I use the following command.
I am not sure if the output file is interlaced because mediainfo says
nothing about that for FFV1 encoder.

./ffmpeg -debug 1 -f pulse -ar 44100 -ac 2 -channel_layout stereo
-thread_queue_size 512 -i alsa_input.pci-0000_00_14.2.analog-stereo -f
v4l2 -ts mono2abs -channel 1 -video_size 720x576 -pix_fmt yuyv422
-thread_queue_size 512 -i /dev/video0 -c:v ffv1 -level 3 -flags
+ilme+ildct -aspect 4:3 -pix_fmt yuv422p -c:a pcm_s16le
