Initialize a decoder instance

Initializes a decoder context using the given interface. Applications should call the aom_codec_dec_init convenience macro instead of this function directly, to ensure that the ABI version number parameter is properly initialized.

If the library was configured with cmake -DCONFIG_MULTITHREAD=0, this call is not thread safe and should be guarded with a lock if being used in a multithreaded context.

\param[in] ctx Pointer to this instance’s context. \param[in] iface Pointer to the algorithm interface to use. \param[in] cfg Configuration to use, if known. May be NULL. \param[in] flags Bitfield of AOM_CODEC_USE_* flags \param[in] ver ABI version number. Must be set to AOM_DECODER_ABI_VERSION \retval #AOM_CODEC_OK The decoder algorithm has been initialized. \retval #AOM_CODEC_MEM_ERROR Memory allocation failed.
