Should be "video_size" and "framerate" instead of "s" and "r".
(Doesn't matter for "s" iirc, can matter for "r".) More important (and sorry if you don't find this obvious):
Your command line does very different things and it is difficult for us to guess were the issue is - do you see the same problems with file output (and different options for v4l2)?

Please understand that only current FFmpeg git head is supported.
It seems very unlikely to me that FFmpeg produces the lines.
So using a beaglebone board (similar to raspberry pi board..) with web cam attached.
I also had to sync the frame framerate (input and output) since it was running super fast....and that seemed to help the speed issue
I tried -re but that didn't work...
From the video - looks like a frame index (or interlacing) problem...see attached video - if you look at the video full screen and pause - looks like every 40 lines or so I get a horizontal line (which is shifted left/right about 50%) then image is good again for a bit - then another horizontal line...
