DVBViewer is stretching 16:9 channels.

Hello, I have a channel that is 16:9, DVBViewer detects it as 16:9, but it stretches the image

if I record the channel and open it with a media player it is displayed correctly and not stretched.

It worked fine last week. Any ideas how to fix?

The aspect ratio read from the headers is 544:297 = 1.83, which is outside the DVBViewer "catch range" for 16:9 = 1.78. That's why no 16:9 icon is displayed in the status bar.

 

However, DVBViewer scales the picture correctly according to the information in the video headers, which means, what you see is actually 544:297. For me it looks like a 4:3 picture wrongly squeezed to "near 16:9". IMO the broadcaster sends wrong headers. You can force a 4:3 aspect ratio in the Settings -> Aspect Ratio sub-menu. But that is no convenient solution, because you have to return to Aspect Ratio = Auto for other channels ;)

 

P.S. You can try to tick "Keep track of H.264 Aspect Ratio" on the property page. It will let DVBViewer recognize aspect ratio changes.

Hey again Griga.

Setting aspect ratio to 4:3 then applying a custom zoom does indeed fix the issue.

But like you said it has to by enabled and disabled each time I view one of these channels as it's a global setting that effects everything else :(

Could a feature be added in future updates to make aspect ratio and zoom settings, setable on a per channel basis instead of only on a global basis?

 

Thanks again for your help.
