Yes Klaus and Bill , i did the FreeBSD port and maybe that definition was not the better one :-/ As you said bktr is the FreeBSD driver to access to TV capture card ( as V4L is in linux ). > 2) Reading through the sources, it appears that the config option is only > effective when used under the FreeBSD operating system.

You're right again , --without-bktr is in FreeBSD as --without-v4l is in linux . That option avoid to include in motion code from v4l/bktr and only include code for network cameras making the motion binary smaller. > Proposed patches for any of the Motion source files, including those used= for > configuration, are always welcome :-). >=20 > Bill Cheers, --=20 Angel Carpintero ack ( at ) telefonica ( dot ) net Key fingerprint =3D 3FD3 9C90 149E 7824 CECD 6BCF AC2C CA61 6EF1 B90D "No basta saber, hay que aplicar lo que se sabe;=20 no basta querer hacerlas cosas, hay que hacerlas".
