///////////////////////////////////////////////////////////////////////////////
// Internal implementation details
///////////////////////////////////////////////////////////////////////////////
//
// There are two levels of interfaces used to access the AOM codec: the
// aom_codec_iface and the aom_codec_ctx.
//
// 1. aom_codec_iface_t
// (Related files: aom/aom_codec.h, aom/src/aom_codec.c,
// aom/internal/aom_codec_internal.h, av1/av1_cx_iface.c,
// av1/av1_dx_iface.c)
//
// Used to initialize the codec context, which contains the configuration for
// for modifying the encoder/decoder during run-time. See the other
// documentation in this header file for more details. For the most part,
// users will call helper functions, such as aom_codec_iface_name,
// aom_codec_get_caps, etc., to interact with it.
//
// The main purpose of the aom_codec_iface_t is to provide a way to generate
// a default codec config, find out what capabilities the implementation has,
// and create an aom_codec_ctx_t (which is actually used to interact with the
// codec).
//
// Note that the implementations for the AV1 algorithm are located in
// av1/av1_cx_iface.c and av1/av1_dx_iface.c
//
//
// 2. aom_codec_ctx_t
// (Related files: aom/aom_codec.h, av1/av1_cx_iface.c, av1/av1_dx_iface.c,
// aom/aomcx.h, aom/aomdx.h, aom/src/aom_encoder.c, aom/src/aom_decoder.c)
//
// The actual interface between user code and the codec. It stores the name
// of the codec, a pointer back to the aom_codec_iface_t that initialized it,
// initialization flags, a config for either encoder or the decoder, and a
// pointer to internal data.
//
// The codec is configured / queried through calls to aom_codec_control,
// which takes a control ID (listed in aomcx.h and aomdx.h) and a parameter.
// In the case of "getter" control IDs, the parameter is modified to have
// the requested value; in the case of "setter" control IDs, the codec's
// configuration is changed based on the parameter. Note that a aom_codec_err_t
// is returned, which indicates if the operation was successful or not.
//
// Note that for the encoder, the aom_codec_alg_priv_t points to the
// the aom_codec_alg_priv structure in av1/av1_cx_iface.c, and for the decoder,
// the struct in av1/av1_dx_iface.c. Variables such as AV1_COMP cpi are stored
// here and also used in the core algorithm.
//
// At the end, aom_codec_destroy should be called for each initialized
// aom_codec_ctx_t.
/*!\defgroup codec Common Algorithm Interface
* This abstraction allows applications to easily support multiple video
* formats with minimal code duplication. This section describes the interface
* common to all codecs (both encoders and decoders).
* @{
*/
/*!\file
* \brief 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_dec_init() or aom_codec_enc_init() and a pointer to the
* algorithm's interface structure:
* <pre>
* my_app.c:
* extern aom_codec_iface_t my_codec;
* {
* aom_codec_ctx_t algo;
* int threads = 4;
* aom_codec_dec_cfg_t cfg = { threads, 0, 0, 1 };
* res = aom_codec_dec_init(&algo, &my_codec, &cfg, 0);
* }
* </pre>
*
* Once initialized, the instance is managed using other functions from
* the aom_codec_* family.
