Thanks for the response. You're right, it isn't what I wanted to hear... but better to know the truth...
(Unfortunately, I can't use another app, since only SlingSudio's app will use Sling Studio's video encoder, and it won't recognize anything else.)
But, maybe you can help me understand what's happening under the covers of Graphene? On windows or Linux, when I develop, I have had to move from 32Bit to 64Bit applications before. It was always simply a matter of having the right underlying libraries.
I read online (on the XDA Forum) that the 32Bit libraries are still available for the Pixel 7, Google just has a check that it put in place, and then simply denies 32 Bit apps, forcing everyone to move to 64 Bit. Is that check in the firmware of the phone? Or, why can't Graphene remove it? ("We don't want to support 32BIT either" is a legitimate response... I just am curious.)
