I am using the custom Raspivid file from the SLP image on my own version of Raspian Buster. I have written a python script utilizing openCV to create a blank, fullscreen window that displays sensor data from a BME280 at the top of the screen in real-time. Then, I go into terminal to startup Raspivid and the python script at the same time. When I use Raspivid with the side-by-side mode, everything runs flawlessly and as expected. However, when I run Raspivid with the top-bottom mode (which I need for the screen I am using), the video feed freezes. When just running Raspivid in top-bottom mode, or the python script by itself, there are no issues, but running them at the same time causes Raspivid to freeze.
If I enter this command with side-by-side mode, it runs great and works as expected.
Code: Select all
raspivid -3d sbs -w 1080 -h 1920 -p 68,64,1016,1792 & python ./bme_display.py

If I enter this command for top-bottom mode, the video feed freezes.
Code: Select all
raspivid -3d tb -w 1080 -h 1920 -p 68,64,1016,1792 & python ./bme_display.py

If I enter this command to just run the Raspivid in top-bottom mode, the video feed runs just fine.
Code: Select all
raspivid -3d tb -w 1080 -h 1920 -p 68,64,1016,1792

I'm not sure what is causing this issue and any help would be greatly appreciated!
