    skip_try_fmt_probes quirk is set, V4L2 object will not probe for
    interlace-mode and colorimetry to avoid relying on try_fmt. This quirk
    will be used by v4l2src to avoid desastrous startup time with slow
    USB webcams.

    negotiated caps as it may contains unsupported formats. If the peer
    didn't choose a specific interlace-mode, or colorimetry, the value
    chosen by the driver is set into the caps. For this reason, when this
    mode is enabled, gst_v4l2_object_set_format() will require writable
