@6by9, looks like stereoscopic support has been broken in the latest kernels update.
If it take Buster image (Raspbian Buster with desktop, 2019-07-10, kernel 4.19.57
), both raspistill and raspivid works
with -3d option. I mean that after running these commands I have one stereoscopic image and one stereoscopic video with appropriate names:
Code: Select all
raspistill -3d sbs -o 1.jpg
raspivid -3d sbs -w 1280 -h 720 -o 1.h264
Before all these tests I just put our dt-blob.bin to /BOOT and enable camera in raspi-config.
If I do system upgrade with piwiz (and kernel is updated to 4.19.66
), both raspistill and raspivid stops working
. Both raspistill and raspivid has the same behavior in this case:
- preview is started
- preview image freezes
- adding '-n' option (no preview) has no any effect
- no image or video saved
- system can not be shut down correctly (sudo poweroff), and frozen preview image is always on the screen
I've also tested stock Buster with rpi-update (and updated kernel is 4.19.71
), but no luck too.
Could you please check this issue?
4.19.73-v7+ has been tested. Problem still exist.
