I am trying hard not to ask any silly questions. I have read the webpage,
the code, and the doc/ directory. I am still helpless:
I cannot find an introduction to using libavfilter. The doxygen docs are
readable, but a working example or introduction could be useful as well.
I don't see where libavfilter is used within ffmpeg. What am I
overlooking? Also I notice that within ffmpeg.c cropping (with -topcrop
etc.), padding (with -padtop etc.) and scaling (with -s) are coded
directly. I would have expected libavfilter to be used there, if it were
available and working.
Thanks for any clarifications.
