Hi,

I noticed you do the following:

+#ifdef V4L2_FMT_FLAG_EMULATED
+ gboolean emulated = ((flags & V4L2_FMT_FLAG_EMULATED) != 0);
+#else
+ gboolean emulated = FALSE;
+#endif

Notice however that the V4L2_FMT_FLAG_EMULATED won't show up in Linux kernel
headers until 2.6.32, where as many distro's will (hopefully) have libv4l-0.6.1
which sets this flag before then.

libv4l contains the following which you may want to use (for a while atleast)
instead:

#ifndef V4L2_FMT_FLAG_EMULATED   
#define V4L2_FMT_FLAG_EMULATED 0x0002
#endif

Regards,

Hans
