Still no SHA :( But this is with HEAD at commit 3874aa8eb1ff0c2e103d024ba5af915b1b26f098 > > FYI I am also patching out the JPEG thing I mentioned, so that the streaming test will run: > diff --git a/utils/v4l2-compliance/v4l2-test-formats.cpp b/utils/v4l2-compliance > index 02c2ce9..1f6eaa5 100644 > --- a/utils/v4l2-compliance/v4l2-test-formats.cpp > +++ b/utils/v4l2-compliance/v4l2-test-formats.cpp > @@ -330,7 +330,7 @@ static int testColorspace(__u32 pixelformat, __u32 colorspac > fail_on_test(!colorspace); > fail_on_test(colorspace == V4L2_COLORSPACE_BT878); > fail_on_test(pixelformat == V4L2_PIX_FMT_JPEG && > - colorspace != V4L2_COLORSPACE_JPEG); > + colorspace != V4L2_COLORSPACE_SRGB); I dropped this bogus test from v4l2-compliance. It doesn't make sense. Regards, Hans
