2013-12-31Avoid using empty macro arguments.Reimar Döffinger
These are not supported by all compilers (gcc 2.95 but also older SPARC compilers, see gcc bug #33304 for example), and there is no real need for them. One use of this feature remains in libavdevice/v4l2.c which can't be replaced quite as easily. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>

format max value The constant may change in libavutil but the library may be compiled against an older version, thus rejecting a value which is otherwise supported by the new libavutil. INT_MAX is used here to denote the max allowed value for a sample format. The opt-test code is changed to provide a valid reference example.
