For the same requirements, I use the alternative below:
ffprobe -f lavfi "movie=1080p24.mxf:s=v+a[in0][in1],[in0]blackdetect[out0];[in1]silencedetect[out1]" -show_frames -of json

There is only a single source : "movie", so one might expect better performance
(I did not ran any benchmark on my own) and better scalability (if more streams were available).
