They're all very computationally expensive, and do not have any ARM SIMD implementations. The deinterlacers from VLC use simple mathematical averages optimized by SIMD, and have been used by VLC on such devices for many years. I don't have any hard numbers to share, but in my experience I can decode+deinterlace video for real time playback in VLC on any cheap Android phone, whereas other ffmpeg-based players cannot.
