This is true for the stateful encoder as well: setting the capture format can change the output format. For a decoder it is the other way around: setting the output format can change the capture format. Note that we don't have a stateless encoder spec yet, but it makes sense that it behaves in the same way in this respect as the stateful encoder. > >> >>> >>> * "fail: v4l2-test-controls.cpp(673): try_ext_ctrls returned an error (22)": >>> default values for mpeg2 ctrls are not suitable, so doing >>> get_ext_ctrl()+try_ext_ctrl() does not work. >> >> Hmm, this might require some changes to this test.
