Macro Definition Documentation

#define CHECK_CHANNELS_CONSISTENCY (   frame)
Value:
av_assert2(!(frame)->channel_layout || \
(frame)->channels == \
int av_get_channel_layout_nb_channels(uint64_t channel_layout)
Return the number of channels in the channel layout.
#define av_assert2(cond)
assert() equivalent, that does lie in speed critical code.
