Comment (by thender):
To explain a little more precisely:
Originally, the first recording worked, but the second one would not. The
error one would receive on the second record was this.
''[video4linux2,v4l2 @ 0x1584f80] The v4l2 frame is 0 bytes, but 4147200
bytes are expected
Input #0, video4linux2,v4l2, from '/dev/video1':
''
Issues of this nature also had a tendency to happen in the middle of a
recording.
Now, the 2nd recording does start recording, but you get stuck with one
frame, that is the last frame from the prior recording. So you get a video
file of one frame, no movement with what is going on, and that video frame
in the 2nd recording that makes up the entirety of the recording is the
last frame from the first recording.
Here is the command line with debug.
ffmpeg -f v4l2 -framerate 30 -s 1920x1080 -i /dev/video2 -c:v libx264
-preset ultrafast -crf 10 microcorder.mkv -loglevel debug
