TV? ;)

The CPU overhead is nearly nothing because I pass already a bigger buffer to the video decoder (which was quite difficult to achieve). My experience is ca. 1%.

Currently you can not set the aspect ratio in the property page but anyway you can set it in the registry:

- Goto [HKEY_CLASSES_ROOT\CLSID\{00A95963-3BE5-48C0-AD9F-3356D67EA09D}\Defaults]
- Create a DWORD entry with the name "AspectX" and set it to 16
- Create a DWORD entry with the name "AspectY" and set it to 9

You can change the aspect ratio now in the property page. (version 1.1.2.2)
