I used this a long time ago, but after googling for the error "from bgra to yuv420p" I guess that is a problem with the color space conversion that memcoder tries to enforce by default. Maybe you could try imposing the color space by adding -vf "format=bgra", but I think that the video codec is not going to be happy about that. Try looking around for other options...
