hse Posted April 7, 2019 Share Posted April 7, 2019 (edited) 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? https://i.imgur.com/oeGLb7H.jpg support.zip EDIT: here is a comparison with another channel working http://screenshotcomparison.com/comparison/133467 Edited April 7, 2019 by Griga topic title corrected Quote Link to comment
Griga Posted April 7, 2019 Share Posted April 7, 2019 Looks like the channel specifies a non-standard aspect ratio in the video headers. Please post a screenshot that shows what the DVBViewer Filter property page displays when this channel is played. Quote Link to comment

Griga Posted April 7, 2019 Share Posted April 7, 2019 (edited) 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. Edited April 7, 2019 by Griga Quote Link to comment
hse Posted April 11, 2019 Author Share Posted April 11, 2019 Hey again Griga. Setting aspect ratio to 4:3 then applying a custom zoom does indeed fix the issue. https://i.imgur.com/m2kW7mf.jpg 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. -hse Quote Link to comment
