Because of the enabled auto brightness I want to show the current brightness as its is shown in the log: ---8<--- [1] [NTC] [VID] [May 05 21:58:51] v4l2_set_control: setting control "Brightness" to 4 (ret 0 ) [1] [NTC] [VID] [May 05 21:58:54] v4l2_set_control: setting control "Brightness" to 7 (ret 0 ) [1] [CRT] [VID] [May 05 21:59:01] mjpegtoyuv420p: Corrupt image ... continue [1] [NTC] [VID] [May 05 21:59:56] v4l2_set_control: setting control "Brightness" to 10 (ret 0 ) [1] [NTC] [VID] [May 05 22:00:10] v4l2_set_control: setting control "Brightness" to 13 (ret 0 ) [1] [NTC] [VID] [May 05 22:00:44] v4l2_set_control: setting control "Brightness" to 16 (ret 0 ) [1] [NTC] [VID] [May 05 22:00:46] v4l2_set_control: setting control "Brightness" to 19 (ret 0 ) [1] [NTC] [VID] [May 05 22:00:47] v4l2_set_control: setting control "Brightness" to 22 (ret 0 ) [1] [CRT] [VID] [May 05 22:01:40] mjpegtoyuv420p: Corrupt image ... continue [1] [NTC] [VID] [May 05 22:02:20] v4l2_set_control: setting control "Brightness" to 25 (ret 0 ) [1] [NTC] [VID] [May 05 22:02:22] v4l2_set_control: setting control "Brightness" to 28 (ret 0 ) [1] [NTC] [VID] [May 05 22:03:10] v4l2_set_control: setting control "Brightness" to 31 (ret 0 ) [1] [NTC] [VID] [May 05 22:04:17] v4l2_set_control: setting control "Brightness" to 34 (ret 0 ) [1] [NTC] [VID] [May 05 22:04:52] v4l2_set_control: setting control "Brightness" to 37 (ret 0 ) [1] [NTC] [VID] [May 05 22:04:54] v4l2_set_control: setting control "Brightness" to 40 (ret 0 ) [1] [NTC] [VID] [May 05 22:06:30] v4l2_set_control: setting control "Brightness" to 43 (ret 0 ) [1] [NTC] [VID] [May 05 22:06:31] v4l2_set_control: setting control "Brightness" to 46 (ret 0 ) [1] [NTC] [VID] [May 05 22:09:49] v4l2_set_control: setting control "Brightness" to 49 (ret 0 ) [1] [NTC] [VID] [May 05 22:11:51] v4l2_set_control: setting control "Brightness" to 52 (ret 0 ) [1] [NTC] [VID] [May 05 22:11:54] v4l2_set_control: setting control "Brightness" to 55 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:33] v4l2_set_control: setting control "Brightness" to 61 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:34] v4l2_set_control: setting control "Brightness" to 67 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:35] v4l2_set_control: setting control "Brightness" to 73 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:36] v4l2_set_control: setting control "Brightness" to 79 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:37] v4l2_set_control: setting control "Brightness" to 85 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:38] v4l2_set_control: setting control "Brightness" to 91 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:39] v4l2_set_control: setting control "Brightness" to 97 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:40] v4l2_set_control: setting control "Brightness" to 103 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:41] v4l2_set_control: setting control "Brightness" to 109 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:42] v4l2_set_control: setting control "Brightness" to 115 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:43] v4l2_set_control: setting control "Brightness" to 121 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:44] v4l2_set_control: setting control "Brightness" to 126 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:45] v4l2_set_control: setting control "Brightness" to 131 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:46] v4l2_set_control: setting control "Brightness" to 135 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:47] v4l2_set_control: setting control "Brightness" to 139 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:48] v4l2_set_control: setting control "Brightness" to 142 (ret 0 ) [1] [NTC] [VID] [May 05 22:33:49] v4l2_set_control: setting control "Brightness" to 145 (ret 0 ) --->8---

The use of the 'auto_brightness' is generally discouraged since it provides such poor results (as I can see from the log messages). It is better to set this manually in the configuration and review the results. As such, we will not be adding this to the images.

I record timelapse videos from dawn to dusk and what you see in the log is the auto brightness ajustment at dusk (you might check this according to the timestamp) so your interpretation is misleading.
