Hi ffmpeg,

I am trying to use FPS filter in my code but I wasn't able to find any
manual or tutorial that would describe using libavfilter. Could anyone
explain what steps need to be undertaken in order to successfully employ
the FPS filter in my code? I looked at the doc/examples/video_filtering.c
but it is unclear on whether I need to use buffer and buffersink, and
whether the filter is being employed automatically or I need to call the
filtering myself. Thank you.
