Yea I got it built. 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); fail_on_test(pixelformat != V4L2_PIX_FMT_JPEG && colorspace == V4L2_COLORSPACE_JPEG); fail_on_test(colorspace >= 0xff);

Will probably have to get another patch setup for that blocking dequeue I guess, but would appreciate any feedback on this patch.
