A device can support more than one colorspace for a given image dimension and pixel format. So we have to probe all the supported colorspace and not only rely on the default one. Otherwise we could end up with negotiation failure if the caps colorimetry field don't match the v4l2 device default one even if the v4l2 could support such colorimetry. This patch enable probing if colorspace for both capture and output device. It really makes sense for output device since the colorspace shall be set by the application and a little less for capture device which, at the moment, shall provide the colorspace; ie: the v4l2 specification seems to not take into account the fact that a capture device could do colorspace conversion. As a side effet, probing takes some times and so sligthly delay v4l2 initialization. Note that this patch only probe colorspace and not all colorspace, matrix, transfer and range combination to avoid taking too much time, especially with low-speed devices as full probing do 1782 ioctl. https://bugzilla.gnome.org/show_bug.cgi?id=755937 |
