[C#] Set framerate using directshow

PostTue Mar 05, 2019 9:37 am

Hi all!

I am currently trying to develop an application using directshow and c# to simple render a file to a decklinck vidéo render filter. The files are 720p 25hz and the output should be 1080i 50hz.
I managed to do the upscale from 720p to 1080 by setting the Deckclink vidéo converter to « HD 720 to HD 1080 ». I also defined all the ouptut pins to default vidéo standard « 1080i50 ».
The issue now is that for some reason, when I launch my program, the card automatically configure itself to 1080i60hz even if the source is a 720p25hz file.
Should i add a filter I don’t know? Or am I doing something wrong ?

I hope i am clear enough!

Thanks in advance!
Kr
