Describes the codec algorithm interface to applications.
This file describes the interface between an application and a video codec algorithm.
An application instantiates a specific codec instance by using aom_codec_init() and a pointer to the algorithm's interface structure:
my_app.c:
extern aom_codec_iface_t my_codec;
{
aom_codec_ctx_t algo;
res = aom_codec_init(&algo, &my_codec);
}
Once initialized, the instance is managed using other functions from the aom_codec_* family.
