Guys, I use motion for my old web camera (v4l1) with export LD_PRELOAD=/usr/lib/i386-linux-gnu/libv4l/v4l2convert.so v4l2convert.so run decompress helper ov511-decomp. Processes look like: /usr/bin/motion \_ /usr/lib/i386-linux-gnu/libv4lconvert0/ov511-decomp (motion - http://www.lavrsen.dk/foswiki/bin/view/Motion/WebHome) Everything works fine, but when I stop motion daemon I have to wait for a minute. strace prints that ov511-decomp got SIGTERM, wait for the minute and then got SIGKILL. When I do "killall -TERM ov511-decomp" ov511-decomp ignores it and continue to decomress. "killall -INT ov511-decomp" ov511-decomp shut down as expected. As a workaround I made this patch to lib/libv4lconvert/helper.c --- v4l-utils-1.0.1.orig/lib/libv4lconvert/helper.c +++ v4l-utils-1.0.1/lib/libv4lconvert/helper.c @@ -212,7 +212,7 @@ void v4lconvert_helper_cleanup(struct v4 void v4lconvert_helper_cleanup(struct v4lconvert_data *data) { int status; if (data->decompress_pid != -1) { - kill(data->decompress_pid, SIGTERM); + kill(data->decompress_pid, SIGINT); waitpid(data->decompress_pid, &status, 0); close(data->decompress_out_pipe[WRITE_END]); -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
