The message comes out of pwcview.c:
...
if(ioctl(fd,VIDIOCGPICT,&vp) == -1) {
perror("Failed to get current picture info");
exit(1);
}
vp.palette = VIDEO_PALETTE_YUV420P;
if(ioctl(fd,VIDIOCSPICT,&vp) == -1) {
perror("Failed to set palette to YUV420P");
exit(1);
}
...
# fgrep VIDEO_PALETTE_YUV420P *.h
videodev.h:#define VIDEO_PALETTE_YUV420P 15 /* YUV 4:2:0 Planar */
Does it make sense to just comment out this ioctl(2) in pwcview.c?
