[FFmpeg-user] Make white of photo transparant

[Cecil Westerhof]

I am still experimenting with ffmpeg.
At the moment I have the folowing:
     ffmpeg -y -ss 21:50 -to 23:20 -i input.MTS -i Photos/output.jpg                \
            -filter_complex "[0:v][1:v] overlay=0:-10:enable='between(t, 5, 85)'"   \
            -pix_fmt yuv420p -acodec copy -vcodec libx264 -preset veryfast -crf 26  \
            output.mp4

The background of the photo is white. Would it be possible to make
that transparent? (So where there is white, I do not see white, but
the video.)
