This always fails with -EINVAL because of this issue. Currently GStreamer > throws a warning if the return value is an error other than -ENOTTY. But for now, this seems like a fair thing to do. We currently assume that if your driver is not implementing CROPCAP, then pixel aspect ratio at output will be unchanged at capture. If there is an error though, it's not good sign, and we report it. If that is wrong, let us know why and how to detect your driver error isn't a an error. cheers, Nicolas -- 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
