I'm also seeing the black edge with above commands. (Except, I had to
precede the second command with -pix_fmt yuv420p to avoid seg faulting

I further found out that, the width should be a multiple of 8, not of
2 or 4, for my code to work correctly(output without the edge). I will
test this out with ffmpeg, too.
Thanks for your support again.
