Comment (by villmer):

 The output from the terminal shows:
 Input '''#0 has start: 377.919269''' while  Input '''#1 has start:
 378.792375'''

 - - - -

 As there is approximately a ~1 second time lag between the 1st and 2nd
 inputs, we tried adding a filter to change the 2nd input’s time stamp:
 -filter_complex
 "'''[1:v]setpts=(PTS-2)/TB[mod]''';[0:v][mod]framepack=sbs" \
 This did not work.

 We also tried adding the -vsync option to both streams:
 -f v4l2 -input_format h264 -video_size 1024x1024 -framerate 20
 -thread_queue_size 32k '''-vsync 0''' -i /dev/video0 \
 -f v4l2 -input_format h264 -video_size 1024x1024 -framerate 20
 -thread_queue_size 32k '''-vsync 0''' -i /dev/video1 \
 This did not work.
