Hi Moritz,
Hello,
I want to track an object and need the x,y coordinates of this object
for each frame.
Is it possible to write the output of the find_rect filter to a file?
I don't have any good command line for find_rect handy, but it should
work with something like this (untested, of course):
$ ffprobe -f lavfi -i movie=input.mp4,find_rect=options -show_entries
frame=pkt_pts_time:frame_tags=lavfi.rect.w,lavfi.rect.h,lavfi.rect.x,lavfi.rect.y
-of csv
The above command works fine, but is it possible to print the number of
the frame instead of the timestamp?
I did search the documentation for a list of variables, but didn't find
any. Also "pkt_pts_time" seems to be undocumented.
Michael
