#define av_assert0

(

cond

)

Value:

do {                                           \
    if (!(cond)) {                                                      \
        av_log(NULL, AV_LOG_FATAL, "Assertion %s failed at %s:%d\n",    \
               AV_STRINGIFY(cond), __FILE__, __LINE__);                 \
        abort();                                                        \
    }                                                                   \
} while (0)

assert() equivalent, that is always enabled.

#define av_assert1

(

cond

)

((void)0)

assert() equivalent, that does not lie in speed critical code.

These asserts() thus can be enabled without fearing speedloss.
