Ah, unfortunately there *are* functional changes.
There is a (much) more extensive test that is done in the test-media script.
In v4l-utils, go to contrib/test. Now run (as root): test-media vicodec
This test now fails on some tests for the stateful decoder:
Streaming ioctls:
test read/write: OK (Not Supported)
test blocking wait: OK
fail: v4l2-test-buffers.cpp(943): ret == 0
fail: v4l2-test-buffers.cpp(1353): captureBufs(node, node_m2m_cap, q, m2m_q, frame_count, pollmode, capture_count)
test MMAP (select): FAIL
fail: v4l2-test-buffers.cpp(951): ret == 0
fail: v4l2-test-buffers.cpp(1353): captureBufs(node, node_m2m_cap, q, m2m_q, frame_count, pollmode, capture_count)
test MMAP (epoll): FAIL
fail: v4l2-test-buffers.cpp(943): ret == 0
fail: v4l2-test-buffers.cpp(1607): captureBufs(node, node_m2m_cap, q, m2m_q, frame_count, pollmode, capture_count)
test USERPTR (select): FAIL
fail: v4l2-test-buffers.cpp(943): ret == 0
fail: v4l2-test-buffers.cpp(1761): captureBufs(node, node_m2m_cap, q, m2m_q, frame_count, pollmode, capture_count)
test DMABUF (select): FAIL
I also see this:
cmp: EOF on /tmp/tmp.7KAXKAIkVZ/raw.yu12.1280.24 after byte 23500800, in line 1
which shouldn't be there either.
I can recommend the test-media script: it can test all the virtual drivers and it is
part of the daily build to check for regressions.
