Thanks for suggestion, but now the failure looks this way:
Streaming ioctls:
test read/write: OK
fail: v4l2-test-buffers.cpp(297): g_field() == V4L2_FIELD_ANY
fail: v4l2-test-buffers.cpp(703): buf.check(q, last_seq)
fail: v4l2-test-buffers.cpp(976): captureBufs(node, q, m2m_q, frame_count, false)
test MMAP: FAIL
Will check that later. If you have any suggestions, I would be very
grateful.
