#define av_assert0 (   cond)
Value:
do { \
if (!(cond)) { \
av_log(NULL, AV_LOG_PANIC, "Assertion %s failed at %s:%d\n", \
AV_STRINGIFY(cond), __FILE__, __LINE__); \
abort(); \
} \
} while (0)

assert() equivalent, that is always enabled.

Examples:
muxing.c, and transcode_aac.c.

#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.
