unable to stream in 2k mode

nickel110 commented 2 years ago

Check the firmware version. 2K streaming requires version 1.10.1 or higher. https://support.theta360.com/en/download/firmware/x/

thanks for the advice

after updating the firmware to 1.20.0 I have been able to livestream at 2K using gst_viewer (by manually changing L249 of gst_viewer.c) however gst-launch-1.0 thetauvcsrc stopped working for both resolutions Screenshot from 2022-08-31 15-37-11

I have also been unable to capture images using gphoto2 since the firmware update getting and setting configs still work Screenshot from 2022-08-31 15-31-59

correction: for setting L249 of gst_viewer.c at either THETAUVC_MODE_UHD_2997 or THETAUVC_MODE_FHD_2997 in both cases the device continues to stream at 4K

update: to get 2K streaming working, we have to set L67 in thetauvc.c fps value to 30

** live streaming setting needs to be set to high quality(30fps) as well. 2K streaming doesn't seem to work at 15 fps
