I recommend you use the media_tree.git master branch: v4l2-compliance is always in sync with that one. I'm not getting the issues you show below with v4l2-compliance -s (although once it starts streaming I get sequence errors, see the patch I posted that fixes that). So use the media_tree master branch and use the latest v4l2-compliance. If you still get the error you see below, then that needs to be investigated further, since I don't see it. However, testing with v4l2-compliance -f (which tests scaling) just stalls: Test input 0: Stream using all formats: test MMAP for Format UYVY, Frame Size 6x4: It sits there until I press Ctrl-C. This is NTSC input, BTW.
