We have test to make sure that certain configurations do print warnings. However, the normal operation of the muxer within this test always printed a warning, so those tests to check for extra warnings didn't essentially guard anything. The warning that always was printed, "track 1: codec frame size is not set" was not present in the libav fork where this testcase originated, it was removed in f234e8a32e6c69d7b63f8627f278be7c2c987f43. Set the frame size for the audio stream to silence the warning, and use this frame size in a couple later calculations, and check that one test configuration doesn't print warnings. Setting the frame size apparently changes the rounding of a timestamp in the ismv muxing testcase. Signed-off-by: Martin Storsjö <martin@martin.st>
