On my S21, the hardware decoder has a couple of problems.
- It won't decode from my HDHR Flex 4k. This includes both ATSC 1.0 and ATSC 3.0 streams. I can hear the audio but the display is black.
- Landscape mode has a problem with scaling. It appears that the height is the same number of pixels as in Portrait. However, the width is fully across the screen. It is crazy squished. Think of it as 16x9 stretch/squished into 20x5.
Hybrid and Software settings both seem to work OK. I don't know what the default was, but if it was Hardware, maybe it shouldn't be. I have been avoiding watching on my phone for months as the scaling has never worked. I just got the HDHR and obviously the no video is an even bigger problem. That sent me looking for a config solution and that is when I found the Video Decoder setting.
I am good for now with the other settings, but just wanted to make sure you were aware that it might be broken.
