[FFmpeg-devel] Ffmpeg with own filter

[Semen Zaytsev]

I defined my filter in those files, and i string about configure this
filter in config.mak, I move content of vf_edgedetect.c to vf_foobar.c,
defined in makefile and in allfilters.c, when i trying to use "ffmpeg -i
http://samples.ffmpeg.org/image-samples/lena.pnm -vf foobar foobar.png".
I'm receiving [AVFilterGraph @ 00000000003a8c40] No such filter:
'foobar' Error opening filters!
