Parse stream info from a buffer

Performs high level parsing of the bitstream. Construction of a decoder context is not necessary. Can be used to determine if the bitstream is of the proper format, and to extract information from the stream.

\param[in] iface Pointer to the algorithm interface \param[in] data Pointer to a block of data to parse \param[in] data_sz Size of the data buffer \param[in,out] si Pointer to stream info to update. The is_annexb member \ref MUST be properly initialized. This function sets the rest of the members.

\retval #AOM_CODEC_OK Bitstream is parsable and stream information updated. \retval #AOM_CODEC_INVALID_PARAM One of the arguments is invalid, for example a NULL pointer. \retval #AOM_CODEC_UNSUP_BITSTREAM The decoder didn’t recognize the coded data, or the buffer was too short.
