Hello,
Using the kmssink with can-scale=true produces a terrible stretched result on an hdmi 1920x1080 display. If I set can-scale=false then there is no video display and no error produced.

Using ti-processor-sdk-linux-rt-am57xx-evm-06.03.00.106.
It seems like there are two issues here:
1. the decoder is outputing 768x464
2. the vpe doesn't know how to frame it within 1920x1080.
How can I make this work?
Thanks,
Stef
