configure has the line --enable-libv4l2 enable libv4l2/v4l-utils [no] And before the commit i mentioned, it had the line libv4l2_indev_deps="libv4l2" If you check alldevices.c, there's no indev called "libv4l2_indev", only one called "v4l2_indev". Since the latter had no dependency on libv4l2, it was of course always enabled by default. I changed that in 734ed38931 (see ticket #6729, where doing that fixed a failure). So that indev being auto-enabled might have been a mistake all this time. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
